<h1>ANALYSIS OF BURNING CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS</h1><br>
Biomass gas have high oxygen web content as well as high organic volatiles, which will create huge amounts of unstable gases throughout the burning phase. Both the vapor stage burning of the volatiles launched during the gas heating pyrolysis process takes place, and strong multiphase burning occurs throughout the coke oxidation procedure. The volatiles melt very promptly, nearly the exact same rate as the volatiles, and also the oxidation of coke is much slower. Biomass burning can be separated right into three phases, the initial stage is the dehydration phase, the second phase is the unstable evaluation combustion stage, and the 3rd stage is the coke combustion phase.



COMBUSTION FEATURES OF BIOMASS PELLETS AT DIFFERENT HEATING PRICES.

The combustion-supporting gas is a blend of oxygen and nitrogen with an oxygen web content of 20%. The TG and DSC contours of biomass bits shedding at various heating rates show that the home heating price has a better influence on the burning of biomass bits. As the price of temperature level rise increases, the exhaustion temperatures of different types of biomass bits raise. The last deposit high quality of the burning of biomass fragments additionally raises with the boost of heating price, however the boost is not obvious. When the home heating rate is set to 20 ° C · min-1, the final residue high quality of biomass fragments is shed. maximum. The boost in the price of temperature boost additionally boosts the rate of weight reduction of the biomass. The price of weight loss when the home heating price is 30 ° C · min-1 is much greater than the various other two sort of home heating price, as well as the TG contour is smoother than the various other two.



Combustion features of biomass pellets in different oxygen contents.

Different oxygen degrees have a substantial effect on the TG as well as DSC curves of biomass pellet combustion.



The oxygen content in the combustion-supporting gas is raising, to make sure that the burn-out temperature levels of various sorts of biomass fragments are minimized. The impacts of the final residue quality on the burning of various sorts of biomass bits are not the exact same. The adjustment in oxygen material has little result on the final residue quality of the sawdust bits and also the rice husk fragments, as well as the last residue high quality of the two biomass particles stays significantly unmodified. For shavings fragments, the last mass of the shed is 20% at the oxygen material. As the oxygen content of the straw granules remains to raise, the last residue top quality additionally boosts, getting to an optimum at an oxygen web content of 33%.




The oxygen material has a considerable effect on the DSC curve of the biomass bits. The various other oxygen material of combustion-supporting gas is increasing, as well as the exothermic optimal of different sort of biomass particles is likewise boosting. When the oxygen material is 33%, the exothermic height of biomass particle combustion reaches the maximum. The temperature level at which the exothermic peak reaches the maximum additionally decreases with the rise of oxygen web content, and the temperature level is the lowest when the oxygen material is 33%.



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

Burning setting: The heating rate is 20 ° C · minutes -1, as well as 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 different handling modern technologies, whether the biomass is refined or not, as well as the burning particular contour is clearly different.



The TG curves of refined rice husks and also unprocessed rice husks are considerably different. manual fish feed making machine of the refined rice husk is much smaller than that of the unrefined rice husk, and also the burned temperature level of the processed sawdust is likewise more than that of the unrefined sawdust. The difference in the DSC curve of rice husk is also noticeable. hen feed making machine of the unrefined sawdust shows 2 distinct exothermic tops, and also the initial exothermic peak and also the second exothermic optimal are rather various. After fish feed pellet machine and creating process, the sawdust DSC contour has 2 similar exothermic optimals.
