Abstract

The utility model relates to a hearth in cooking stoves, comprising an ordinary hearth, a fire grate, an ash area, a fore chamber, a stove cover and a flue. The utility model is characterized in that a smoke eliminator is arranged on the lower end of the ordinary hearth and above the fire grate, the smoke eliminator comprises a wind gathering hood, ventilating poles and a supporting ring, the ventilating poles are uniformly dispersed on the supporting ring, and the wind gathering hood is covered on the supporting ring. A cooking stove made adopting the utility model expels no dense smoke at the time of burning bituminous coal and has the advantages of energy caving, environmental protection and wide applicable range. Except for being used by household cooking stoves, the utility model is also suitable for middle type of water heating boilers, small type of water heating boilers, metal melting stoves, industrial kilns used for producing ceramics, etc.

Description

Smokeless burner hearth

The utility model relates to the burner hearth in the stove and accessory, particularly a kind of smokeless burner hearth.

The mode of traditional coal combustion is to add stove under the common burner hearth to calculate, and the volatile matter during this combustion system bituminous coal in the bituminous coal can not fully burn, and dense smoke discharges from flue, has wasted the energy and has polluted environment again.

The purpose of this utility model provides a kind of volatile matter in the bituminous coal can being burnouted at the burner hearth internal combustion, and flue does not have the smokeless burner hearth that dense smoke is discharged again.This burner hearth is energy savings both, protects environment again.

The concrete technical scheme that realizes the utility model purpose is: smokeless burner hearth comprises common burner hearth, fire grate, clinker area, fire box bell and flue, characteristics be at common burner hearth lower end, fire grate above be provided with a smoke eliminator; This smoke eliminator comprise wind gathering cover, ventilation post (ring), support ring (post J, ventilation post (ring) is evenly distributed on the support ring (post), the wind gathering cover cover is thereon; Smoke eliminator is circular cone shape.

The utility model energy savings, the protection environment, applied widely, except that being used for family, also being applicable to middle-size and small-size hot-water boiler, metal molten stove and producing the Industrial Stoves etc. of ceramic usefulness.

The embodiment that provides below in conjunction with accompanying drawing is described in detail the utility model:

With reference to Fig. 1, bituminous coal falls into after burning in the smoke eliminator 2 from burner hearth 1 suitable for reading adding, at this moment, burn just prosperous coal or do not have the ashes of cooling to heat air in the smoke eliminator 2, smoke eliminator 2 will exhaust be air blast in burner hearth, rouse into air themperature this moment more than several Baidu Celsius, high temperature air mixes fully burning of back with flue gas, the flame that produces is Lan Se or white, and slag falls into clinker area 3 at last, and deashing adopts fire grate 4, flame rises to fire box 5, and flue gas is discharged from flue 6.

With reference to Fig. 2, it is the structural representation of domestic water radiator, has increased a water jacket 10 in the outside of common burner hearth 1.Combustion process is at common burner hearth 1, smoke eliminator 2, finish in the clinker area 3, water jacket 10 inwalls are the 10 inwall heat supplies of 1 pair of water jacket of common burner hearth, flame is to water jacket 10 outer wall heat supplies, hot water is confessed from hot water outlet 11, and cold water replenishes from cooling water inlet 12, the temperature that vent 13 is regulated roasted room 14, flue gas is discharged from flue 6, but roasted room 14 baked foods.

With reference to Fig. 5, it is the structural representation of metal molten stove.Combustion process is finished in common burner hearth 1, smoke eliminator 2, clinker area 3, two heat supply burners 17 have been provided among the figure, can design several according to instructions for use in the enforcement, temperature in the fire box 5 can reach more than thousand degree Celsius, crucible 15 is used for the deposite metal, bell 18 is used for accelerating the speed that crucible heats up, and insulation cover 16 is used for improving the temperature of fire box 5, and flue gas is discharged from flue 6.

With reference to Fig. 6, it is the structural representation of firing ceramics stove.Combustion process is finished in common burner hearth 1, smoke eliminator 2, clinker area 3, and firing ceramics in the kiln body 19 also can be fired refractory material and other products, and flue gas is discharged from flue 6.

With reference to Fig. 7, it is the structural representation of medium and small hot-water boiler.Combustion process is finished in common burner hearth 1, smoke eliminator 2, clinker area 3, pot body 20 is in the high-temperature region, this district sets up and is subjected to hot-water line 21, increased heat exchange area like this, hot water is confessed from hot water outlet 11, this time after the heat exchange, flue gas still has higher temperature, flue gas is reduction of speed in flue gas reduction of speed district 22, increased heat exchanger time, low temperature pot body 23 plays energy recovery effect, and cold water enters from cooling water inlet 12, water through 23 heating of low temperature pot body is supplied with high temperature pot body 20 through connecting water pipe 24, and flue gas is discharged from flue 6.

Claims (3)

1, a kind of smokeless burner hearth, it comprises common burner hearth (1), fire grate (4), clinker area (3), fire box (5), bell (18) and flue (6), it is characterized in that lower end, fire grate (4) top in common burner hearth (1) is provided with a smoke eliminator (2):

2, smokeless burner hearth according to claim 1, it is characterized in that smoke eliminator (2) comprises wind gathering cover (7), ventilation post (ring) (8), support ring (post) (9), ventilation post (ring) (8) is evenly distributed on the support ring (post) (9), and wind gathering cover (7) covers thereon;
