The reason why the biomass boiler is clean and environmentally friendly is that the fuel it uses is biomass particulate fuel. This fuel is made by processing agricultural and forestry straw waste, and it burns clean without pollution. It has the advantages of environmental protection, energy saving and cost saving; while the fuel used for coal-fired boilers is a certain kind of charcoal, which generates a large amount of dust, sulfur oxides and nitrogen oxides during use. The state has explicitly banned direct emissions.

In terms of the structure of the boiler: the biomass furnace is equipped with an automatic feeding device and an automatic ignition device. Compared with a coal furnace, it can reduce the personnel expenses of the boiler operator.

Biomass currently belongs to boilers to be promoted, and small coal stoves are already obsolete products.

Boiler combustion emissions. Biomass boilers burn biomass particulate fuel and have fewer polluting pollutants, so they have a higher environmental advantage; while coal-fired boilers emit more polluting gases, causing great environmental pollution and ecological damage.

It is well known that biomass boilers use agricultural and forestry straw waste as fuel and burn clean and pollution-free, while coal-fired boilers use ore fuel coal as fuel and generate more dust, sulfur oxides and nitrogen oxides during use. Biomass boilers have the characteristics of direct emission without smoke, slagging, and corrosion, while coal-fired boilers have large smoke pollution, insufficient combustion and large waste, and do not save energy and protect the environment. Biomass boiler has better durability, stability and energy saving.
