Abstract
The utility model relates to a three-way burning boiler, which comprises a boiler body of which the front end is provided with an air-distribution plate of which the front end is provided with an air door. The lower part of the boiler body is provided with a grate, the middle lower part of the boiler body is provided with a burner port, and the rear end of the boiler body is provided with an ash removal door; the upper end of a coal bunker in the boiler body is provided with a coal bunker cover, and the upper part is provided with a spray pipe. The utility model has high burning speed and convenient ash removal, and the smoke dust discharge amount can reach less than 90 mg/nm<3>, and the burning efficiency can be enhanced.
Description
Technical field: the utility model relates to a kind of boiler, especially a kind of boiler of three-dimensional burning of burn raw coal or moulded coal.
Background technology: at present, the not fully burning of fugitive constituent of separating out during in destructive distillation at the coal of handwarmer internal combustion is not because have higher temperature and sufficient oxygen, so to the airborne release black smoke, cause environmental pollution.Though and simple and easy in the past gas burner can be eliminated the phenomenon of over-emitting black exhaust preferably, but all be the coal at intermittence, once add dress, boiler is moved continuously, influence result of use, though and comparatively advanced at present bilateral-firing boiler has solved the problems referred to above, also there are problems such as burning velocity is slow, the difficult removing of convection heating surface dust stratification.
Summary of the invention: provide a kind of three-dimensional burning boiler for the problems referred to above that solve the bilateral-firing boiler, it can not only keep the advantage of bilateral-firing boiler, and has solved the problem that bilateral-firing boiler combustion speed is slow, the convection heating surface dust stratification is removed than difficulty.
Concrete technical scheme is as follows: a kind of three-dimensional burning boiler, comprise body of heater, front end at body of heater is provided with air distribution plate, the air distribution plate front end is provided with air door, be provided with fire bars in the body of heater bottom, be provided with port, be provided with shoot door in the rear end of body of heater in the body of heater middle and lower part, coal bunker upper end in body of heater is provided with the coal bunker lid, and top is provided with spray pipe.
The degree of depth of coal bunker is 600-1600cm.
Bottom at body of heater is provided with explosion proof door.
The end face of port tilts, and its inclination angle is between 30-60 °.
Compare with prior art, the utility model adopts said structure, and the degree of depth of coal bunker can make the coal seam thickening between 600-1600cm, ash bed, oxide layer, destructive distillation layer, drying and preheating layer (from bottom to top) are arranged in body of heater like this.Be provided with port in the middle and lower part of body of heater (between oxide layer and the reducing zone).During boiler operatiopn, portion of air arrives oxide layer coal supply burning (direction one) from the bottom of fire bars 5 by ash bed; Another part air arrives oxide layer overheavy firing (direction two) from air door 4 through air distribution plate 3; The fugitive constituent that coal goes out at the destructive distillation chromatography contacts with red-hot oxide layer by reducing zone and by completing combustion (direction three), thereby eliminates flue dust.Be arranged on the coal trickle that the spray pipe on coal bunker top can be in coal bunker, make the coal humidity, can reach by control trickle amount and help producing coal gas effect or banking fire; Air door 4 can be regulated intake, makes the state that boiler can be desirable transfer wind; Shoot door 7 can be removed the dust stratification on the heating surface, makes boiler exhaust gas unobstructed, improves the heat exchange effect; The utility model burning velocity is fast, and deashing is convenient, and smoke discharge amount can reach≤90mg/NM
3, and improved efficiency of combustion.
Description of drawings: the utility model is elaborated below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of three-dimensional burning boiler, comprise body of heater 9, front end at body of heater 9 is provided with air distribution plate 3, air distribution plate 3 front ends are provided with air door 4, can regulate intake, the fire bars 5 that to be provided with a plurality of rotating sections in body of heater 9 bottoms be rhombus, be provided with port 6 in body of heater 9 middle and lower parts, the end face of port 6 tilts, and its inclination angle is between 30-60 °, be provided with openable shoot door 7 in the rear end of body of heater 9, coal bunker upper end in body of heater 9 is provided with coal bunker lid 1, and coal bunker top is provided with spray pipe 2, and the degree of depth of coal bunker is between 600-1600cm; Be provided with explosion proof door 8 in the bottom of body of heater 9, can prevent detonation, guarantee safe operation of the boiler.
