Description
Technical field
The present invention relates to a kind of boiler, particularly relate to a kind of living beings multilayer water jacket boiler.
Background technology
After PM2.5 listed national standard in, urban environment air quality problem up to standard was faced with baptism, and especially the Air environment of fossil fuel is unfavorable for energy-conserving and environment-protective; Biomass boiler comes into one's own and extensively utilization as a kind of productive life equipment of environmental protection and energy saving gradually, and the burner hearth of prior biological matter boiler has water jacket mostly, has reduced the ignition temperature of burner hearth; It is insufficient to burn, and causes the thermal efficiency to reduce, and has strengthened smoke discharge amount; Owing to living beings burner hearth hot soak condition, biomass fuel heating surface to burner in burning produces deposition simultaneously, and 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 normally operation.Though there is difference the time that this phenomenon occurs, all can take place if deal with nearly all equipment improperly.Living beings perishable heating surface in burning in addition; Water jacket in the burner hearth also is easy to generate drainage, causes maintenance to delay work the problem that maintenance cost is high; Burner hearth has water jacket also to be prone to produce incrustation scale simultaneously; The heating surface heat exchange is worse off, increases exhaust gas temperature, reduce boiler thermal output, waste fuel.Because it is bad to conduct heat, make evaporation capacity reduce, reduce boiler output.If fouling in the water pipe, actual internal area reduces, and has increased the flow resistance of water circulation, can pipe 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 chemical method scale removal meeting that heating surface is sustained damage, shorten the service life of boiler.
Summary of the invention
The present invention is exactly the problem that exists to the said goods, and a kind of living beings multilayer water jacket boiler is provided, and solves the said goods and exists biomass fuel in burning, can produce deposition and corrosion to the heating surface of burner, and 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 normally operation; Living beings are perishable heating surface in burning, and the water jacket in the burner hearth also is easy to generate drainage, causes maintenance to delay work; Maintenance cost is high, has the biomass boiler combustion temperature in hearth of water jacket to reduce, and the thermal efficiency reduces; Waste energy, strengthened smoke discharge amount, contaminated environment.Water jacket in the burner hearth is prone to produce incrustation scale, and it is bad to conduct heat, and makes the evaporation capacity reduction, reduces boiler output, and the living beings burner hearth is prone to burnt out, and produces drainage, causes maintenance, maintenance cost height, shortens the problems such as service life of biomass boiler.
The present invention adopts following technical scheme: a kind of living beings multilayer water jacket boiler; Comprise water jacket (1), chimney (2), panel (3), kitchen range mouth (4), water jacket (5), water jacket (6), water jacket (7), body of heater (8), refractory material (9), backwater cover (10), living beings burner hearth (11), water jacket (12); Establish chimney (2) above the water jacket (1); Sidewall communicates with water jacket (5), water jacket (6), water jacket (7) respectively, water jacket (5) upper sheathing plate (3), and panel (3) is established kitchen range mouth (4) with middle perforation of water jacket (5); Also mate kitchen range mouth (4) symmetry with it in the middle of the water jacket (6) of symmetry, the water jacket (7) and establish living beings burner hearth (11) mouth; Build refractory material (9) by laying bricks or stones between living beings burner hearth (11) periphery and the body of heater (8), water jacket (1), water jacket (5), water jacket (6), water jacket (7), backwater cover (10), water jacket (12) are connected, and living beings burner hearth (11) the upper water sleeve number of plies is more than three layers or three layers; Refractory material (9) is refractory cement and fire-resistant sand, and boiler internal heating surface material is the NiCrMoSiB alloy.
The present invention compared with prior art has following beneficial effect: said a kind of living beings multilayer water jacket boiler, and burner hearth does not have water jacket, is difficult for producing the infiltration phenomenon; Maintenance cost, recondition expense are low, are difficult for producing incrustation scale, have reduced the resistance of water circulation; Improved the ignition temperature in the burner hearth, made biomass fuel combustion abundant, the thermal efficiency is high; Save the energy, reduced smoke discharge amount, effectively environmental protection.Establish three layers of water jacket above the living beings burner hearth, increased the heating surface of biomass boiler, reduced deposition and corrosion that biomass fuel produces the heating surface of burner simultaneously in burning, the prolonged boiler life-span.
