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 the base 8, and drum 16 is fixed on boiler steelframe 11 tops.Build refractory brick 9, the lower boiler furnace upper drum integrative-structure of outer building heat-insulation brick 10 formation in around the boiler steelframe 11 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 directly is not heated is built on the top by laying bricks or stones, the combustion chamber 4 of being furnished with air distribution door 6 on the base 8 and forming, 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 the combustion chamber 4.The first half and Lower Half in the described drum 16 all are equipped with one group of smoke pipe 18, establish heat insulation aerofoil 17 between one group of smoke pipe of the first half and one group of smoke pipe of Lower Half.Described drum section is provided with air inlet 13 and hot wind outlet 12, and cold wind is entered in the drum 16 by air inlet 13 and forms hot blast from hot wind outlet 12 to the hot wind supply place with smoke pipe 18 heat exchanges.Low-temperature flue gas after the heat exchange in the 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 consisted of moulded coal hot blast environment-protection boiler.
The present invention utilizes the solid charcoal of moulded coal admittedly to flow non-smoke combustion technique, and the technology that change moulded coal charcoal boiler is only limited to aspect hot-water boiler is used.The present invention meets environmental requirement and the social demand of country, it is reasonable that main innovation and creation provide a kind of design science, the hot air boiler that the drum of burner hearth and the cylinder bundle that is heated becames one, compact conformation, attractive in appearance beautiful, the thermal efficiency is high, stable, safe and reliable, energy-conserving and environment-protective, the boiler room floor space is little, applicability is strong leading technology product.It mainly invents the place is that the unmodifiable spontaneous firing phenomenon of molded coal boiler is constant temperature combustion heating in 24 hours.Even adjust the deep bead that air door is closed chimney, fuel in the burner hearth is also in little fiery state burning, temperature in the burner hearth is also higher, if do not open in the untimely exchanging air tube bank that enters drum of blower fan cold wind, chimney is easy to be burned distortion or burns the smoke pipe tube bank.Substantially be two body structures in design according to the domestic moulded coal hot air boiler of the combustion characteristics of moulded coal (honeycomb briquette), namely (burner hearth and the drum tube bundle heat exchanger that is heated are separately, its unreasonable structure, the waste raw material, heat loss is large, the thermal efficiency is low, the floor space of boiler room is large, and the present invention has changed the un-reasonable phenomenon that domestic moulded coal hot air boiler in the past is divided into two body structures, can also save the fund input that the boiler room is built to the user.
Main innovate point of the present invention is with the burner hearth of boiler and is heated and restrains the moulded coal hot blast environment-protection boiler that drum becames one, burner hearth is lower, the drum that is heated tube bank is upper, the fire-resistant furnace wall in lower hearth both sides adopts the fireproof high-temperature resistant brick masonry, roof of the furnace is built with thermostable high-alumina cement and is formed an arc plagioclase arch, sealing all around, the refractory wall of both sides forms the secondary cigarette channel of a hearth-type with laying fireproof bricks in the middle of plagioclase arch and drum heat exchanger.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 distance of the flame travel in the burner hearth is effectively increased.Fire smoke gases in the burner hearth enters swimmingly secondary cigarette burner hearth by lower hearth and enters the tube bank of being heated again.Flame in the thorax can not direct contact heat transfer device drum under any situation the bottom.Flame in the burner hearth more can not contact the smoke pipe of the tube bank of being heated, the tube bank of being heated of two backhauls of design in the upper drum heat exchanger, the amount of heat that produces in the body of heater fully is heated and produces a large amount of nonpoisonous and tasteless clean airs to the hot place of using after blower fan enters heat exchanger, flue gas is discharged body of heater swimmingly, under any situation also not can chimney be heated the 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, close down timely, open blower fan according to the temperature of burner hearth and hot blast and more can effectively save power consumption cost in the boiler operatiopn.
