<h1>ANALYSIS OF COMBUSTION CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass fuels have high oxygen web content and high natural volatiles, which will certainly create huge amounts of unpredictable gases during the combustion stage. Both the vapor stage combustion of the volatiles launched during the fuel home heating pyrolysis process happens, and also solid multiphase burning takes place throughout the coke oxidation process. The volatiles burn extremely promptly, practically the exact same price as the volatiles, and the oxidation of coke is much slower. Biomass burning can be separated into 3 stages, the first stage is the dehydration phase, the 2nd stage is the unstable analysis combustion stage, as well as the 3rd phase is the coke burning stage.



BURNING CHARACTERISTICS OF BIOMASS PELLETS AT VARIOUS HEATING PRICES.

The combustion-supporting gas is a mix of oxygen and also nitrogen with an oxygen material of 20%. The TG as well as DSC contours of biomass bits melting at different heating rates show that the heating rate has a higher influence on the combustion of biomass particles. As the price of temperature level rise rises, the exhaustion temperatures of various types of biomass particles enhance. The last deposit quality of the burning of biomass bits additionally increases with the boost of home heating price, however the boost is not noticeable. When the home heating rate is readied to 20 ° C · min-1, the final deposit top quality of biomass fragments is melted. maximum. The rise in the price of temperature increase additionally increases the price of weight reduction of the biomass. The rate of fat burning when the home heating rate is 30 ° C · min-1 is much higher than the other 2 type of heating rate, and also the TG contour is smoother than the other two.



Combustion features of biomass pellets in various oxygen materials.

Different oxygen degrees have a considerable result on the TG and also DSC curves of biomass pellet burning.




The oxygen web content in the combustion-supporting gas is increasing, to ensure that the burn-out temperatures of different sorts of biomass particles are minimized. The effects of the last residue high quality on the combustion of various sorts of biomass particles are not the very same. The adjustment in oxygen web content has little result on the last deposit top quality of the sawdust particles and also the rice husk fragments, as well as the final deposit high quality of the two biomass fragments continues to be substantially the same. For shavings bits, the last mass of the shed is 20% at the oxygen material. As the oxygen material of the straw granules remains to boost, the final residue quality additionally increases, reaching an optimum at an oxygen material of 33%.




The oxygen web content has a significant impact on the DSC curve of the biomass fragments. The various other oxygen content of combustion-supporting gas is increasing, and also the exothermic optimal of different type of biomass fragments is also enhancing. When wood pellet press machine is 33%, the exothermic height of biomass fragment combustion reaches the optimum. The temperature at which the exothermic optimal gets to the maximum also decreases with the increase of oxygen material, and the temperature level is the most affordable when the oxygen material is 33%.



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

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



The TG curves of refined rice husks as well as unrefined rice husks are substantially different. hand operated pellet machine of the refined rice husk is much smaller than that of the unprocessed rice husk, and also the burned temperature of the processed sawdust is also more than that of the unprocessed sawdust. The difference in the DSC curve of rice husk is likewise apparent. The DSC contour of the unprocessed sawdust reveals 2 distinctive exothermic peaks, as well as the initial exothermic height as well as the second exothermic peak are quite various. After the handling and forming procedure, the sawdust DSC contour has 2 similar exothermic tops.
