<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass fuels have high oxygen material as well as high natural volatiles, which will generate huge quantities of unpredictable gases during the combustion phase. Both the vapor stage burning of the volatiles launched during the fuel home heating pyrolysis process takes place, as well as strong multiphase burning takes place during the coke oxidation process. The volatiles melt very swiftly, nearly the exact same price as the volatiles, as well as the oxidation of coke is much slower. Biomass combustion can be divided right into 3 stages, the initial stage is the dehydration phase, the second stage is the unstable analysis burning stage, and the 3rd stage is the coke burning stage.



BURNING FEATURES OF BIOMASS PELLETS AT VARIOUS HOME HEATING RATES.


The combustion-supporting gas is a blend of oxygen and also nitrogen with an oxygen web content of 20%. The TG and DSC contours of biomass fragments burning at different home heating rates show that the heating rate has a greater impact on the burning of biomass particles. As the rate of temperature level rise rises, the exhaustion temperatures of different kinds of biomass particles increase. The last residue high quality of the combustion of biomass bits additionally boosts with the boost of heating rate, but the boost is not noticeable. When the heating rate is readied to 20 ° C · min-1, the last residue top quality of biomass fragments is burned. optimum. The boost in the price of temperature increase additionally enhances the rate of fat burning of the biomass. The price of weight loss when the heating price is 30 ° C · min-1 is much more than the other 2 sort of heating price, and also the TG curve is smoother than the various other 2.




Burning characteristics of biomass pellets in different oxygen components.

Different oxygen levels have a significant effect on the TG and also DSC contours of biomass pellet burning.



The oxygen content in the combustion-supporting gas is raising, to make sure that the burn-out temperature levels of various kinds of biomass bits are lowered. The results of the final residue high quality on the combustion of various types of biomass bits are not the same. The modification in oxygen web content has little effect on the final deposit quality of the sawdust bits as well as the rice husk fragments, and also the final residue high quality of both biomass particles stays substantially unchanged. For shavings bits, the final mass of the shed is 20% at the oxygen content. As the oxygen material of the straw granules remains to boost, the last deposit top quality also enhances, reaching a maximum at an oxygen web content of 33%.



The oxygen content has a significant impact on the DSC curve of the biomass bits. california pellet mill of combustion-supporting gas is boosting, and also the exothermic peak of various kinds of biomass particles is also enhancing. When the oxygen material is 33%, the exothermic top of biomass fragment combustion gets to the optimum. The temperature level at which the exothermic optimal gets to the maximum additionally reduces with the increase of oxygen web content, and also the temperature is the lowest when the oxygen content is 33%.



Comparison of burning attributes of refined biomass pellets as well as unrefined biomass.

Combustion atmosphere: The home heating price is 20 ° C · min -1, as well as the oxygen material of the combustion-supporting gas is 20%. It can be recognized from the TG as well as DSC curves of biomass burning of different processing technologies, whether the biomass is refined or not, and the burning characteristic contour is obviously various.



The TG contours of processed rice husks as well as unrefined rice husks are considerably different. The last deposit top quality of the refined rice husk is much smaller than that of the unprocessed rice husk, as well as the melted temperature of the processed sawdust is also higher than that of the unrefined sawdust. The distinction in the DSC curve of rice husk is likewise obvious. The DSC contour of the unprocessed sawdust reveals 2 distinctive exothermic peaks, and the very first exothermic top as well as the 2nd exothermic optimal are quite various. After the handling and also developing process, the sawdust DSC contour has 2 similar exothermic heights.
