How can I improve the combustion efficiency of a Home-Use Wood Pellet Mill by adjusting the temperature?
Core Logic: Appropriate temperature allows raw materials to fully soften and compact, resulting in higher particle density, more complete combustion, and higher calorific value. Temperatures that are too high or too low will lead to insufficient particle density or carbonization, reducing combustion efficiency.
Home use pellet mill/wood pelletizer has the best temperature range.
Firstly, to improve combustion efficiency, the optimal temperature range for different raw materials is defined: softwood chips 80-85℃, hardwood chips 95-100℃, and straw 90-95℃. This temperature range ensures fully formed pellets without carbonizing the raw materials, maximizing the preservation of their calorific value.
The effect of temperature on small biomass wood Pellet mill
The impact of low temperature on combustion efficiency and its adjustment: At low temperatures, the lignin in the raw materials is not fully softened, resulting in loose particles with low density (below 1.1 g/cm³). During combustion, air easily enters the particles, leading to rapid combustion, low calorific value, and the production of a large amount of ash. For example, when processing hardwood chips, at a temperature of only 85℃, the particle density is 0.95 g/cm³, and the calorific value is only 4200 kcal/kg. Raising the temperature to 98℃ increases the particle density to 1.15 g/cm³, and the calorific value reaches 4600 kcal/kg, improving combustion efficiency by more than 10%. Adjustment method: Gradually increase the temperature by 3-5℃ each time until the particle density reaches 1.1-1.2 g/cm³, at which point the combustion efficiency is optimal.
The impact of excessively high temperature on the combustion efficiency of the Biomass fuel pellet machine and its adjustment: Excessively high temperatures cause the surface of the raw material to carbonize, forming a hard shell. This prevents the internal lignin and fibers from burning completely, resulting in incomplete combustion, excessive smoke, and a decrease in calorific value. For example, when processing softwood chips, at 100℃, the particle surface carbonizes, resulting in excessive smoke and a calorific value of only 4300 kcal/kg. Lowering the temperature to 82℃ prevents carbonization, ensures complete combustion, and increases the calorific value to 4700 kcal/kg. Adjustment Method: Immediately reduce the temperature by 5-8°C each time, while simultaneously cleaning the carbonized material in the pressing chamber to prevent contamination of subsequent pellets. After adjustment, observe the appearance of the pellets to ensure there are no traces of carbonization, and then verify the calorific value through a combustion test.
