What are the requirements for the fuel quality of biomass pellets in Biomass Pellet Hot Air Furnace?
Publish Time: 2024-11-20
As an efficient and environmentally friendly heating equipment, Biomass Pellet Hot Air Furnace has been widely used in agriculture, industry and civil fields. Its core is to use biomass pellets as fuel, generate heat energy through combustion, and then achieve space heating or material drying through the hot air transfer system. However, in order to ensure the stable operation and efficient performance of the hot air furnace, the fuel quality of biomass pellets is crucial.First, the size of biomass pellets must meet certain requirements. Generally speaking, the diameter of the pellets should be between 6-10mm and the length should be moderate to ensure full combustion during the combustion process and reduce the generation of unburned particles. Too large particles may lead to incomplete combustion, while too small particles may increase furnace wear and fly ash generation.Secondly, the moisture content of biomass pellets is also a key factor. Too high a moisture content will reduce the calorific value of the pellets, increase energy consumption during combustion, and may cause coking or blockage of the furnace. Therefore, the moisture content of biomass pellets should be controlled within a certain range, usually not exceeding 10%.In addition, the calorific value and ash content of biomass pellets are also important indicators for evaluating their quality. Pellets with high calorific value can provide more stable combustion performance and higher heat output, while the ash content directly affects the slag treatment and environmental emissions after combustion. Generally speaking, the calorific value of high-quality biomass pellets should reach more than 4000 kcal, and the ash content should be controlled within a certain range to reduce the negative impact on the environment.In addition to the above requirements, biomass pellets should also have uniform color, smooth surface and good mechanical strength to ensure that they are not easy to break and produce impurities during storage, transportation and combustion.In summary, Biomass Pellet Hot Air Furnace has strict requirements on the fuel quality of biomass pellets. Only pellets that meet these requirements can ensure the stable operation, high-efficiency performance and environmental emissions of the hot air furnace. Therefore, when choosing biomass pellets as fuel for hot air furnaces, factors such as their size, moisture content, calorific value, ash content, and mechanical strength should be fully considered to ensure long-term stable operation and optimal performance of the equipment.
