Has XFA: No. Most fuels contain carbon and hydrogen, and the oxygen usually comes from air. Combustion generally consists of the following overall reactions: If too much oxygen is supplied, the mixture is lean and the reaction is oxidizing. This results in a flame that is relatively shorter. This typically results in a flame that is relatively longer and sometimes smoky. Most industrial burners are supplied with some excess air to mitigate the formation of unburned hydrocarbons, carbon monoxide and particulate matter. Air Requirements for Perfect Combustion The oxygen supply for combustion usually comes from air. Because air contains a large amount of nitrogen, the required volume of air is much larger than the required volume of oxygen. The nitrogen absorbs some of the heat released in the reaction resulting in a much lower flame temperature compared to a reaction in pure oxygen. Secondary air is usually the air that is brought in around the burner. Tertiary air is usually the air that is introduced downstream of the secondary air or through other openings in the combustion furnace. The lower or net heating value is the gross heating value minus the heat released by the condensation of the water vapor in the combustion products. The chemical composition of natural gas varies slightly depending upon the location in North America. The exact value for your fuel can be obtained from your local natural gas distribution utility. The values vary somewhat depending upon the natural gas composition. To see if our product is within the warranty period, refer to our guide to identifying manufacturing dates.

The measurements were carried out on various types of one.Concentrations of carbon monoxide (CO) and total organic carbon (TOC) are extremely variable at some operating schedules of combustion boilers. The variability of these concentrations indicates that there are unstable aerodynamic conditions in the combustion device. The causes of this aerodynamic instability have been studied. The mode with stable aerodynamic conditions, for which emission concentrations of CO and TOC are relatively stable, has been determined. The plants take an interest in reducing their negative impact or negative impression (of the black smoke) of the inhabitants without a more distinct investment. Wood represents one of the oldest materials used for heat and energy generation via direct or indirect burning. As fuel, wood can be evaluated similarly to any other solid fuel in accordance with the following criteria: chemical composition combustion heat and calorific value volatile matter content ash content The chemistry of wood combustion is a complex process. However, as a result of these reactions, in the flue gas created during the wood combustion not only carbon monoxide (CO) and NO x are present but also some other dangerous substances: CO 2, H 2 O, N 2, and unreacted surplus O 2. Moreover, in the imperfect oxidation of volatile matter products in the combustion chamber, the flue gas of wood contains different hydrocarbons, which concentration can be—from the point of view of the emission standards—expressed as total organic carbon (TOC). Wood contains more hydrogen than any other fuel which is the reason why significantly more hydrocarbons are created during its combustion. For this reason, the problem of hydrocarbon emissions from combustion can be considered to a certain degree as a specific problem related to the wood combustion process. Other harmful substances, such as, for example, polycyclic aromatic hydrocarbons (PAU), are not represented in wood structure. Their presence in flue gases is clear evidence of synthetic reactions in a flame. The original loosely connected cyclic hydrocarbons of wood are loosened in a flame and they condense at higher temperatures. Combustion of wooden waste with chlorine is a particularly serious problem. The aforementioned catalyser until recently was almost the only hardener of UF resins used. In 1 kg of particle board is there from 1 to 3.5 g of Cl. Theoretical calculation leads to chlorine concentration values (or HCl, resp. These concentrations significantly exceed present emission limits. Fuels with the compound ratio of phenol character and chlorine are the reason for a high probability of dioxin formation. The quality of wood and wood waste combustion in an enclosed combustion chamber depends on the water content and chemical composition of the wood itself and on combustion parameters. Combustion parameters of particular importance include: temperature in the combustion chamber, manner in which the individual phases of burning are separated, the surplus of air and its distribution into primary, secondary and even tertiary combustion processes, the thoroughness with which flammable gas mixes with air, and time (retaining period) during which flammable gas components are mixed with oxygen at the required reaction temperature (homogeneous oxidation). For energy generation from wood and wooden waste, different types of combustion equipment are used, which can be divided into: single stage two stage. The wood is partially broken down by pyrolysis and gasification in the preheating firebox through oxidation. In the second stage, the gaseous products from the first stage (primarily carbon monoxide and hydrocarbons) are burned with an appropriate surplus of air. In fact, there is no universal wood combustion device that can be used for every kind of biomass. New combustion plants generating electricity from biomass must comply with best available techniques (BAT) requirements. Detailed knowledge of the impact of combustion parameters on the formation of emissions is critical when developing such plants and in efforts to achieve additional reductions in emissions from existing plants. Emissions are minimised over the long term by using the lessons learned from monitoring emissions across a broad range of combustion plants fuelled by various types of biomass. This chapter is focused on resolving problems related to minimising emissions from the combustion of biomass. The aim of this chapter is to analyse the process of the biomass fuel and residues combustion and the emission production on the basis of emission measurements during the model combustion testing, and to propose solutions for minimising the emission of the investigated combustion plants. After preliminary evaluation of the structural design of the combustion plant and analyses of the biomass fuel or residues, it was decided to analyse in detail the process of combustion on the observed combustion plants. The generalisation of the results will be realised on the basis of comparing the experimental results with the results of producing the pollutants in the standard wood combustion plants. 2.1. Materials Cuttings of dry native wood, other biomass and waste from fibreboards, particleboards and other wood materials were used as fuel. The broader characteristic of these boilers will be described in this chapter. There were eight types of boilers used as the subject of research interest: Boiler 1: a boiler with a stationary horizontal grate with thermal input of approximately 200 kW for heat production for a small manufactory shop. The remains of a Sorghum biocolor var.Black smoke and unmeasurably high concentrations of CO and total organic carbon (TOC) emissions led to a boiler shutdown. An effort was made to keep this shop in a marginal zone and to verify the possibility of using another type of fuel with the aim of reducing emissions. An experiment with combustion of native wood briquettes was realised. During the experiment, manual briquette feeding was realised once per 60 min. Boiler 2: a gasifying boiler with a nominal output of 99 kW for combustion of piece rests of dry native wood residues with lengths up to 0.75 m from furniture production. Feeding of fuel to the boiler was performed manually. The original boiler was adapted in such a way that a primary combustion chamber was added to it and the original combustion chamber served as a secondary combustion chamber. Subsequently, the fuel falls to a horizontal grate where it is gasified by the substochiometric content of primary oxygen. The flammable gases formed burn out after mixing with the secondary air in the afterburning chamber under the boiler. Dosing of the fuel into the boiler can be automated or manual, therefore it is ideal for studying the operation modes. In the primary combustion chamber, there is a slope grate under which the strictly regulated primary combustion air is driven. Secondary combustion air and recirculated flue gas are driven to the entrance to the secondary combustion chamber. The boiler power and the addition of the combustion air are automatically regulated by variators on the basis of measurement of actual thermal parameters in different points of the combustion chambers and pressure. Boilers 7 (MA 23) and 8 (PU 25) for case study: The object of power, emission and safety operational testing was hot water boiler MA 23 for gasification of wood logs with nominal heat output of 23 kW ( Figure 2(a) ), and hot water boiler PU 25 with automatic feed fuel with nominal output of 23 kW ( Figure 2(b) ). Figure 2 (a) Gasification boiler MA 23 and (b) automatic boiler PU 25. The boilers are equipped with electronic temperature controller and a temperature safety fuse. Condition of the boiler and of its accessories was tested in accordance with the standardly supplied technical documentation. During testing, the influence of the conditions of fuel combustion on emissions was experimentally verified, as well as resistance to thermal overloading of the boiler and of equipment for removal of excess heat. Organic substance emissions expressed as total organic carbon (TOC) were continuously measured with a BERNATH ATOMIC analyser (Germany), acting on the principle of flame ionization detector (FID) and ThermoFid analyser. The representative sample taking process at the measuring point was executed at several measuring points of the piping cross section. The measuring points were selected in order to ensure an objective sample taking from the whole piping cross section. Smoke darkness measurements were conducted according to opacity in the Bacharach scale with a BRIGON company appliance (Germany). 3. Results and discussion Model combustion testing and measurements of emissions have analysed the process of production of pollutants in the process of biomass fuel and residues combustion. The knowledge of biomass—combustion technique—combustion conditions—emissions interactions is an essential prerequisite in these cases for minimising emissions from manually regulated combustion devices. When combusting the remains of a Sorghum biocolor var. The remains of the shrub were thin and burned quite rapidly. As a consequence of large burning velocity, no complete oxidation of burning products took place. We have not yet encountered a similar case in professional sources. Recognition of the causes of high concentrations of CO and TOC in flue gases enables the identification of solutions to minimise emissions from small boilers that currently are a long way off from the state of the art. A reduction of burning velocity can be achieved through addition of native wood briquettes. At smaller differences in the biomass density, such marked differences probably would not have become evident. The time behaviour of contaminating substance emissions (in recalculation to reference oxygen, 11 O 2 ) was monitored within the whole interval, starting with fuel feeding. Measuring points were located in a vertical duct system behind a waste gas fan. It can be seen that after briquette feeding, the CO concentration increases sharply. As emerged from these results, an acceptable solution could be more frequent feeding of a smaller fuel quantity at shorter intervals. This was confirmed by consequent analysis of the causes of dark smoke formation in the gasifying boiler with a nominal output of 99 kW. The gasifying boiler 2 with a nominal output of 99 kW often produced dark smoke. The boiler was expected to fulfil a single emission limit smoke darkness. The boiler operator was asked to periodically load fuel to the combustion chamber, to check temperature and pressure in the heat exchanger and to clean the device periodically. However, the regularity of feeding fuel from the viewpoint of emission minimisation was unknown. It was likewise unknown what the impact on concentrations of contaminating substances would have been for feeding dry, moist or even wet wood. The analysis of the time behaviour of emission creation on the basis of quite simple measurement of smoke darkness with proposed changes in feeding indicated possibilities for solving the problem of dark smoke creation ( Figure 5 ). Figure 5. Trends in time behaviour of smoke darkness (opacity in the Bacharach scale) development from time of feeding of dry native wood residues with lengths of up to 0.75 m in the gasifying boiler. By virtue of monitoring burning velocity, it can be said that this process is extremely rapid and thus highly susceptible to the formation of emission maxima. However, only dry native wood residues with lengths of up to 0.75 m are formed in operation. The combustion without emission maxima is for this reason possible only upon precise, uniform feeding at short time intervals. Dry wood burns quite rapidly after feeding and after black smoke appeared for several minutes with extremely high CO and TOC concentrations. When combusting boards bound by UF resin, a slower burning and a smaller emission extreme are visible in comparison with combustion of beech and pine waste lumber and cuttings after drying. However, securing conformity with the legal demands for air quality control is questionable. From a comprehensive analysis of results, it is clear that the thermal data and calorific value of biomass and biomass waste, in particular industrial wood waste, cannot be used as a basis for a regulation of the combustion process with the aim of minimising emissions. The results of the measurement of emissions under conditions of boiler operation set as a standard are given in Table 2. We then optimised boiler operation precisely for the given kind of fuel. All of the results of emission measurement analyses under operational conditions show that waste combustion of particleboards in smaller wood boilers can also be optimised in such a way that the demands of emission limits are met. In further experiments with wood and wood waste combustion, increased attention is paid to the operation of combustion equipment in a dynamic (not stable) regime. Dynamic states in operation of the combustion equipment are caused by a discontinuous dosing, or by continuous but not steady fuel dosing as well as by the regulation of incoming air. Emission characteristics measurements of the combustion equipment in a dynamic operation state were decided purposely due to the fluctuating heat take off from combustion equipment. The necessity to monitor the emission characteristics during dynamic operation of the combustion equipment is caused also by the fact that the majority of the fuel combustion processes is the power regulation. The fuel and air dosing is within the power regulation derived from the parameters of the heat transfer medium and its production. At the jump change of the dosing (loading of the furnace with the fuel), the oxidation conditions of organic gaseous substances and carbon monoxide become worse. After loading the fuel, CO concentration immediately grows rapidly ( Table 5 ). Probably the second stage of the combustion in this type of equipment does not meet all the construction requirements in order to achieve a high level of oxidation of organic gaseous substances. According to our calculations, this fact is caused by low temperature in the combustion chamber at the second stage (cooled by the boiler) and because flue gas remains in the chamber for a short time period.In this short phase, there is only the pyrolytic carbon and ashes in the primary combustion chamber. No gaseous organic substances are formed and CO concentrations are on the lowest level ( Table 6 ). In Table 7, average values are listed for the operation parameters and emissions during the whole fuel burning process under manual dosing—from loading until the end of continuous burning (up to 18 oxygen content in flue gas), immediately before the next fuel dose. When comparing the results of carbon monoxide and nitrogen oxides emissions measurements during the automated regime ( Table 4 ) and manual regime ( Table 7 ), it is evident that CO concentrations are at a higher level with manual dosing, and on the other hand, NO x concentrations are higher with automated dosing. The automated dosing regime is stable without emission extremes of carbon monoxide concentrations. With manual fuel dosing, there are phases with high concentrations and low production of nitrogen oxides. In this boiler, very good results of CO concentrations were reached when burning spruce bark with steady manual dosing ( Table 8 ). In both cases, low CO concentrations in flue gas were measured, which is caused by high calorific value of dry remains. The UF resin significantly increases the nitrogen content in fuel, which results in high values for NO x concentrations. Another goal of the emission limits measurements—when burning native wood and furniture residues from chipwood boards and MDF in boilers 5 and 6—was setting the highest possible ratio of this waste in order to keep to the emission limits. The results of our measurements ( Table 11 ) show that the combustion process itself is highly efficient and there are no problems to keep to the CO emission limits. In boiler 5, it is possible to keep to the emission limit for NO x with a ratio of the chipwood board in fuel up to 35. In order to evaluate a large number of emission measurement, we used the statistical method rotation in factor analysis. Varimax rotation is a useful statistical method used to simplify and better interpret the measuring results. We can identify and describe each variable with a single factor. The results of calculated varimax rotated factor matrix ( Table 12 ) enable to identify the influence of combustion conditions on the production of CO, TOC and NO x. On the other hand, a type of wood fuel does not influence this factor of “good burning” (when respecting suitability for the given combustion plant). This research shows further ways and means towards the realisation of measures to minimise emissions from the combustion of wood and wood waste. From the viewpoint of emission production, the decisive prevailing influence of the technique of wood waste combustion was proven in comparison with the influence of the chemical composition of wood waste. The knowledge and respecting the mechanism of producing pollutants are usable for regulation of emissions from atypical combustion plants or generally for minimisation of emissions in combustion plants. 4. Case study: example of minimisation of emissions by appropriate boiler regulation Emissions of individual pollutants at combustion of solid fossil fuels (black coal and lignite) and of biomass (wood pellets) in boilers can be found by the analyses of data obtained from different experiments or commercial measurements of emissions. It is possible to see from the measurement results that combustion of biomass does not always directly reduce the amount of harmful emissions generated. An important factor is particularly the manner of combustion control, which is given by the method of fuel supply, simply speaking by stoking. It is evident from the results that increased oxygen content in the flue gas increases the CO content, that is, the component, from which it is still possible to extract some heat and to reduce thus the loss of the unused fuel. This observation leads us to the fact that gas did not get enough time to react with oxygen and to transform to CO 2. Table 13 gives the percentage composition of real wet flue gas, when it is apparent that the percentage composition of the flue gas is affected also by the amount of flue gas. It consists of two chambers situated one above the other. The bottom of the combustion chamber contains an afterburner chamber in which the wood gas and solid residues are burned. Supply of combustion air is realised by radial fan. Figure 6. Hot water boiler MA 23—1. Stoking chamber, 2. Combustion chamber, 3. Fan, 4. Tube heat exchanger, 5. Chimney spout, 6. Electronic regulator, 7. Nozzle made of refractory concrete. The primary air is driven into the combustion chamber below the level of the upper door. This arrangement allows better gasification of larger pieces of wood. The flame thus does not cool down and combustibles burn up completely. The lower combustion chamber is lined with refractory concrete in which the final burning of all solid particles, which fall down, takes place. Figure 7(a) shows the original shaped piece through which the combustion air for secondary combustion was supplied by two large holes. Figure 7(b) shows the proposed shaped piece, which was also tested, through which the air was supplied along the longer side of the shaped piece by several holes. This resulted in a better reaction with the generated wood gas, in better burnout of gas and thus in the already mentioned reduction of emissions. Figure 7. (a) Original shaped piece and (b) newly designed shaped piece. Modification of combustion leads to reduction in generation of the gases we measured.
