The general characteristics of biomass fuel are high water content, low ash content, high volatile content, low calorific value, irregular shape, except for the outer shell (rice husk, walnut shell) and core (corn cob, peach pit, etc.) of some agricultural products. In addition to direct combustion, other fuels such as straw and tree branches must be processed before burning, so that they can be distributed and even burned.
In theory, lump coal, pulverized coal, oil or gas burning devices can burn biomass fuels, but due to the unique combustion characteristics of biomass materials, there are still many problems in burning biomass fuels in these biomass burners, such as pulverized coal. When it is burned in a dry state, it should first be made into powder, but because biomass fuel is a non-brittle material, it is easy to form fiber clusters instead of powder during grinding, and it needs to be dried in advance, while drying high-moisture biomass fuels requires a lot of consumption hot. Therefore, some combustion devices (also known as biomass burners) have been developed for the characteristics of biomass fuels.
The following biomass burner manufacturers briefly introduce these combustion devices to you:
1. Biomass fuel stratified combustion device: adopts the same form of stratified combustion device as lump coal
2. Biomass fuel fluidized bed combustion device: The fluidized bed reactor has the advantages of uniform mixing, large heat and mass transfer coefficients, high combustion efficiency, less harmful gases, easy control of the process, and high reaction capacity. Therefore, the fluidized bed is used Reactor chemical treatment of biomass is becoming more and more popular.
3. Biomass fuel diffusion combustion device: use mechanical power or wind to disperse the crushed biomass fuel (rice husk, finely chopped straw, etc.), and then burn it in the air. This kind of furnace has sufficient contact between biomass fuel and air in the combustion chamber, so the combustion is complete and the temperature is relatively stable.
