Production description
A biomass steam boiler uses biomass fuels, such as agricultural and forestry waste, as its primary energy source, generating steam through combustion. Its main structure consists of the boiler body (responsible for heating softened water) and the furnace (responsible for fuel combustion). It utilizes an automatic feeding system and variable frequency control technology for automated operation. Its diverse and renewable fuel sources, low operating costs, and environmental friendliness make it widely used in industries such as heating, chemicals, food, and textiles.
