<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass fuels have high oxygen material and high natural volatiles, which will certainly produce large quantities of unpredictable gases throughout the burning phase. Both the vapor stage burning of the volatiles launched throughout the gas home heating pyrolysis procedure takes place, and solid multiphase combustion happens during the coke oxidation process. The volatiles burn very swiftly, virtually the same price as the volatiles, as well as the oxidation of coke is much slower. Biomass combustion can be separated right into three stages, the first stage is the dehydration stage, the second phase is the unstable analysis combustion stage, and also the third phase is the coke combustion stage.



BURNING CHARACTERISTICS OF BIOMASS PELLETS AT DIFFERENT HOME HEATING PRICES.

The combustion-supporting gas is a blend of oxygen and also nitrogen with an oxygen material of 20%. The TG and also DSC contours of biomass fragments burning at different home heating prices reveal that the heating rate has a greater effect on the burning of biomass particles. As the price of temperature increase rises, the burnout temperatures of different types of biomass bits enhance. The last deposit high quality of the burning of biomass fragments likewise enhances with the boost of heating rate, but the increase is not apparent. When the home heating price is set to 20 ° C · min-1, the final deposit top quality of biomass particles is shed. maximum. Richi machinery in the rate of temperature level increase likewise raises the price of weight reduction of the biomass. The price of weight reduction when the home heating price is 30 ° C · min-1 is much higher than the various other two sort of heating rate, and also the TG curve is smoother than the various other 2.




Combustion attributes of biomass pellets in different oxygen components.

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



The oxygen web content in the combustion-supporting gas is enhancing, to make sure that the burn-out temperature levels of various types of biomass bits are reduced. The results of the last deposit quality on the combustion of different kinds of biomass particles are not the very same. The change in oxygen web content has little impact on the last residue top quality of the sawdust particles and also the rice husk fragments, as well as the final residue top quality of both biomass bits continues to be substantially unchanged. For shavings particles, the last mass of the melt is 20% at the oxygen material. As the oxygen web content of the straw granules continues to raise, the final deposit high quality additionally increases, reaching a maximum at an oxygen web content of 33%.



The oxygen content has a significant impact on the DSC curve of the biomass particles. The various other oxygen content of combustion-supporting gas is raising, as well as the exothermic top of different kinds of biomass bits is likewise increasing. When my website is 33%, the exothermic top of biomass bit burning reaches the maximum. The temperature level at which the exothermic height reaches the optimum also decreases with the rise of oxygen material, as well as the temperature is the lowest when the oxygen content is 33%.



Contrast of burning features of refined biomass pellets as well as unrefined biomass.

Combustion atmosphere: The home heating price is 20 ° C · min -1, and the oxygen content of the combustion-supporting gas is 20%. It can be known from the TG and DSC contours of biomass burning of various handling innovations, whether the biomass is processed or otherwise, as well as the burning characteristic contour is undoubtedly different.



The TG contours of refined rice husks and unrefined rice husks are dramatically various. The last deposit top quality of the refined rice husk is much smaller than that of the unrefined rice husk, and also the melted temperature level of the refined sawdust is also higher than that of the unprocessed sawdust. The difference in the DSC curve of rice husk is likewise apparent. The DSC contour of the unrefined sawdust reveals 2 distinctive exothermic optimals, and the first exothermic height as well as the 2nd exothermic peak are fairly different. After the processing and developing procedure, the sawdust DSC contour has 2 similar exothermic tops.
