<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass gas have high oxygen content as well as high organic volatiles, which will generate huge quantities of unpredictable gases throughout the combustion phase. Both the vapor stage burning of the volatiles released throughout the gas home heating pyrolysis process happens, as well as solid multiphase combustion occurs throughout the coke oxidation procedure. The volatiles melt very rapidly, virtually the same rate as the volatiles, and the oxidation of coke is much slower. Biomass combustion can be separated into three stages, the first stage is the dehydration stage, the 2nd stage is the unstable evaluation burning stage, and also the 3rd phase is the coke combustion stage.




BURNING QUALITIES OF BIOMASS PELLETS AT DIFFERENT HEATING RATES.

The combustion-supporting gas is a blend of oxygen and nitrogen with an oxygen content of 20%. The TG as well as DSC contours of biomass bits burning at various home heating prices reveal that the home heating price has a greater influence on the burning of biomass fragments. As the price of temperature level increase boosts, the burnout temperatures of various kinds of biomass bits enhance. The final residue top quality of the burning of biomass bits also increases with the boost of home heating price, yet the increase is not apparent. When the heating rate is set to 20 ° C · min-1, the final deposit top quality of biomass bits is melted. optimum. The increase in the rate of temperature boost additionally increases the rate of weight-loss of the biomass. The rate of weight reduction when the home heating price is 30 ° C · min-1 is a lot greater than the other two type of heating price, and also the TG curve is smoother than the various other two.



Burning qualities of biomass pellets in various oxygen contents.

Various oxygen levels have a considerable impact on the TG as well as DSC contours of biomass pellet burning.



The oxygen web content in the combustion-supporting gas is boosting, so that the burn-out temperatures of different types of biomass fragments are lowered. The impacts of the last residue top quality on the burning of different sorts of biomass particles are not the very same. The change in oxygen content has little result on the final deposit quality of the sawdust particles as well as the rice husk bits, and the final deposit top quality of the two biomass fragments stays significantly the same. For shavings particles, the last mass of the shed is 20% at the oxygen content. As the oxygen web content of the straw granules remains to increase, the last residue quality additionally boosts, reaching a maximum at an oxygen web content of 33%.



The oxygen material has a substantial result on the DSC curve of the biomass bits. sheep feed pellet machine of combustion-supporting gas is increasing, as well as the exothermic height of different kinds of biomass fragments is also boosting. When the oxygen material is 33%, the exothermic top of biomass fragment burning reaches the maximum. small feed pellet machine at which the exothermic top reaches the maximum also reduces with the increase of oxygen content, and the temperature is the lowest when the oxygen content is 33%.



Comparison of burning features of processed biomass pellets and unrefined biomass.

Combustion environment: The heating price is 20 ° C · min -1, as well as the oxygen web content of the combustion-supporting gas is 20%. It can be known from the TG and DSC curves of biomass burning of different handling technologies, whether the biomass is refined or not, as well as the burning characteristic curve is obviously various.



The TG curves of refined rice husks and also unrefined rice husks are significantly different. The final deposit high quality of the refined rice husk is a lot smaller sized than that of the unrefined rice husk, and the melted 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 noticeable. The DSC curve of the unrefined sawdust shows two unique exothermic peaks, as well as the first exothermic top and also the second exothermic peak are quite different. After the processing as well as developing process, the sawdust DSC curve has two comparable exothermic heights.
