[Abstract]Biomass fuel is burning biomass materials as fuel, the main raw materials is the agriculture and forestry waste as raw materials.Straw briquette fuel (BiomassMouldingFuel,referred to as"BMF"), is using the agriculture and forestry waste as raw material, after crushing,mixing, extrusion, and drying process,making into a variety of molding,(such as the massive, granular, etc.),it is a new type of clean fuel for combustion which can be used directly. But how to use safely and reliabliy,our country has not mature technology now.This article detailed introduced the author through the method by cooperating with the enterprise to design a biomass fuel controller design scheme based on PLC.
