<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF VARIOUS KINDS OF BIOMASS</h1><br>
Biomass gas have high oxygen material and high natural volatiles, which will generate big amounts of unstable gases throughout the combustion phase. hay pellet making machine burning of the volatiles launched throughout the fuel heating pyrolysis procedure happens, and strong multiphase burning takes place throughout the coke oxidation procedure. The volatiles burn extremely rapidly, virtually the same rate as the volatiles, and the oxidation of coke is a lot slower. Biomass combustion can be divided right into three phases, the first stage is the dehydration stage, the 2nd stage is the unstable analysis burning stage, and the third phase is the coke combustion stage.



COMBUSTION QUALITIES OF BIOMASS PELLETS AT VARIOUS HOME HEATING PRICES.

The combustion-supporting gas is a mixture of oxygen and nitrogen with an oxygen web content of 20%. The TG and also DSC curves of biomass fragments melting at different home heating rates show that the home heating rate has a better influence on the burning of biomass bits. As the price of temperature boost rises, the burnout temperatures of various sorts of biomass particles enhance. The last residue top quality of the combustion of biomass particles likewise raises with the rise of heating rate, however the increase is not noticeable. When andritz pellet mill heating rate is set to 20 ° C · min-1, the last residue quality of biomass bits is shed. maximum. The increase in the rate of temperature boost additionally boosts the price of weight-loss of the biomass. The rate of weight management when the home heating rate is 30 ° C · min-1 is a lot higher than the various other 2 type of heating rate, as well as the TG contour is smoother than the various other 2.



Combustion characteristics of biomass pellets in various oxygen materials.


Different oxygen degrees have a substantial impact on the TG and also DSC curves of biomass pellet combustion.



The oxygen web content in the combustion-supporting gas is enhancing, so that the burn-out temperature levels of various types of biomass bits are decreased. The impacts of the last residue top quality on the combustion of different types of biomass bits are not the exact same. The modification in oxygen material has little result on the final deposit high quality of the sawdust fragments and also the rice husk particles, and also the final residue high quality of both biomass bits continues to be substantially unmodified. For shavings bits, the final mass of the burn is 20% at the oxygen web content. As the oxygen material of the straw granules remains to boost, the final residue top quality also boosts, getting to a maximum at an oxygen material of 33%.



The oxygen content has a significant result on the DSC contour of the biomass bits. The various other oxygen web content of combustion-supporting gas is enhancing, and also the exothermic peak of various sort of biomass fragments is additionally enhancing. When the oxygen content is 33%, the exothermic peak of biomass fragment burning gets to the maximum. The temperature at which the exothermic top gets to the optimum likewise decreases with the rise of oxygen material, as well as the temperature level is the lowest when the oxygen material is 33%.



Comparison of combustion attributes of processed biomass pellets and unrefined biomass.

Burning environment: The home heating price is 20 ° C · minutes -1, and the oxygen web content of the combustion-supporting gas is 20%. It can be recognized from the TG and DSC contours of biomass burning of various processing technologies, whether the biomass is processed or otherwise, as well as the burning characteristic contour is obviously different.




The TG contours of processed rice husks and also unrefined rice husks are considerably various. The final deposit high quality of the refined rice husk is much smaller sized than that of the unprocessed rice husk, and the shed temperature level of the refined sawdust is additionally more than that of the unrefined sawdust. The distinction in the DSC contour of rice husk is likewise noticeable. The DSC curve of the unprocessed sawdust reveals 2 distinctive exothermic optimals, and the first exothermic top and also the 2nd exothermic top are rather various. After the processing and developing procedure, the sawdust DSC curve has two comparable exothermic peaks.
