Description

Vertical normal pressure overheat steam boiler

The utility model relates to a kind of combustion apparatus, especially for a kind of vertical normal pressure overheat steam boiler that needs the high-temperature steam occasion.

Existing normal-pressure hot-water boiler can satisfy the common needs of heating up water and warming oneself, but to carrying out disinfection with high-temperature steam, can not being met fully during special requirement such as Saunas, fabrics printing and dyeing, wine brewing.Therefore, steam superheater is installed by the boiler for producing producer that has in boiler, utilizes boiler afterheat to produce steam, makes multi-use.But because existing boiler is that steam superheater is installed in the hyperthermia radiation heat affected zone of lower furnace portion, steam superheater is very easily burnt out, also increased the fractional cold in the burner hearth, make burning of coal insufficient, because the burner hearth clean-burning place that is coal, heating surface is arranged too many, and is unfavorable to burning of coal; Simultaneously, steam superheater and boiler erection connect as one, and the dismounting maintenance is extremely inconvenient.

The purpose of this utility model is to provide a kind of installation site of steam superheater reasonable, convenient disassembly, and long service life can improve the vertical normal pressure overheat steam boiler of boiler thermal output.

Technical solution of the present utility model is: comprise body of heater 16, in courage 17, lower combustion chamber 2 in being located in the courage 17, water-cooled grate 3, upper combustion chamber 4, moving grate 19, be connected with moving grate 19 remove 1 and be located in the lower smoke box 5 at courage 17 middle parts, the Heat Room 6 on top, with Heat Room 6 and last, the up smoke pipe 12 that lower combustion chamber is communicated with, descending smoke pipe 13 that is communicated with lower smoke box 5 and Heat Room 6 and boiler venthole 10, it is characterized in that in Heat Room 6, being equipped with steam superheater 7, its arrival end is communicated with boiler venthole 10 by boiler steam outlet pipe 9, and the port of export is communicated with subscriber equipment.

In this programme, steam superheater 7 is made of saturated vapor inlet tube 72, superheated steam outlet 71, upper strata comb 73, lower floor's comb 75 and descending tube connector 74, wherein, saturated vapor inlet tube 72 and superheated steam outlet 71 are connected with lower floor comb 75 with upper strata comb 73 respectively, upper strata comb 73 and lower floor's comb 75 link into an integrated entity by descending tube connector 74, saturated vapor inlet tube 72 is communicated with boiler venthole 10 by boiler steam outlet pipe 9, and superheated steam outlet 71 is communicated with subscriber equipment.

Advantage of the present utility model is: because steam superheater is installed in the Heat Room of upper boiler, can fully absorb the waste heat in the Heat Room, the steam of generation about up to 200 ℃, accomplish multi-use, and not fragile steam superheater, also can reduce the exhaust gas temperature of boiler, save the energy, improve boiler thermal output; Simultaneously, in the utility model, steam superheater is connected to the opening part of Heat Room by flange, and is provided with capping at opening part, both for convenience detach, make Heat Room reach the better seal effect again, reduce heat loss.

Following accompanying drawing has been described embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A profile of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in detail.As shown in the figure, the utility model is provided with body of heater 16 and lining courage 17, is provided with water-cooled grate 3 in lining courage 17, water-cooled grate 3 can be made of one deck fire grate, also can be by parallel two layers or parallel three layers of fire grate are staggered up and down constitutes, in this programme, water-cooled grate 3 constitutes by three layers of parallel fire grate are staggered up and down, be staggered like this, can be heated better, and flue gas is burnt once more, can eliminate black smoke simultaneously, improve the grate temperature of water-cooled grate, increase burning velocity.Water-cooled grate 3 is divided into upper combustion chamber 4 and lower combustion chamber 2 with the combustion chamber, is respectively equipped with shoot door 14 and shoot door 18 in upper combustion chamber 4 and the lower combustion chamber 2.In the bottom of courage 17 be provided with moving grate 19, ash-falling chamber 20, ash-falling chamber's shoot door 21, moving grate 19 is provided with to be removed 1, as long as close fire door during deashing, moves and just the dust stratification on the fire grate can be disposed 1, not only health but also reduce fireman's labour intensity.In the middle part of courage 17 be provided with lower smoke box 5, top is provided with Heat Room 6, the top of up smoke pipe 12 is communicated with Heat Room 6, the lower end is communicated with upper and lower combustion chamber, the top of descending smoke pipe 13 is communicated with Heat Room 6, the lower end is communicated with lower smoke box 5.The boiler top is provided with boiler venthole 10, manhole 11, and Heat Room 6 is provided with Heat Room shoot door 61.In order to make the utility model can satisfy steam user's needs, make full use of the waste heat in the Heat Room 6, steam superheater 7 is installed in Heat Room 6, be provided with boiler steam outlet pipe 9 between steam superheater 7 and the boiler venthole 10, the arrival end of steam superheater 7 is communicated with boiler venthole 10 by boiler steam outlet pipe 9, and the port of export of steam superheater 7 is communicated with subscriber equipment.Steam superheater 7 can be made of the individual layer comb, also can adopt the double-deck comb of upper intake lower outlet type or three layers of calandria structure, in the present embodiment, adopt double-deck calandria structure, promptly constitute steam superheater 7 by saturated vapor inlet tube 72, superheated steam outlet 71, upper strata comb 73, lower floor's comb 75 and descending tube connector 74.Wherein, saturated vapor inlet tube 72 and superheated steam outlet 71 are connected with lower floor comb 75 with upper strata comb 73 respectively, upper strata comb 73 and lower floor's comb 75 link into an integrated entity by descending tube connector 74, saturated vapor inlet tube 72 is communicated with boiler venthole 10 by boiler steam outlet pipe 9, and superheated steam outlet 71 is communicated with subscriber equipment.During operation, the normal pressure saturated vapor that boiler produces is delivered in the saturated vapor inlet tube 72 of steam superheater 7 through boiler steam outlet pipe 9 by boiler venthole 10, enters the back that is heated in the upper strata comb 73 and enters into lower floor's comb 75 to the rear end through descending tube connector 74 and wash away and enter into subscriber equipment through the superheated steam outlet 71 of front end again after being heated.During installation, perforate on Heat Room, the steam superheater 7 of packing into thus passes capping 8, is communicated with boiler steam outlet pipe 9 by flange.This kind mounting means had been both simple, be convenient to dismounting, made Heat Room reach the better seal effect again, reduced heat loss.In existing boiler, steam superheater is installed, is not added any heat-conducting medium, utilize boiler afterheat, the saturated vapor about 100 ℃ can be heated into the superheated steam about 200 ℃, both satisfied steam user's needs.Reduce exhaust gas temperature again, improved the thermal efficiency.Steam superheater can be contained in the Heat Room of vertical boiler of various structures.In the utility model, steam superheater adopts exotic material, long service life.
