Technical field
The utility model relates to a kind of biomass steam boilers.
Background technique
China has Industrial Boiler ten thousand about more than 50 at present, and annual coal consumption is about the 1/3 of national coal consumption total amount, due to fire coal
Environmental pollution caused by Industrial Boiler is very serious, and a large amount of Industrial Boiler must use clear energy sources instead.According to the biology in China
Matter resources supplIes, are used using forest and agricultural biomass as boiler oil, have the characteristics that it is environmental-friendly, can regenerate, study work
Industry boiler biomass combustion technology develops biomass fuel boiler, to conventional energy resource, optimization China's energy resource structure is saved, mitigates
Environmental pollution has positive effect.
Biomass boiler is a type of boiler, is exactly the boiler using biomass energy as fuel biomass pot
Furnace is divided into biomass steam boiler, biomass hot water boiler, biomass thermal wind furnace, biomass heat-conduction oil oven, vertical type biomass pot
Furnace, horizontal biomass boiler etc..Biomass fuel used by biomass boiler, which refers to, regard biological material burning as fuel,
Generally mainly agriculture and forestry organic waste material (such as stalk, sawdust, bagasse, rice chaff), these biomass typically contain higher moisture,
If biggish damage can be caused to boiler by directly carrying out burning in the boiler, but if in addition dehumidify cost before burning again
Higher, therefore, the moisture problem of biomass always affects the popularization and application of biomass boiler.
