ANALYSIS OF COMBUSTION CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS
ANALYSIS OF BURNING CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS

Biomass fuels have high oxygen web content and high natural volatiles, which will certainly generate huge amounts of volatile gases throughout the combustion stage. Both the vapor phase burning of the volatiles released during the fuel heating pyrolysis procedure happens, as well as solid multiphase burning occurs during the coke oxidation process. The volatiles shed really quickly, nearly the very same rate as the volatiles, as well as the oxidation of coke is much slower. Biomass burning can be divided right into three phases, the initial stage is the dehydration phase, the second stage is the volatile evaluation combustion phase, and also the third stage is the coke burning phase.

BURNING FEATURES OF BIOMASS PELLETS AT DIFFERENT HEATING PRICES.

The combustion-supporting gas is a combination of oxygen as well as nitrogen with an oxygen material of 20%. The TG and also DSC curves of biomass particles burning at various heating rates show that the heating rate has a higher impact on the combustion of biomass fragments. As the price of temperature rise boosts, the exhaustion temperatures of various sorts of biomass fragments enhance. The last deposit top quality of the combustion of biomass particles also boosts with the increase of home heating price, but the rise is not apparent. When the home heating price is set to 20 ° C · min-1, the final deposit top quality of biomass fragments is burned. optimum. animal feed pelletizer in the rate of temperature increase additionally raises the rate of weight management 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 home heating rate, as well as the TG curve is smoother than the various other 2.

Burning features of biomass pellets in various oxygen materials.
Different oxygen levels have a considerable impact on the TG and also DSC contours of biomass pellet combustion.

The oxygen web content in the combustion-supporting gas is raising, to make sure that the burn-out temperatures of various kinds of biomass particles are decreased. The results of the final residue quality on the combustion of different sorts of biomass bits are not the very same. The adjustment in oxygen web content has little impact on the last deposit top quality of the sawdust bits and the rice husk particles, and also the last deposit high quality of the two biomass particles stays considerably unchanged. For shavings particles, the last mass of the shed is 20% at the oxygen material. As the oxygen material of the straw granules continues to enhance, the last deposit top quality also enhances, getting to an optimum at an oxygen web content of 33%.

The oxygen web content has a considerable result on the DSC curve of the biomass fragments. The other oxygen material of combustion-supporting gas is enhancing, and also the exothermic optimal of different sort of biomass bits is also raising. When the oxygen content is 33%, the exothermic height of biomass fragment burning reaches the maximum. The temperature level at which the exothermic top gets to the maximum additionally decreases with the increase of oxygen web content, as well as the temperature is the lowest when the oxygen material is 33%.

Contrast of combustion features of processed biomass pellets and also unprocessed biomass.
Combustion environment: The heating rate is 20 ° C · min -1, and also the oxygen material of the combustion-supporting gas is 20%. It can be recognized from the TG and also DSC curves of biomass burning of different processing technologies, whether the biomass is processed or not, and also the burning characteristic contour is undoubtedly various.

The TG curves of refined rice husks as well as unprocessed rice husks are significantly different. The final residue top quality of the processed rice husk is much smaller sized than that of the unrefined rice husk, and the burned temperature of the processed sawdust is also more than that of the unprocessed sawdust. used cpm pellet mill for sale in the DSC contour of rice husk is additionally noticeable. The DSC contour of the unprocessed sawdust reveals 2 unique exothermic tops, and also the very first exothermic optimal and also the 2nd exothermic optimal are quite different. After the processing as well as creating process, the sawdust DSC curve has two similar exothermic optimals.
