What are the reasons why biomass boilers can be vigorously promoted?

23 Mar, 2022

　　Biomass boilers have received more and more attention. The fundamental reasons why biomass boilers have been vigorously promoted:

　　(1) The carbon content is less. The highest carbon content in biomass fuel is only about 50%, and the calorific value is low.

　　(2) The hydrogen content is slightly more. There are obviously more volatiles, and most of the carbon in biomass is combined with hydrogen to form low-molecular hydrocarbons, which are thermally decomposed to a certain temperature to precipitate volatiles, so biomass fuels are easy to ignite.

　　(3) The oxygen content is high. The oxygen content of biomass fuel is significantly more than that of coal, which makes biomass fuel low in calorific value.

　　(4) The density is small. The density of biomass fuel is obviously lower than that of coal, the texture is looser, and it is easy to burn out.

　　(5) Low sulfur content. The sulfur content of biomass fuel is mostly less than 0.12%, and the boiler does not need to be equipped with a desulfurization device.

　　(6) The CO2 released by biomass is very low, which can be considered as zero CO2 emission.

　　(7) The ash after biomass combustion can be used to manufacture fertilizers.

　　(8) Biomass can be mixed with coal to improve the combustion efficiency (note that the direct combustion of biomass fuel and the co-firing of biomass and coal are absolutely avoided in the current comprehensive atmospheric control actions, commonly referred to as the promotion of biomass Substance boiler refers specifically to clean energy boiler equipment burning biomass briquette fuel).

　　(9) The use of biomass burning can realize the reduction, harmlessness and resource utilization of biomass waste.
