<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS</h1><br>
Biomass gas have high oxygen content and high natural volatiles, which will certainly generate big amounts of volatile gases throughout the combustion stage. Both the vapor phase burning of the volatiles launched during the gas heating pyrolysis procedure happens, and also strong multiphase burning takes place during the coke oxidation process. pellet mill cooler , nearly the very same rate as the volatiles, as well as the oxidation of coke is a lot slower. Biomass combustion can be separated right into three stages, the initial stage is the dehydration stage, the second phase is the unpredictable evaluation burning stage, and also the 3rd stage is the coke combustion stage.



COMBUSTION FEATURES OF BIOMASS PELLETS AT DIFFERENT HOME HEATING RATES.

The combustion-supporting gas is a mixture of oxygen and also nitrogen with an oxygen content of 20%. The TG and DSC contours of biomass bits burning at different home heating rates show that the home heating price has a greater influence on the combustion of biomass particles. As the rate of temperature boost rises, the burnout temperature levels of various kinds of biomass fragments boost. The last deposit quality of the burning of biomass fragments likewise increases with the rise of home heating price, yet the boost is not apparent. When the heating price is readied to 20 ° C · min-1, the final residue top quality of biomass particles is melted. optimum. The increase in the rate of temperature level rise likewise increases the price of weight management of the biomass. price of poultry feed making machine of weight management when the heating price is 30 ° C · min-1 is a lot higher than the other two type of heating rate, and the TG curve is smoother than the other 2.




Combustion attributes of biomass pellets in different oxygen components.

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



The oxygen content in the combustion-supporting gas is enhancing, so that the burn-out temperature levels of various sorts of biomass particles are reduced. The impacts of the final deposit high quality on the burning of various kinds of biomass particles are not the same. The change in oxygen web content has little impact on the final deposit quality of the sawdust particles as well as the rice husk bits, and the final deposit high quality of the two biomass fragments remains significantly the same. For shavings bits, the last mass of the melt is 20% at the oxygen web content. As the oxygen material of the straw granules continues to increase, the final residue top quality additionally increases, reaching an optimum at an oxygen content of 33%.



The oxygen content has a significant result on the DSC contour of the biomass particles. The other oxygen material of combustion-supporting gas is raising, and also the exothermic optimal of different kinds of biomass bits is likewise boosting. When the oxygen material is 33%, the exothermic peak of biomass fragment combustion gets to the optimum. The temperature level at which the exothermic top gets to the maximum additionally lowers with the increase of oxygen material, as well as the temperature is the most affordable when the oxygen web content is 33%.



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

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



The TG contours of processed rice husks and also unprocessed rice husks are considerably different. The final residue high quality of the processed rice husk is a lot smaller than that of the unprocessed rice husk, and also the melted temperature of the processed sawdust is also greater than that of the unprocessed sawdust. The distinction in the DSC curve of rice husk is also noticeable. The DSC curve of the unrefined sawdust reveals two unique exothermic optimals, and the very first exothermic peak as well as the second exothermic top are fairly various. After the handling as well as creating process, the sawdust DSC curve has two comparable exothermic optimals.
