Abstract

The utility model provides a coal secondary combustion furnace, which carries out reconstruction on the basis of an original cooking range, wherein the problem that fuel can not be combusted fully can be effectively solved, the coal secondary combustion furnace comprises a jamb, a slag storage chamber, an ash outlet and a water tank, wherein a furnace grate and a flame-proof furnace core are combined into a combustion chamber, a secondary air inlet hole is dug between the furnace core and an inner heated furnace body, the slag storage chamber is arranged under the furnace grate, an air inlet hole is arranged besides the slag storage chamber, the air inlet hole is connected with a fan, exhaust gas generated after coal is burnt fully is discharged from the furnace through a flue composed of flue heating flanges, the flue heating flanges and an external furnace body are combined into a water storage chamber, a water inlet is arranged on upper portion of the furnace body, a water outlet pipe is arranged on the front lower portion, the problem that furnaces must be provided with chimneys is solved, the combustion furnace can save coal for 50% after reconstruction, the heat efficiency can be improved by 50%, thereby achieving the purposes of saving energy and protecting environment, and the combustion furnace has the advantages that the investment is small, and the furnace takes effect rapidly.

Description

Coal after-burning stove

Technical field

The utility model relate to a kind ofly cook a meal, the radiator tool, a kind of specifically coal after-burning stove.

Background technology

In the daily life, because the unilateral pursuit of most of boiler increases endotherm area, think that the big more heat that can improve more of endotherm area transforms, but we find the big cauldron that uses to industrial and mining enterprises, little to family cook the dense black smoke that stove and accessory emitted that uses mostly since coal burning not exclusively cause, because burning is incomplete, has not only caused the pollution of surrounding environment, and has caused a large amount of wastes of the energy.

Summary of the invention

The utility model provides a kind of coal after-burning stove, transforms on the basis of original stove and accessory, and can effectively solve fuel can not clean-burning problem, and saves a large amount of energy.

The utility model is achieved in that this coal after-burning stove is made up of burner, dreg chamber, ash hole, water tank, wherein, fire bars and refractory stove core are formed the combustion chamber, combustion chamber and in the excavation secondary air inlet hole that is heated between the body of heater, it below the fire bars dreg chamber, dreg chamber leaves air admission hole in the next door, air admission hole connects blower fan, waste gas after coal burning is complete discharges out of the furnace from the flue of being made up of the flue heating plate, flue heating plate and external furnace body are formed reservoir chamber, upper of furnace body has water inlet, and outlet pipe is arranged at preceding bottom.

The beneficial effects of the utility model are: having removed has stove with regard to the problem of chimney is arranged, and can save 50% coal through improved combustion furnace, improves the thermal efficiency 50%, thereby reaches the purpose of energy-saving and environmental protection, and has the advantage of small investment instant effect.

Description of drawings

Be described further below in conjunction with accompanying drawing

Fig. 1 is a structural representation of the present utility model

Fig. 2 is a top plan view of the present utility model

Among the figure 1, outlet flue 2, water inlet 3, flue heating plate 4, in be heated body of heater 5, secondary air inlet hole 6, refractory stove core 7, fire bars 8, blower fan 9, dreg chamber 10, ash hole 11, outlet pipe 12, reservoir chamber 13, flue 14, external furnace body

The specific embodiment

As shown in the figure, coal is in the combustion chamber internal combustion of fire bars 7 and refractory stove core 6 compositions, slag falls into dreg chamber 9, blower fan 8 is sent into dreg chamber 9 to air, it is combustion-supporting that air enters the combustion chamber, coal is heated and is gasified in the combustion chamber, produce a large amount of methane, carbon monoxide, fuel gas such as hydrogen, the air that is entered by secondary air inlet hole 5 can help these fuel gas completing combustion, it is comparatively abundant to burn, and burns completely that waste gas enters flue 13, and waste heat heats the water in the reservoir chamber 12 by flue heating plate 3, last waste gas is discharged from outlet flue 1, and flue 13 residual a small amount of lime-ash are discharged by ash hole 10.

Outlet pipe 10 provides hot water, and is drinkable or enter heating passage heating.

Claims

1, a kind of coal after-burning stove, be made up of burner, dreg chamber, ash hole, water tank, it is characterized in that, fire bars and refractory stove core are formed the combustion chamber, combustion chamber and in the excavation secondary air inlet hole that is heated between the body of heater, be dreg chamber below the fire bars, dreg chamber leaves air admission hole in the next door, and air admission hole connects blower fan, waste gas after coal burning is complete discharges out of the furnace from the flue of being made up of the flue heating plate, flue heating plate and external furnace body are formed reservoir chamber, and upper of furnace body has water inlet, and outlet pipe is arranged at preceding bottom.
