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


Biomass fuels have high oxygen material and also high organic volatiles, which will create large quantities of unpredictable gases during the burning phase. Both the vapor phase burning of the volatiles released during the gas home heating pyrolysis procedure takes place, and also solid multiphase combustion takes place during the coke oxidation procedure. The volatiles shed very promptly, practically 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 stage, the second phase is the volatile analysis combustion stage, as well as the 3rd phase is the coke burning stage.


COMBUSTION QUALITIES OF BIOMASS PELLETS AT VARIOUS HEATING PRICES.
The combustion-supporting gas is a mix of oxygen and also nitrogen with an oxygen web content of 20%. The TG as well as DSC curves of biomass fragments burning at various heating rates show that the home heating rate has a greater influence on the combustion of biomass bits. As the price of temperature rise boosts, the fatigue temperatures of various kinds of biomass fragments enhance. The final residue top quality of the combustion of biomass fragments additionally enhances with the increase of home heating rate, however the boost is not apparent. When the home heating rate is readied to 20 ° C · min-1, the final residue quality of biomass particles is burned. maximum. The rise in the rate of temperature level boost likewise raises the rate of weight loss of the biomass. The price of weight management when the home heating price is 30 ° C · min-1 is a lot more than the other 2 type of heating price, and also the TG contour is smoother than the other 2.

Burning characteristics of biomass pellets in different oxygen components.
Different oxygen levels have a substantial effect on the TG as well as DSC contours of biomass pellet burning.

extruder pellet machine in the combustion-supporting gas is enhancing, to ensure that the burn-out temperatures of various sorts of biomass fragments are minimized. The effects of the last deposit high quality on the burning of different kinds of biomass bits are not the exact same. The adjustment in oxygen web content has little effect on the final deposit high quality of the sawdust fragments and also the rice husk particles, and also the last residue high quality of both biomass particles stays considerably the same. For shavings fragments, the final mass of the shed is 20% at the oxygen content. As the oxygen web content of the straw granules continues to enhance, the final deposit top quality also enhances, reaching an optimum at an oxygen content of 33%.

The oxygen content has a significant impact on the DSC contour of the biomass fragments. The various other oxygen web content of combustion-supporting gas is raising, and the exothermic top of different type of biomass particles is also boosting. When the oxygen content is 33%, the exothermic top of biomass particle combustion gets to the optimum. The temperature at which the exothermic peak gets to the optimum likewise decreases with the boost of oxygen web content, and also the temperature is the most affordable when the oxygen content is 33%.

Contrast of burning attributes of processed biomass pellets as well as unprocessed biomass.
Burning atmosphere: The heating rate is 20 ° C · minutes -1, and also the oxygen content of the combustion-supporting gas is 20%. It can be known from the TG and also DSC contours of biomass burning of various handling modern technologies, whether the biomass is refined or otherwise, and the burning particular curve is obviously different.

The TG curves of processed rice husks as well as unrefined rice husks are significantly various. pto pellet machine of the processed rice husk is much smaller sized than that of the unprocessed rice husk, and also the shed temperature of the processed sawdust is additionally greater than that of the unprocessed sawdust. The difference in the DSC contour of rice husk is likewise obvious. The DSC contour of the unprocessed sawdust shows 2 distinct exothermic peaks, as well as the very first exothermic peak and the second exothermic optimal are rather various. After the processing and creating procedure, the sawdust DSC contour has two similar exothermic peaks.
