Description
Technical field
The utility model relates to a kind of boiler, particularly relates to a kind of biomass energy-saving and reduces discharging stove.
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
the utility model is exactly the problem that exists for the said goods, provide a kind of biomass energy-saving to reduce discharging stove, solving the said goods exists biomass fuel can produce to the heating surface of burner deposition and corrosion in burning, 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, living beings are perishable heating surface in burning, water jacket in burner hearth also easily produces drainage, cause maintenance to delay work, maintenance cost is high, there is the biomass boiler combustion temperature in hearth of water jacket to reduce, the thermal efficiency reduces, waste energy, strengthened smoke discharge amount, contaminated environment.Water jacket in burner hearth easily produces incrustation scale, conduct heat bad, make evaporation capacity reduce, reduce boiler output, the living beings burner hearth easily is burned, produce drainage, cause maintenance, maintenance cost high, easy slagging scorification in the biomass fuel combustion process, affect efficiency of combustion and boiler output, shorten the problems such as service life of boiler.
the utility model adopts following technical scheme: a kind of biomass energy-saving reduces discharging stove, comprise the first water jacket (1), chimney (2), panel (3), kitchen range mouth (4), the second water jacket (5), the 3rd water jacket (6), body of heater (7), refractory material (8), backwater cover (9), living beings burner hearth (10), secondary wind distributing hole (11), ash chamber and a wind entrance (12), the 4th water jacket (13), establish chimney (2) above the first water jacket (1), sidewall respectively with the second water jacket (5), the 3rd water jacket (6) communicates, the second water jacket (5) upper sheathing plate (3), panel (3) is established kitchen range mouth (4) with middle perforation of the second water jacket (5), also mate with it kitchen range mouth (4) symmetry in the middle of symmetrical the 3rd water jacket (6) and establish living beings burner hearth (10) mouth, living beings burner hearth (10) mouth is established secondary wind distributing hole (11), build refractory material (8) by laying bricks or stones between living beings burner hearth (10) periphery and body of heater (7), the first water jacket (1), the second water jacket (5), the 3rd water jacket (6), backwater cover (9), the 4th water jacket (13) is connected, boiler internal heating surface material is the NiCrMoSiB alloy.
The utility model compared with prior art has following beneficial effect: described a kind of biomass energy-saving reduces discharging stove, and burner hearth is without water jacket, be difficult in burner hearth being burned, do not have water leakage, do not produce incrustation scale, be difficult for to stop up, maintenance, maintenance cost are low, are difficult for producing the infiltration phenomenon, reduced the resistance of water circulation, improved the ignition temperature in burner hearth, made biomass fuel combustion abundant, the thermal efficiency is high, save the energy, reduced smoke discharge amount, effectively environmental protection.Double-layer water jacket is established in the burner hearth upper end, increased the heating surface of biomass boiler, deposition and corrosion that biomass fuel produces the heating surface of burner have been reduced simultaneously in burning, stockhole is established the secondary wind distributing hole, make the sufficient while of biomass fuel combustion, reduced the generation of slagging scorification, the prolonged boiler life-span.
