The specific embodiment
Moulded coal hot blast environment-protection boiler, comprises base 8, boiler steelframe 11, combustion chamber 4, drum 16, lever gear door 1.Described boiler steelframe 11 is fixed on base 8, and drum 16 is fixed on boiler steelframe 11 tops.In boiler steelframe 11 surroundings, build refractory brick 9, the lower boiler furnace upper drum integrative-structure of outer building heat-insulation brick 10 formation by laying bricks or stones, described boiler furnace Inner Front End is built front arch wall 2 by laying bricks or stones, the refractory heat-insulating wall 3 that drum is not directly heated is built on top by laying bricks or stones, on base 8, be furnished with air distribution door 6 and combustion chamber 4, combustion chamber 4 front ends are provided with lever gear door 1, are provided with the plagioclase arch wall 5 of balance flue-gas temperature in combustion chamber 4.The first half in described drum 16 and Lower Half are all provided with one group of smoke pipe 18, between one group of smoke pipe of the first half and one group of smoke pipe of Lower Half, establish heat insulation aerofoil 17.Described drum portion is provided with air inlet 13 and hot wind outlet 12, and cold wind is entered in drum 16 and formed hot blast with smoke pipe 18 heat exchanges by air inlet 13, and hot blast offers hot blast place from hot wind outlet 12.Low-temperature flue gas after heat exchange in smoke pipe is discharged through chimney 14.Described combustion chamber 4 rear sides are provided with skimming door 7; The rear end on 4 tops, combustion chamber is provided with shoot door 15, and drum 16 front ends are provided with smoke pipe shoot door 19, has describedly formed moulded coal hot blast environment-protection boiler.
The utility model is to utilize the solid charcoal of moulded coal admittedly to flow non-smoke combustion technique, changes moulded coal charcoal boiler and is only limited to the technology application aspect hot-water boiler.The utility model meets national environmental requirement and social demand, main utility model creates that to be to provide a kind of design science reasonable, a hot air boiler that burner hearth and the drum of the cylinder bundle that is heated became one, compact conformation, attractive in appearance beautiful, the thermal efficiency is high, stable, safe and reliable, energy-conserving and environment-protective, boiler room floor space is little, applicability is strong leading technology product.Its main utility model place is that the unmodifiable spontaneous firing phenomenon of molded coal boiler is constant temperature combustion heating in 24 hours.Even adjustment air door is closed the deep bead of chimney, fuel in burner hearth is also in little fiery state burning, temperature in burner hearth is also higher, if do not opened in the exchanging air tube bank that enters drum not in time of blower fan cold wind, chimney is easy to be burned distortion or burns smoke pipe tube bank.According to the domestic moulded coal hot air boiler of the combustion characteristics of moulded coal (honeycomb briquette), be two body structures in design substantially, (burner hearth and the drum tube bundle heat exchanger that is heated are separately, its unreasonable structure, waste raw material, heat loss is large, the thermal efficiency is low, the floor space of boiler room is large, and the utility model has changed the un-reasonable phenomenon that domestic moulded coal hot air boiler is in the past divided into two body structures, can also save the fund input that boiler room is built to user.
Main innovate point of the present utility model is the moulded coal hot blast environment-protection boiler that the burner hearth of boiler and the tube bank drum that is heated are became one, burner hearth under, the drum that is heated is restrained upper, the fire-resistant furnace wall in lower hearth both sides adopts fireproof high-temperature resistant brick masonry, roof of the furnace is built and is formed an arc plagioclase arch with thermostable high-alumina cement, surrounding sealing, in the middle of plagioclase arch and drum heat exchanger, the refractory wall of both sides forms the secondary cigarette channel of a hearth-type with laying fireproof bricks.The top of secondary cigarette channel is built top seal with high temperature resistant high-temperature cement bauxites aggregate heat exchanger boiler drum bottom and high temperature convection temperature and hyperthermia radiation temperature isolation is left, tail end lower hearth and secondary cigarette channel place at boiler arrange that a lower hearth smoke-refeed mouth makes the flame of lower hearth enter secondary cigarette burner hearth, and the flame travel distance in burner hearth is effectively increased.Fire smoke gases in burner hearth enters swimmingly secondary cigarette burner hearth by lower hearth and enters the tube bank of being heated again.Flame in thorax can not direct contact heat transfer device drum under any situation bottom.Flame in burner hearth more can not contact the smoke pipe of the tube bank of being heated, in upper drum heat exchanger, design the tube bank of being heated of two backhauls, the amount of heat producing in body of heater is fully heated and after blower fan enters heat exchanger, produces a large amount of nonpoisonous and tasteless clean airs to the hot place of using, flue gas is discharged body of heater swimmingly, under any situation also not can chimney be heated tube bank boiler drum bottom burn, fundamentally solved the difficult problem that integral type moulded coal hot air boiler easily burns smoke pipe.At power distribution control system configuration temperature controller, according to the temperature of burner hearth and hot blast, close down timely, open blower fan and more can effectively save the power consumption cost in boiler operatiopn.
