Abstract

The utility model discloses a coal combustion furnace with a carbonization chamber, comprising a coal feeding opening, a furnace chamber, a furnace grate, an air inlet, etc. The utility model is characterized in that the furnace is provided with an anti-combustion carbonization chamber of inverse burning whose upper end is provided with the coal feeding opening and the lower end forms a fire opening with the inner wall of the furnace chamber. The utility model has the advantages of excellently satisfying the condition of displaying the perfect combustion and eliminating the phenomenon of black smoke generation in the combustion and improving the heat efficiency. The coal quantity is saved by 1/3, low cost, low investment, easy operation and the environment protecting requirements are obtained. The utility model is suitable to being used for the civil coal combustion furnace, the industrial boiler, the kiln furnace and the boiler generating black smoke and can combust the oil residue, the oil sludge, the briquette and the mixture of the domestic garbage and the coal without black smoke generation and the garbage is effectively processed.

Description

Destructive distillation storehouse coal furnace

Technical field

The utility model belongs to a kind of coal furnace, particularly a kind of destructive distillation storehouse coal furnace.

Background technology

Coal-fired have two parts heating in combustion process, i.e. fugitive constituent and fixed carbon, fixed carbon wherein are over-emitting black exhaust not in combustion process, and the coal furnace over-emitting black exhaust is because fugitive constituent does not reach due to the completing combustion.Present coal furnace structure can't finely satisfy the condition of fugitive constituent completing combustion, thereby has the phenomenon of over-emitting black exhaust.

The utility model content

The purpose of this utility model provides a kind of destructive distillation storehouse coal furnace, the fine condition that satisfies fugitive constituent completing combustion of energy, the phenomenon of elimination burning over-emitting black exhaust.

The purpose of this utility model is achieved by the following technical solution: it comprises coal feeding hole, burner hearth, grate and air inlet etc., it is characterized in that: stove is provided with the anti-destructive distillation storehouse of burning of backfire, the upper end in destructive distillation storehouse is provided with coal feeding hole, forms burner between the lower end in destructive distillation storehouse and the inwall of burner hearth.

The utility model has the advantages that: 1, the fine condition that satisfies fugitive constituent completing combustion of energy, the phenomenon of elimination burning over-emitting black exhaust economizes on coal 1/3, reaches environmental requirement.2, not slagging scorification of fire coal, combustion conditions is good.3, do not advance cold wind, good heat insulation improves the thermal efficiency, and 4, low, the small investment, easy to operate of cost, improve operating environment.5, be applicable to civil stove and accessory, Industrial Boiler, kiln and existing over-emitting black exhaust boiler.6, the not over-emitting black exhaust of the dregs of fat, greasy filth, moulded coal and house refuse and coal for mixing combustion that is suitable for burning, effectively disposal of refuse.

Fig. 2 is the utility model embodiment two structural representations.

The specific embodiment

Embodiment one structure: see Fig. 1, destructive distillation storehouse 3 is set on stove, the upper end in destructive distillation storehouse 3 is provided with coal feeding hole 1, forms burner 8 between the side inwall 9 of the lower end in destructive distillation storehouse 3 and burner hearth 5.In the bottom of burner hearth 5 grate 6 is set, the bottom of body of heater is provided with air inlet 7.

Operation principle: because destructive distillation storehouse 3 is set, thereby realizes that backfire is counter and burn that promptly fire is preceding, cigarette after, first destructive distillation, after-combustion; Last burning cigarette, make charcoal down (be that destructive distillation storehouse 3 solves cigarette, destructive distillation storehouse lower hearth 5 solves the charcoal fire burning, occurs angle of repose 10 between burner hearth 5 and crater 8, forms the two-part burning).Coal feeding hole 1 in destructive distillation storehouse 3 is knocked down fire coal, coal-fired after retort section 2 destructive distillation, coal gas (flue gas) is under suction function, go from top to bottom from the air that coal feeding hole 1 enters, passing through red-hot charcoal fire section 4 decomposes, change into coal gas CH4, H2, CO or the like, reach completing combustion (tar, CmHn decompose), the charcoal fire charcoal fire section 4 in burner hearth from top to bottom fully burns.

Embodiment two structures: see Fig. 2, the both sides inwall 9 of the lower end in destructive distillation storehouse 3 and burner hearth 5 or form burner 8 all around between the inwall 9.Other is with embodiment one structure.

Claims

1, a kind of destructive distillation storehouse coal furnace, it comprises coal feeding hole, burner hearth, grate and air inlet etc., it is characterized in that: stove is provided with the anti-destructive distillation storehouse of burning of backfire, and the upper end in destructive distillation storehouse is provided with coal feeding hole, forms burner between the lower end in destructive distillation storehouse and the inwall of burner hearth.
