Abstract
The utility model discloses a positive and negative combustion integrated coal boiler, which is provided with two combustion chambers, a positive and a negative combustion air inlets, and a secondary wind air inlet. Water flows from a warm water tank to a boiled water tank in the boiler, which fully enhances heat efficiency; in addition, a coal preparing tank and an automatic water supplying device are provided. The utility model is suitable to all hand-fired boilers.
Description
The utility model relates to boiler manufacturing technology field, specifically a kind of positive and negative burning one coal-burning boiler.
At present, hand coal-fired boiler on the market, having many is because give the wind condition bad, can not make the CO of the reducing zone generation in the combustion chamber and the volatile matter after-flame that pyrolytic layer is separated out, thereby having influenced the thermal efficiency of boiler and the quality of discharging fume, the water temperature in most of boilers all is along with water integral elevating in the boiler.Like this, property heating cycle that is bound to is long, and power consumption is high; In addition, handwarmer stoker workman adds water, and the coal number of times is more, and labour intensity is bigger.
The purpose of this utility model is to want to provide a kind of can improve the thermal efficiency, improves the smoke evacuation quality, realizes adding automatically water, reduces the coal number of times, makes water circulation automatically in boiler, realizes warm water, and boiling water is supplied simultaneously.
The technical solution of the utility model is as follows:
The utility model has two combustion chambers, above first combustion chamber, there is one to be equipped with coal bin, under first combustion chamber furnace grate ventilation is arranged, realize forward combustion, the coal filling hole that is equipped with coal bin has covered air door, can realize reverse burning, the clean-out door of first combustion chamber can be for secondary wind, be located between the first combustion chamber oxide layer and the reducing zone by the flame hole of first combustion chamber to the second combustion chamber transition, help the CO of reducing zone generation and the volatile matter that pyrolytic layer is separated out, by red-hot oxide layer, again through the very high flame hole of excess temperature to the second combustion chamber after-flame, just cancel air door (6) that coal covers and the air door (7) on the clean-out door if adopt flat upright tower fire grate, finish the function of positive and negative burning one and secondary wind by flat upright tower fire grate, flue gas is after second combustion chamber is washed away by the water pipe with horizontal stagger arrangement, again through arranging heavenwards by chimney behind the convection pass at top reservoir place.
The Automatic Water System that is contained in upper boiler is to be connected with lever by a ball float, and when water level descended, ball float descended thereupon, and the lever drives tapered piston rises, and makes ring-shaped water jacket can give boiler feed water, otherwise, then stop into water.
Be divided into reservoir and boiled water tank in the boiler, water is recurrent state and flows in boiler, can fully improve the thermal efficiency, also can supply warm water and boiling water simultaneously.
The utility model has the advantages that: changed boiler emission flue gas quality, be beneficial to environmental protection, improved boiler thermal output, realization water-feeding automation and warm water, boiling water are supplied simultaneously, have reduced the coal number of times, therefore, have alleviated stoker's working strength of workers.

Embodiment 1:
Shown in Figure 6 as Fig. 1 Fig. 5, coal bin (1) is straight-through up and down fully to have one in the top of first combustion chamber (2), on the coal flap (5) of coal bin (1) air door (6) is arranged fully, it can be plain grate and semicircle fire grate that the fire grate of air door (7) first combustion chamber (2) lower curtates on air door (3) and the clean-out door is arranged under first combustion chamber (2), it also can be flat upright tower fire grate, just cancel air door (6) that coal filling hole covers and the air door (7) on the clean-out door if adopt flat upright tower fire grate, finish the function of the integrated and secondary wind of positive and negative burning by flat upright tower fire grate, flat upright tower fire grate is made up of four parts from bottom to top, being that plain grate (27) truncated cone fire grate (28) cylinder fire grate (26) and this four part of cone cap (29) can be combined types, also can be one.The bottom of cylinder fire grate (26) and conical cap (29) are outwards stuffy, between first combustion chamber (2) and second combustion chamber (9), flame hole (8) is arranged, the water pipe (10) that horizontal stagger arrangement is arranged in second combustion chamber (9), the door (14) that a cleaning laying dust ash is arranged at second combustion chamber (9) sidewall, there is convection pass (11) top of boiler, in convection pass (11), the water pipe (30) that horizontal stagger arrangement is arranged, a pressure port (13) is arranged on chimney (12), when the needs banking fire, open pressure port (13), reduce the suction of chimney burner hearth.
An Automatic Water System (15) is arranged above boiler one side, as shown in Figure 6, it has a tap water interface (21) and a ring-shaped water jacket that communicates with it (22), in ring-shaped water jacket (22), a tapered piston (24) is arranged, between tapered piston (24) and the ball float (23) lever is arranged, when water level descended, ball float (23) descended thereupon, lever is mentioned tapered piston (24), at this moment, the water in the ring-shaped water jacket (22) flows out by following delivery port (25), otherwise, ball float (23) floats, tapered piston (24) falls, and seals ring-shaped water jacket (22), and delivery port (25) stops water outlet.
As can be seen from Figure 5, connect water-adding bucket (16) below the Automatic Water System (15), water-adding bucket (16) communicates with filler pipe (17), filler pipe (17) communicates with reservoir (18) bottom, reservoir (18) top communicates with filling pipe (19) top, and filling pipe (19) bottom communicates with boiled water tank (20) bottom, therefore, no matter be that reservoir (18) water level descends or boiled water tank (20) water level descends, all can cause Automatic Water System (15) automatic water supplement.Embodiment 2:
As can be seen from Figure 2, embodiment (2) is a box furnace with the difference of embodiment (1).
