<h1>ANALYSIS OF COMBUSTION CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS</h1><br>
Biomass gas have high oxygen material and high natural volatiles, which will certainly generate large amounts of unpredictable gases throughout the combustion phase. Both the vapor stage combustion of the volatiles released during the fuel heating pyrolysis process happens, and also strong multiphase combustion occurs during the coke oxidation process. The volatiles burn extremely swiftly, virtually the very same rate as the volatiles, as well as the oxidation of coke is a lot slower. Biomass burning can be separated right into three stages, the first stage is the dehydration phase, the second stage is the unpredictable analysis combustion stage, as well as the 3rd phase is the coke burning phase.



COMBUSTION QUALITIES OF BIOMASS PELLETS AT DIFFERENT HOME HEATING RATES.

The combustion-supporting gas is a blend of oxygen and also nitrogen with an oxygen content of 20%. The TG and DSC curves of biomass particles melting at different home heating prices show that the heating rate has a greater effect on the combustion of biomass bits. As the rate of temperature increase boosts, the fatigue temperature levels of different kinds of biomass fragments increase. The final deposit top quality of the burning of biomass bits additionally raises with the rise of home heating rate, however the rise is not obvious. When the home heating price is readied to 20 ° C · min-1, the last deposit quality of biomass particles is shed. maximum. The rise in the price of temperature rise likewise raises the price of weight loss of the biomass. The rate of weight-loss when the heating price is 30 ° C · min-1 is much higher than the other 2 type of home heating price, and the TG contour is smoother than the various other 2.



Combustion qualities of biomass pellets in various oxygen materials.

Different oxygen degrees have a substantial effect on the TG and DSC contours of biomass pellet combustion.



The oxygen web content in the combustion-supporting gas is enhancing, to ensure that the burn-out temperatures of different kinds of biomass particles are minimized. The results of the last deposit quality on the burning of different kinds of biomass bits are not the very same. The modification in oxygen content has little impact on the final residue quality of the sawdust fragments and the rice husk particles, and the last residue top quality of the two biomass fragments remains significantly unchanged. For shavings particles, the final mass of the shed is 20% at the oxygen content. As the oxygen web content of the straw granules remains to boost, the final deposit high quality likewise boosts, reaching an optimum at an oxygen material of 33%.



The oxygen web content has a considerable effect on the DSC contour of the biomass particles. The various other oxygen material of combustion-supporting gas is increasing, as well as the exothermic top of different type of biomass fragments is likewise increasing. When the oxygen web content is 33%, the exothermic top of biomass particle combustion reaches the maximum. The temperature level at which the exothermic top gets to the maximum likewise decreases with the increase of oxygen content, and also the temperature level is the lowest when the oxygen content is 33%.



Comparison of combustion characteristics of processed biomass pellets as well as unrefined biomass.


Combustion setting: The home heating price is 20 ° C · minutes -1, and the oxygen material of the combustion-supporting gas is 20%. It can be known from the TG as well as DSC curves of biomass burning of various handling innovations, whether the biomass is processed or not, and also the burning particular curve is clearly various.



The TG contours of refined rice husks and also unrefined rice husks are substantially different. The final deposit quality of the refined rice husk is much smaller than that of the unrefined rice husk, as well as the burned temperature level of the refined sawdust is also greater than that of the unrefined sawdust. The distinction in the DSC curve of rice husk is also obvious. The DSC curve of the unprocessed sawdust shows two distinct exothermic heights, and also the initial exothermic top and also the second exothermic peak are rather various. After top article and developing procedure, the sawdust DSC contour has two similar exothermic heights.
