<h1>EVALUATION OF COMBUSTION CHARACTERISTICS OF DIFFERENT KINDS OF BIOMASS</h1><br>
hay pellet machine have high oxygen material as well as high natural volatiles, which will generate huge amounts of volatile gases during the burning phase. Both the vapor phase combustion of the volatiles released throughout the fuel home heating pyrolysis process occurs, and solid multiphase burning takes place during the coke oxidation process. The volatiles melt really swiftly, almost the exact same price as the volatiles, and the oxidation of coke is much slower. Biomass combustion can be split into three phases, the first stage is the dehydration phase, the second stage is the volatile evaluation combustion stage, and also the 3rd phase is the coke burning stage.



BURNING QUALITIES OF BIOMASS PELLETS AT DIFFERENT HOME HEATING PRICES.

The combustion-supporting gas is a mix of oxygen and also nitrogen with an oxygen material of 20%. The TG and DSC contours of biomass bits shedding at various home heating prices show that the home heating rate has a higher influence on the combustion of biomass bits. As the price of temperature level boost boosts, the exhaustion temperatures of various sorts of biomass fragments increase. The last residue high quality of the burning of biomass bits also boosts with the boost of heating rate, however the rise is not noticeable. When the home heating rate is readied to 20 ° C · min-1, the last deposit top quality of biomass fragments is shed. optimum. The rise in the rate of temperature boost likewise boosts the price of fat burning of the biomass. fertilizer pellet machine of weight-loss when the home heating rate is 30 ° C · min-1 is a lot more than the various other 2 sort of heating price, and the TG curve is smoother than the various other two.



Combustion characteristics of biomass pellets in different oxygen contents.

Various oxygen levels have a substantial impact on the TG as well as DSC curves of biomass pellet burning.



The oxygen material in the combustion-supporting gas is boosting, to ensure that the burn-out temperatures of different sorts of biomass particles are lowered. The impacts of the last residue quality on the burning of various types of biomass fragments are not the exact same. The modification in oxygen material has little result on the final residue high quality of the sawdust fragments and the rice husk fragments, as well as the final deposit top quality of the two biomass particles continues to be significantly unmodified. For shavings bits, the last mass of the shed is 20% at the oxygen web content. As the oxygen content of the straw granules continues to enhance, the last deposit high quality also raises, reaching an optimum at an oxygen web content of 33%.



The oxygen content has a significant impact on the DSC curve of the biomass bits. The other oxygen content of combustion-supporting gas is boosting, and the exothermic optimal of different sort of biomass fragments is likewise increasing. When the oxygen content is 33%, the exothermic height of biomass particle combustion reaches the optimum. The temperature at which the exothermic height gets to the maximum also lowers with the increase of oxygen web content, as well as the temperature level is the lowest when the oxygen material is 33%.




Contrast of burning characteristics of processed biomass pellets and unrefined biomass.

Combustion setting: The heating price is 20 ° C · minutes -1, and also the oxygen web content of the combustion-supporting gas is 20%. It can be recognized from the TG and DSC curves of biomass burning of various processing modern technologies, whether the biomass is processed or not, and the burning particular contour is clearly various.



The TG curves of processed rice husks and unprocessed rice husks are significantly various. The final deposit quality of the processed rice husk is a lot smaller than that of the unprocessed rice husk, and the burned temperature level of the processed sawdust is also higher than that of the unrefined sawdust. The distinction in the DSC contour of rice husk is also evident. The DSC contour of the unprocessed sawdust reveals 2 unique exothermic tops, and the first exothermic top as well as the second exothermic top are rather various. After the handling and developing process, the sawdust DSC curve has two comparable exothermic optimals.
