Abstract
本实用新型为热汽联产燃煤空气炉，解决已有空气炉功能单一，耗能高，使用寿命短的问题。沸腾锅炉(3)的燃烧室有进料口与喂煤机(1)相通，有进风口与鼓风机(2)相通，燃烧室产生的高温烟气与锅炉本体(9)进行了热交换生产的蒸汽从锅炉本体导出，冷却的烟气经管道进入空气换热器(4)与鼓风机(5)鼓入的空气换热，加热后的空气从空气换热器排出供用户，换热后烟气经管道进入旋风除尘器(6)，除尘后烟气经引风机(7)送入排气筒(8)排空。
The utility model is a coal-fired air furnace for cogeneration of heat and steam, which solves the problems of single function, high energy consumption and short service life of the existing air furnace. The combustion chamber of the fluidized boiler (3) has a feed port connected to the coal feeder (1), an air inlet connected to the blower (2), and the high-temperature flue gas produced in the combustion chamber is produced by heat exchange with the boiler body (9). The steam is exported from the boiler body, the cooled flue gas enters the air heat exchanger (4) through the pipe to exchange heat with the air blown by the blower (5), the heated air is discharged from the air heat exchanger for the user, and the flue gas after heat exchange Enter the cyclone dust collector (6) through the pipe, and the flue gas after dust removal is sent to the exhaust pipe (8) through the induced draft fan (7) to be emptied.
Description
Technical field:
The utility model is relevant with the combustion apparatus that fluid bed is arranged.
Background technology
In industrial production, usually need to supply simultaneously steam and hot air cleaning.Present most enterprise adopts 1 boiler supplying steam, and another interstation connects the hot-blast stove supply hot air cleaning of heating.The equipment investment height, the thermal efficiency is low, the environmental pollution height.The air distribution plate perforate of boiling boiler is unreasonable, easily causes coal-fired coking, causes blowing out.
The utility model content:
The purpose of this utility model provide a kind of cheap, the thermal efficiency is high, boiling boiler is difficult for coking, long service life, can produce the coal-fired air furnace of heating and steam combined generating of saturated vapor and hot air cleaning simultaneously.
The utility model is achieved in that
The combustion chamber of boiling boiler 3 has charging aperture to communicate with coal feeder 1, there is air inlet to communicate with air blast 2, high-temperature flue gas that the combustion chamber produces and boiler body 9 have carried out the steam of heat exchange production derives from boiler body, the flue gas of cooling enters the air heat exchange that air heat exchanger 4 and air blast 5 blast through pipeline, air after the heating is discharged for the user from air heat exchanger, flue gas enters cyclone dust collectors 6 through pipeline after the heat exchange, and flue gas is sent into aiutage 8 emptyings through air-introduced machine 7 after the dedusting.
Percent opening 〉=2～6% of the air distribution plate 9 in the combustion chamber of boiling boiler, the layout density of blast cap 10 are 200-250/m
2
Air blast 2 blasts the combustion chamber of boiling boiler 3 and coal grain with air and meets and burn, and produces high-temperature flue gas, carries out indirect heat exchange by boiler body and produces steam.The flue gas of part cooling enters air heat exchanger 4 and the free air indirect heat exchange that air-blaster 5 blasts again, obtains hot air cleaning.Leng Que flue gas is sent into aiutage 8 emptyings by air-introduced machine 7 after cyclone dust removal 6 once again.
The utility model thermal efficiency height, cost is low, reduced investment, function is many, and is easy to operate, and power consumption is few, and environmental pollution is few.Because the perforate of air distribution plate is reasonable, coal combustion is abundant, is difficult for coking, the boiling boiler long service life.But the utility model burning inferior coal; Open, blowing out is convenient; Hot air temperature is stable; Environmental pollution is little; Thermal efficiency height; Low, the reduced investment of cost.

Fig. 3 is the vertical view of Fig. 2.
The specific embodiment:
Below be embodiment of the present utility model:
The coal grain enters the combustion chamber of boiling boiler 3 through coal feeder 1 and elephant trunk, and the air that blasts with air blast 2 meets and burns.Produce 850～950 ℃ high-temperature flue gas, the saturated vapor that produces 1.25MPa with the boiler body heat exchange that is provided with in the boiler is given the user.Temperature is that flue gas about 500 ℃ enters the air indirect heat exchange that air heat exchanger 4 and air-blaster 5 blast after the heat exchange, gives the user with about 10-30 ℃ air heat to 350 ℃.
Temperature is 150～180 ℃ a flue gas after the heat exchange, after efficient cyclone separator 6 dedustings, sends into emptying in the aiutage 8 by air-introduced machine 7.
Claims (2)
1. the coal-fired air furnace of heating and steam combined generating, the combustion chamber that it is characterized in that boiling boiler (3) has charging aperture to communicate with coal feeder (1), there is air inlet to communicate with air blast (2), high-temperature flue gas that the combustion chamber produces and boiler body (9) have carried out the steam of heat exchange production derives from boiler body, the flue gas of cooling enters the air heat exchange that air heat exchanger (4) and air blast (5) blast through pipeline, air after the heating is discharged for the user from air heat exchanger, flue gas enters cyclone dust collectors (6) through pipeline after the heat exchange, and flue gas is sent into aiutage (8) emptying through air-introduced machine (7) after the dedusting.
