The general characteristics of condensing boiler burners are high moisture content, low ash content, high volatile content, low calorific value, and irregular shape. ) can be directly burned, other fuels such as straw, branches, etc. must be treated before burning to enable cloth and ensure uniform burning.

In theory, lump coal, pulverized coal, oil or gas combustion 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 biomass. When it is burnt, it should be made into powder first, but because biomass fuel is a non-brittle material, it is easy to generate fibrous mass instead of powder during grinding, and it needs to be pre-dried, while drying high-moisture biomass fuel requires a lot of consumption. hot. Therefore, some combustion devices (aka biomass burners) are currently developed for the properties of biomass fuels.

The following condensing boiler burner manufacturer Zhongli Weiye Energy Saving briefly introduces these combustion devices to you:

1. Biomass fuel layered combustion device: adopt the layered combustion device in the same form 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 process control, and high reaction capacity. Therefore, the use of fluidized bed Reactors are increasingly popular for chemical processing of biomass.

3. Biomass fuel diffusion combustion device: use mechanical power or wind power to disperse the crushed biomass fuel (rice husk, finely crushed straw, etc.), and then burn in the air. This kind of furnace burns completely and the temperature is relatively stable due to the sufficient contact between biomass fuel and air in the combustion chamber.
