Abstract

The utility model relates to a burning furnace for water decomposition, which can decompose the water into the hydrogen and the oxygen for burning. The burning furnace for water decomposition comprises a steam generator, a decomposer, a spraying device, a furnace cellar, etc., and uses the waste heat to decompose the water into the mixture of the hydrogen and the oxygen and then burns the mixture with fuel sufficiently. The utility model has wide range of application, can be used for burning completely in the furnace cellar, such as the boiler, the glass melting furnace, the annealing furnace, the iron-smelting furnace, etc., which use the fuel, such as the coal, the coke, the kerosene, the diesel oil and the heavy oil, etc., and can save energy and protect the environment.

Description

The water decomposition combustion furnace

The utility model relates to a kind of stove and accessory that makes water resolve into hydrogen and oxygen and burning, specifically a kind of water decomposition combustion furnace.

Replace air to spray in the producer with steam, steam and the red-hot coke generation water-gas that works mutually, i.e. the mixture of carbon monoxide and hydrogen, they are flammable gas.In the prior art, a kind of family expenses aquation hydrogen furnace is disclosed in the Chinese patent 94249028.7, it constitutes steam generator by the water tank of annular and the steam pipe of annular, be arranged at the top of shell and flue, and be on the same home position with flue, inboard wall of furnace is coiling the high-temperature spiral separator that is made of the spiral tracheae, link to each other with water pipe through three-way control valve on it, its bottom end is connected to and places on the middle umbrella shape shower nozzle of grate, its weak point is that the coiling helix tube inner vapor flow velocity on the high-temperature spiral separator is too fast, cause the mistake thermal efficiency of steam relatively poor, and the use field is confined to small-sized stove and accessory.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of heat exchanger effectiveness height, saving energy consumption, the wide water decomposition combustion furnace in use field is provided.

To achieve these goals, the utility model provides a kind of new technical solution: this water decomposition combustion furnace comprises parts such as steam raising plant, decomposer, injection apparatus and stove cellar for storing things, comprises steam copper head, appendix, safety valve, Pressure gauge, water inlet pipe, water tank, communicating pipe, water gage and drainpipe at the steam raising plant between chimney bottom and exhanst gas outlet; Decomposer is positioned at the inboard wall of burner hearth place, and it is made of heat conduction shell, decomposer, heat conduction end socket device and control valve, is communicated with appendix through control valve on it, and its underpart end is switched on the uncork shower nozzle through control valve, playpipe; Injection apparatus is made up of uncork shower nozzle, playpipe and control valve, and the stove cellar for storing things is made up of furnace shell, inboard wall of burner hearth and chimney.

Advantage of the present utility model is: the scope of application is extensive, is applicable to coal, coke, kerosene, diesel oil and heavy oil etc. to be stoves such as boiler, glass-melting furnace, annealing furnace, the iron-smelting furnace cellar for storing things of fuel, and sufficient combustion helps energy-conservation and the environmental protection needs.

Accompanying drawing is embodiment of the present utility model.

Fig. 1 is the utility model structural representation.

Below in conjunction with accompanying drawing and concrete embodiment essentiality content of the present utility model is described in further detail.

Among the figure, 1-steam copper head, 2-communicating pipe, 3-loose joint, the 4-water tank, 5-water inlet pipe, 6-safety valve, 7-Pressure gauge, the 8-steam transmitting pipe, the automatic water inlet switch of 9-low level, 10-level pressure device, 11-water gage, the 12-draining valve, 13-heat conduction shell, 14-decomposer, 15-heat conduction end socket, 16-uncork shower nozzle, 17-control valve, 18-playpipe, 19-control valve, the 20-furnace shell, 21-inboard wall of burner hearth, 22-burner hearth burning starting point basal plane, 23-chimney.

Water decomposition combustion furnace shown in the figure, it comprises parts such as steam raising plant, decomposer, injection apparatus and stove cellar for storing things, and the steam raising plant that is positioned between chimney (23) bottom and the exhanst gas outlet comprises steam copper head (1), appendix (8), safety valve (6), Pressure gauge (7), water inlet pipe (5), water tank (4), communicating pipe (2), water gage (11) and drainpipe (12); Decomposer is positioned at inboard wall of burner hearth (21) and locates, it is made of heat conduction shell (13), decomposer (14), heat conduction end socket device (15) and control valve (17), be communicated with appendix (8) through control valve (17) on it, its underpart end is switched on the uncork shower nozzle (16) through control valve (19), playpipe (18); Injection apparatus is made up of uncork shower nozzle (16), playpipe (18) and control valve (19), and the stove cellar for storing things is made up of furnace shell (20), inboard wall of burner hearth (21) and chimney (23).In use, light the fuel of in burner hearth, placing, produce heat simultaneously, the very fast steam that just produces of steam generating device that steam pot head (1) and case (4) constitute, the steam of steam pot head (1) enters on the decomposer that snakelike coil pipe is made with high temperature (14) that is installed in the inboard wall of burner hearth (21) through control valve (17).Decomposer is made by fire-resistant oxidation resistant material, its outside is subjected to the high temperature heating, high heat imports in the steam that flows in the pipe, steam in the pipe at high temperature only needs a spot of heat energy just can overheatedly resolve into the mixed air of hydrogen and oxygen, the resistance of serpentine bend has slowed down the flow velocity of steam and has caused turbulent flow in the pipe, steam in the pipe is absorbed heat more fully and decomposite the mixed gas of hydrogen and oxygen efficiently, mixed air is sprayed burner hearth equably through control valve (19) to uncork shower nozzle (16).Uncork shower nozzle (16) can prevent lime-ash whereabouts plug nozzle, has guaranteed to continue jet in burner hearth.Under the combustion high temperature of carbon monoxide and hydrogen, even if use inferior fuel also can obtain good combustion efficiency.

Through the reality test, have a better effect.
