<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS</h1><br>
Biomass fuels have high oxygen content and high organic volatiles, which will generate large amounts of unstable gases throughout the burning phase. Both the vapor stage combustion of the volatiles launched during the gas heating pyrolysis process occurs, and solid multiphase combustion occurs throughout the coke oxidation procedure. The volatiles melt really swiftly, practically the same price as the volatiles, and also the oxidation of coke is a lot slower. Biomass combustion can be divided into three phases, the first stage is the dehydration phase, the 2nd stage is the unpredictable analysis combustion phase, and also the 3rd phase is the coke combustion phase.



COMBUSTION ATTRIBUTES OF BIOMASS PELLETS AT VARIOUS HOME HEATING PRICES.

The combustion-supporting gas is a blend of oxygen and nitrogen with an oxygen content of 20%. The TG as well as DSC curves of biomass fragments burning at various heating prices show that the heating rate has a higher influence on the burning of biomass bits. As floating pellet machine of temperature level boost rises, the exhaustion temperatures of different types of biomass particles boost. The last deposit top quality of the burning of biomass particles also enhances with the boost of home heating price, however the boost is not apparent. When the home heating rate is set to 20 ° C · min-1, the final residue top quality of biomass particles is melted. optimum. The rise in the rate of temperature rise likewise raises the price of weight-loss of the biomass. The price of weight loss when the home heating price is 30 ° C · min-1 is a lot more than the other two sort of home heating price, as well as the TG curve is smoother than the other 2.



Burning features of biomass pellets in different oxygen components.

Various oxygen levels have a considerable impact on the TG and also DSC contours of biomass pellet combustion.



The oxygen web content in the combustion-supporting gas is increasing, to make sure that the burn-out temperature levels of various types of biomass particles are lowered. The effects of the final residue quality on the combustion of various sorts of biomass particles are not the exact same. The change in oxygen content has little impact on the final residue top quality of the sawdust particles and also the rice husk bits, as well as the last residue high quality of the two biomass particles continues to be considerably the same. For shavings bits, the last mass of the melt is 20% at the oxygen content. As alfalfa pelletizer of the straw granules continues to enhance, the final residue quality likewise increases, reaching an optimum at an oxygen material of 33%.



The oxygen content has a substantial result on the DSC curve of the biomass fragments. The various other oxygen content of combustion-supporting gas is increasing, as well as the exothermic height of various kinds of biomass fragments is likewise raising. When the oxygen content is 33%, the exothermic optimal of biomass bit combustion reaches the maximum. The temperature at which the exothermic height gets to the optimum additionally decreases with the increase of oxygen web content, and also the temperature level is the most affordable when the oxygen content is 33%.




Comparison of burning attributes of processed biomass pellets as well as unprocessed biomass.

Combustion environment: The home heating price is 20 ° C · minutes -1, and also the oxygen web content of the combustion-supporting gas is 20%. It can be recognized from the TG and also DSC curves of biomass burning of various handling technologies, whether the biomass is refined or not, and also the burning particular curve is undoubtedly various.



The TG curves of processed rice husks as well as unprocessed rice husks are dramatically various. The final deposit high quality of the refined rice husk is a lot smaller than that of the unprocessed rice husk, as well as the burned temperature of the processed sawdust is likewise higher than that of the unprocessed sawdust. The distinction in the DSC curve of rice husk is likewise noticeable. The DSC contour of the unprocessed sawdust reveals 2 distinct exothermic tops, and the very first exothermic optimal and the second exothermic top are quite different. After the processing and forming procedure, the sawdust DSC contour has 2 similar exothermic peaks.
