Abstract
The utility model discloses a biomass hearth water-jacket-free boiler. The biomass hearth water-jacket-free boiler comprises a first water jacket (1), a smoke tube (2), a panel (3), a cooker mouth (4), a second water jacket (5), a third water jacket (6), a boiler body (7), a fireproof material (8), a backwater jacket (9), a biomass hearth (10) and a fourth water jacket (11), wherein the first water jacket (1) is provided with the smoke tube (2), and the side wall of the first water jacket (1) is respectively communicated with the second water jacket (5) and the third water jacket (6); the second water jacket (5) is covered by the panel (3); the cooker mouth (4) is formed in the middle of the panel (3) and the second water jacket (5) in a through manner; a mouth of the biomass hearth (10), matched with the cooker mouth (4), is symmetrically arranged in the middle of the third water jacket (6) which is symmetrical to the panel (3) and the second water jacket (5); the fireproof material (8) is built between the periphery of the biomass hearth (10) and the boiler body (7); the first water jacket (1), the second water jacket (5), the third water jacket (6), the backwater jacket (9) and the fourth water jacket (11) are mutually communicated, and the heated surface in the boiler is made of nickel chromium molybdenum silicon boron (NiCrMoSiB) alloy.
Description
Technical field
The present invention relates to a kind of boiler, particularly relate to the anhydrous cover boiler of a kind of living beings burner hearth.
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, shorten the service life of boiler.
Summary of the invention
the present invention is exactly the problem that exists for the said goods, provide a kind of living beings burner hearth anhydrous cover boiler, 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, conducts heat bad, makes evaporation capacity reduce, reduce boiler output, shortens the problems such as service life of boiler.
the present invention adopts following technical scheme: the anhydrous cover boiler of a kind of living beings burner hearth, 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), the 4th water jacket (11), 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, 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 (11) is connected, boiler internal heating surface material is the NiCrMoSiB alloy.
The present invention compared with prior art has following beneficial effect: the anhydrous cover boiler of described a kind of living beings burner hearth has improved the ignition temperature of burner hearth, sufficient combustion, and the thermal efficiency is high, saves the energy, has reduced smoke discharge amount, comparatively environmental protection.Simultaneously burner hearth is due to without water jacket, reduced deposition and corrosion that biomass fuel produces the heating surface of burner in burning, is difficult for producing the infiltration phenomenon, and maintenance cost, recondition expense are low, are difficult for producing incrustation scale, have reduced the resistance of water circulation, the prolonged boiler life-span.
Description of drawings
Fig. 1 is structural representation of the present invention.
