Abstract
The utility model relates to an atmospheric hot water boiler with an annular boiler hearth. The utility model is composed of fire doors, a fire grate, a boiler hearth, a back smoke passage, a heat transfer box, a chimney, etc. the utility model is characterized in that an annular combustion system is composed of the boiler hearth, the fire grate and the vertical smoke passage; the two fire doors alternately add the coal; the left fire outlet and the right fire outer alternately close; the smoke gas rises in rotation, downwards turns over, and rises again, and then the smoke gas is exhausted. The combustion time of the smoke gas is extended, and the boiler efficiency and the smoke elimination and dust removal effects are improved. The utility model has the advantages of high combustion-off rate, good environmental protection effect, strong bearing ability, wide coal type adaptability, etc.
Description
The utility model relates to a kind of improved vertical normal-pressure hot-water boiler.
Existing vertical circular normal-pressure boiler, a kind of is the double grate counter-burning type, its shortcoming is to require coal tighter, and burning velocity is slow, influences the boiler normal output; Another kind is a normal burning, and its shortcoming is that flue gas flow time in burner hearth is shorter, and fully after-flame not only causes the waste of fuel, and smoke medicining dust-removing effect is relatively poor, contaminated environment.
The purpose of this utility model provides that a kind of adaptation coal is wide, smoke abatement and dust control good, and environmental benefit is comparatively desirable, the better simply normal-pressure hot-water boiler of structure.
The technical solution of the utility model is: burner hearth, fire grate and vertical heating flue are formed the combustion system of a circulus.During boiler work, two fire doors replace coal, when coal when left fire door drops into burner hearth, close the crater in burner hearth left side, the flue gas whole burner hearth of flowing through from left to right in burner hearth enters rear pass from burner hearth right side crater and is rotation status and enters the vertical heating flue after-flame that is arranged in the burner hearth center (when coal dropped into from right fire door, flue gas was rightabout and rotates into vertical heating flue).Along with the part dust of flue gas operation under action of centrifugal force, will drop below vertical heating flue.After taper water jacket below was washed away in rotation flue gas rising front, the garden band of column shape body heat transferring case of flowing through continued to rise, and enters under the boiler tail ring bodies smoke box by smokestack and turns over, and enters atmosphere by chimney at last.
The utility model has the advantages that: adapt to that coal is wide, burn-off rate is high, environmental benefit good, cost is low, easy to operate, bearing capacity strong, suitable row safety.
Important technological parameters is
Thermal power: 0.35MW
Grate area: 1.3M
2
Combustion space: 1.17M
3
Leaving water temperature: 95 ℃
Return water temperature: 70 ℃
Exhaust gas temperature: 200 ℃
The thermal efficiency (η): 74%
Pressure: normal pressure
Adapt to coal: bituminous coal, anthracite, meager coal
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the utility model chamber structure cutaway view.
Embodiment of the present utility model is an example with the stove of 0.35MW (300,000 kilocalories/time): burner hearth (6), fire grate (7) and vertical heating flue (8) are formed the combustion system of a circulus, two fire doors are used alternatingly, when coal drops in the burner hearth by left fire door (9), close left side crater (10), the flue gas burner hearth (6) of flowing through from left to right, by right side crater (11) enter rear pass (12) be the rotation shape enter vertical heating flue (8), washing away taper water jacket (5) rises, dispel the heat by heat transfer case (4), enter under the smoke box (3) through smokestack (2) again and turn over, enter atmosphere by chimney (1) at last.Flue gas flow is eddy flow and rises and to turn over down more in sum, after the combustion again rising wash away stove heat-transfer area each several part, enter atmosphere from chimney at last.Burner hearth (6) is outer highly to be 1000mm through being 1800mm, makes of the steel plate of 4.5mm, fire grate (7) is a gray iron casting, vertical heating flue (8) internal diameter is 400mm, and water interlayer 80mm makes with the steel plate that 6mm is thick, the boiler body external diameter is 1400mm, make of the steel plate that 4mm is thick, the angle of rear pass (12) is 90 °, heat transfer case (4) height 1800mm, make of the steel plate that 6mm is thick, the body of heater total height is 2800mm.
Claims (4)
1, a kind of ring-type burner hearth normal-pressure hot-water boiler of being made up of fire door, fire grate, burner hearth, flue, heat transfer case, chimney etc. is characterized in that burner hearth (6), fire grate (7) and vertical heating flue (8) composition one ring-type burning after-flame system.
2,, it is characterized in that burner hearth (6) is that most ring-types are to ring bodies according to the said ring-type burner hearth of claim 1 normal-pressure hot-water boiler.
3,, it is characterized in that fire grate (7) is filled to ring bodies for encircling mostly according to the said ring-type burner hearth of claim 1 normal-pressure hot-water boiler.
4,, it is characterized in that the center of burner hearth (6) is provided with a vertical heating flue (8) according to the said ring-type burner hearth of claim 1 atmospheric hot-water boiler.
