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

Biomass fuels have high oxygen web content and also high natural volatiles, which will generate huge amounts of unpredictable gases throughout the burning phase. Both the vapor stage combustion of the volatiles launched throughout the fuel heating pyrolysis procedure happens, as well as strong multiphase combustion takes place during the coke oxidation procedure. gemco wood pellet machine , almost the exact same rate as the volatiles, and also the oxidation of coke is much slower. Biomass burning can be split into 3 phases, the first stage is the dehydration phase, the 2nd stage is the volatile analysis burning phase, as well as the third phase is the coke burning stage.

COMBUSTION CHARACTERISTICS OF BIOMASS PELLETS AT VARIOUS HOME HEATING RATES.
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 particles shedding at various heating rates reveal that the home heating rate has a higher impact on the burning of biomass bits. As the rate of temperature increase rises, the exhaustion temperature levels of various sorts of biomass fragments boost. The last residue quality of the burning of biomass particles additionally boosts with the boost of heating price, yet the boost is not noticeable. When the heating rate is set to 20 ° C · min-1, the final residue top quality of biomass fragments is melted. maximum. The boost in the price of temperature level increase also raises the rate of fat burning of the biomass. The price of weight management when the home heating price is 30 ° C · min-1 is a lot higher than the other 2 type of home heating rate, and the TG curve is smoother than the other two.

Burning qualities of biomass pellets in various oxygen contents.

Different oxygen degrees have a significant effect on the TG as well as DSC contours of biomass pellet burning.


The oxygen material in the combustion-supporting gas is boosting, to ensure that the burn-out temperature levels of different sorts of biomass bits are minimized. wood pellet bagging machine of the final deposit high quality on the combustion of various types of biomass fragments are not the same. wood pellet maker diy in oxygen material has little result on the last residue top quality of the sawdust fragments and the rice husk bits, as well as the last residue top quality of the two biomass bits remains significantly the same. For shavings particles, the last mass of the shed is 20% at the oxygen content. As the oxygen content of the straw granules continues to boost, the last deposit high quality also boosts, reaching an optimum at an oxygen material of 33%.

The oxygen material has a substantial effect on the DSC curve of the biomass bits. The various other oxygen content of combustion-supporting gas is increasing, as well as the exothermic peak of different type of biomass fragments is also boosting. When the oxygen web content is 33%, the exothermic height of biomass fragment burning reaches the optimum. The temperature level at which the exothermic peak gets to the optimum also decreases with the increase of oxygen material, and also the temperature is the lowest when the oxygen material is 33%.

Comparison of burning characteristics of refined biomass pellets and also unprocessed biomass.
Burning setting: The home heating price is 20 ° C · min -1, and also the oxygen content of the combustion-supporting gas is 20%. It can be understood from the TG and DSC curves of biomass burning of various handling modern technologies, whether the biomass is refined or not, and the burning particular curve is obviously various.

The TG contours of processed rice husks and unprocessed rice husks are considerably different. The final residue high quality of the refined rice husk is a lot smaller than that of the unrefined rice husk, as well as the burned temperature level of the refined sawdust is likewise higher than that of the unprocessed sawdust. The distinction in the DSC contour of rice husk is likewise noticeable. The DSC curve of the unprocessed sawdust shows two unique exothermic optimals, as well as the very first exothermic peak and also the 2nd exothermic peak are rather various. After the handling and developing process, the sawdust DSC contour has 2 comparable exothermic optimals.
