Description

A kind of biomass low-carbon energy-saving boiler

Technical field

The utility model relates to a kind of boiler, particularly relates to a kind of biomass low-carbon energy-saving boiler.

Background technology

after PM2.5 lists national standard in, Area Ambient Air Quality problem up to standard is faced with baptism, especially the Air–pollution From Combustion environment of fossil fuel is unfavorable for energy-conserving and environment-protective, biomass boiler comes into one's own gradually and extensively utilizes as a kind of productive life equipment of environmental protection and energy saving, the burner hearth of existing biomass boiler is mostly with water jacket, reduced the ignition temperature of burner hearth, burn insufficient, cause the thermal efficiency to reduce, strengthened smoke discharge amount, simultaneously due to living beings burner hearth hot soak condition, biomass fuel heating surface to burner in burning produces deposition, deposition can be with the prolongation progressive additive of production time, the heat exchange order is progressively reduced, can cause heat exchanger tube to destroy when serious, leak, interrupt normal operation.Although there is difference the time that this phenomenon occurs, all can occur if deal with nearly all equipment improperly.Living beings perishable heating surface in burning in addition, water jacket in burner hearth also easily produces drainage, cause maintenance to delay work, the problem that maintenance cost is high, burner hearth has water jacket also easily to produce incrustation scale simultaneously, the heating surface heat exchange is worse off, increases exhaust gas temperature, reduce boiler thermal output, waste fuel.Bad owing to conducting heat, make evaporation capacity reduce, reduce boiler output.If fouling in water pipe, actual internal area reduces, and has increased the flow resistance of water circulation, pipe can be stopped up fully when serious, destroys normal water circulation, causes pipe explosion accident.Need frequent blowing out to clean during scale removal, increase recondition expense, often adopt machinery and Clearing up scales with a chemical method that heating surface is sustained damage, moreover in the biomass fuel combustion process, easily slagging scorification, affect efficiency of combustion and boiler output, shortens the service life of boiler.

Summary of the invention
