The tubular boiler is safe and reliable, and is scientific and compact in structure, fast in pressure rising and high in efficiency.
Description
Technical field
The utility model relates to a kind of tubular boiler.
Background technology
Coal-fired shell boiler is China's industry and civilian main heat energy supply equipment, fuel is thrown in and carry out the grate firing burning on fire grate, water in the shell is heated, because the diameter of shell is bigger, in case after lack of water went up water immediately, the steam of generation had little time to discharge, after pressure raises, shell holds be can't stand and high pressure be easy to generate boiler explosion accident.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliable, scientific structure is compact, it is fast to boost, efficient is high tubular boiler.
The technical solution of the utility model is: tubular boiler, by body of heater, dry pipe, upper collecting chamber, side collection case, superheater tube, water-cooling wall, the next part case, blow-off pipe, fire grate is formed, two water-cooling walls that the position is relative are set in the body of heater, water-cooling wall is made up of water screen tube, the two ends up and down of water screen tube are communicated with upper collecting chamber and next part case respectively, side collection case is communicated with the water screen tube in the same outside in two water-cooling walls, the two ends of superheater tube are communicated with not two side collection casees in the same side respectively, the lower end of two dry pipes is communicated with upper collecting chamber, stretch out outside the body of heater upper end of dry pipe, steam-water separator is installed in the upper end of one of them dry pipe, safety valve is installed in the upper end of another dry pipe, the upper end of blow-off pipe is communicated with the next part case, and stretch out outside the body of heater lower end of blow-off pipe, and fire grate is installed in the bottom of body of heater.
Preferably, upper and lower layer superheater tube be staggered and arrange, and makes full use of space in the body of heater, superheater tube absorbs that heat is fast, superheater tube is heated evenly, quick heating boosts.
Preferably, dry pipe is provided with the water level meter.
Preferably, horizontal sextant angle α 〉=6 of superheater tube °, unsuitable fouling.
Water is from next part case approaching side collection case, water screen tube, superheater tube, upper collecting chamber, dry pipe, and the steam of generation enters the hot equipment of using through steam-water separator.
The beneficial effects of the utility model are, utilize the little superheater tube of diameter to replace the big shell of diameter, and the withstand voltage height of superheater tube is difficult for blast, and safety coefficient is big, and it is fast to boost, and has improved boiler thermal output.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view in the utility model body of heater.
1 steam-water separator, 2 dry pipes, 3 water level meters, 4 safety valves, 5 upper collecting chambers, 6 bodies of heater
7 side collection casees, 8 superheater tubes, 9 water screen tubes, 10 next part casees, 11 blow-off pipes, 12 fire doors, 13 fire grates.
The specific embodiment
Tubular boiler is made up of body of heater 6, dry pipe 2, upper collecting chamber 5, side collection case 7, superheater tube 8, water-cooling wall, next part case 10, blow-off pipe 11, fire grate 13.Top and position that two water-cooling walls are positioned at body of heater 6 are relative, and water-cooling wall is made up of water screen tube 9.The two ends up and down of water screen tube 9 are communicated with upper collecting chamber 5 and next part case 10 respectively.Side collection case 7 is communicated with the water screen tube 9 in the same outside in two water-cooling walls.The two ends of superheater tube 8 are communicated with not two side collection casees 7 in the same side respectively.Horizontal sextant angle α 〉=6 of superheater tube 8 °.Upper and lower layer superheater tube 8 is staggered and arranges.The lower end of two dry pipes 2 all is communicated with the upper end of 5, one dry pipes 2 of upper collecting chamber and stretches out body of heater 6 outer and connection steam-water separators 1, and body of heater 6 outer and connection safety valves 4 are stretched out in the upper end of another dry pipe 2.The water level meter is set on the dry pipe 2.The upper end of blow-off pipe 11 is communicated with next part case 10, and stretch out outside the body of heater 6 lower end of blow-off pipe 11.Fire grate 13 is installed in the bottom of body of heater 6.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
