Abstract

The utility model relates to a household kitchen stove, particularly a hydration hydrogen stove which uses water to support the combustion. The water passing through a steam generator which is arranged on a hearth and a housing is changed into steam, and after passing through a high temperature spiral separator which is arranged on the inner wall of the hearth, the steam is formed into overheating hydrogen and oxygen, and the overheating hydrogen and oxygen are sprayed into the hearth through an umbrella-shaped spray head to be combusted. The utility model has the advantages of high combustion speed, high efficiency and energy saving effect.

Description

The aquation hydrogen furnace

The utility model relates to a kind of family kitchen stove and accessory, and is particularly a kind of with the combustion-supporting aquation hydrogen furnace of water.

Chinese patent specification CN2033089U discloses the combustion-supporting coal fire cooking stove of a kind of service water, it is the hearth outer wall coiling water pipe at common coal fire cooking stove, on the pipe with spiral pipe, following two ends are respectively into, delivery port, and by-pass valve control is housed respectively, on pipe with spiral pipe, weld the water spray arm of drawing a band control valve and stretch into burner hearth, nozzle is equipped with in the termination, when water is heated in the pipe with spiral pipe, produce certain pressure, open the control valve of water spray arm, water vapour can spray on the burner hearth fire combustion-supporting, its weak point is that nozzle is in top, the burner hearth top steam of spraying water in burner hearth, can be combustion-supporting when flame is high, when using conventional fuel flame low, then do not have combustion-supporting effect, can only use high-grade fuel, purposes is narrow; Helix tube places hearth outer wall, and the water that is flowed in the pipe absorbs the burner hearth heat in a large number, influences fire box temperature, and herein, what nozzle sprayed is water vapour, and combustion-supporting effect is poor, so that ignition temperature is low, and ignition speed is slow, and temperature just is difficult to control.

Task of the present utility model provides the energy-conservation aquation hydrogen furnace that a kind of suitable family uses, and it can make various solid fuels carry out quick low temperature ignition burning easily.

For solving above-mentioned task, technical solution of the present invention is: will be placed the top of shell and flue by the steam generator that steam-generating tube and water tank constitute, be provided with steam-water channel between water tank and the steam-generating tube, a board-like adjustment switch that can move up and down and adjust is set in the space between shell and flue, offer passage on the flue courage wall, and on inboard wall of furnace, coiling the high-temperature spiral separator that constitutes by the spiral tracheae, link to each other with water tank by three-way control valve on it, its bottom end is connected to and places on the middle umbrella shower nozzle of grate.

In order to reach better effect, this aquation hydrogen furnace adopts the steam generator of ring-type, and the diameter of steam-generating tube is less than the diameter of flue, and is on the same home position with flue.

Owing to adopted high-temperature spiral separator and board-like adjustment switch in the above-mentioned technical solution, on flue, offered passage, and the umbrella shower nozzle placed in the middle of the grate, can use various solid fuels, of many uses, the fire box temperature height, what the umbrella shower nozzle sprayed is overheated hydrogen, oxygen gas mixture, ignition speed is fast, and combustion-supporting effect is good.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model aquation hydrogen furnace.

Among the figure, 1-water inlet, 2-three-way control valve, 3-steam generator, 4-delivery port, 5-flue, 6-board-like adjustment switch, 7-shell, 8-high-temperature spiral separator, 9-umbrella shower nozzle, 10-grate, 11-air intake ash hole, 12-water tank, 13-steam-generating tube, 14-passage, 15-steam-water channel

Aquation hydrogen furnace shown in the figure comprises shell (7), flue (5), steam generator (3), grate (10), umbrella shower nozzle (9), air intake ash hole (11), high-temperature spiral separator (8) and board-like adjustment switch (6).Flue (5) places in the shell (7), constitute cylindrical space between flue (5) and the shell (7), board-like adjustment switch (6) places in this space, can move up and down and adjust, be same as the bottom that the grate (10) of putting fuel is positioned at flue (5), grate (10) is logical air intake ash hole (11) down, steam generator (3) is made of the water tank (12) of annular and the steam generator tube (13) of annular, which is provided with water inlet (1) and delivery port (4), and by-pass valve control is housed respectively, be arranged with four steam-water channels of making by the high-temperature steel pipe (15) between water tank (12) and the steam-generating tube (13), the diameter of steam-generating tube (13) is less than the diameter of flue (5), and is on the same home position with flue (5).Have passage (14) on flue (5) the courage wall, high-temperature spiral separator (8) is the fire-resistant oxidation resistant spiral tracheae that coils in flue (5) inwall, be connected with water tank (12) through three-way control valve (2) on it, its bottom end is connected to and places on the middle umbrella shower nozzle (9) of grate (10).Water vapour and red-hot coke interact and can generate the water-gas of being made up of hydrogen and CO gas, hydrogen and CO gas are the fuel gas that can produce high heat, the utility model aquation hydrogen furnace is with main fuel water with the matrix bunker coal, solid fuel cofirings such as bavin form water-gas generation high temperature high heat, its theory of combustion is as follows: flue (5), passage (14), board-like adjustment switch (6), form the passage of paying of flame and heat between shell (7) and the interior break joint of steam generator (3), this pair passage is after board-like adjustment switch (6) moves down, the heating surface area of steam generator (3) is with water tank (12), the whole steam generator (3) that steam-generating tube (13) and steam-water channel (15) are formed, promptly form the quick angry device of a big heating surface area, after water being injected water inlet (1), move down board-like adjustment switch (6), in flue (5), place coal, bavin, solid fuels such as chaff shell, point burner internal combustion material, the water tank (12) in the steam generator (3) then, steam-generating tube (13) and steam-water channel (15) thereof all are in heating status, can produce water vapour at short notice rapidly, open and adjust three-way control valve (2), the water vapour that produces in the steam generator (3) enters in the high-temperature spiral separator (8) of fire-resistant oxidation resistant through three-way control valve (2), and high-temperature spiral separator (8) is the spiral tracheae that coils in flue (5) inwall, its outside is subjected to the high temperature heating, heat imports in the steam that flows in the pipe, water vapour in the pipe at high temperature only needs little heat to get final product overheated hydrogen and the oxygen isolated, overheated hydrogen and oxygen are evenly sprayed in the burner hearth through the umbrella shower nozzle, umbrella shower nozzle (9) both can guarantee to continue jet in burner hearth, can prevent that again ashes from falling so that plug nozzle.Oxygen generates carbon monoxide with the carbon reaction, the water-gas combustion flame is yellow orange white, under the effect of water-gas, even use colm or bavin also ignition fast when being in the low state of temperature in the burner hearth, after flame is normal can on move board-like adjustment switch (6) to the top, this moment, fire box temperature enough highly only needed steam-generating tube (13) in the steam generator (3) partly to be heated can to produce enough steam.

Our experiments show that test and use result are good:

Jet when burning common bavin, the white high 35cm of flame orange, 1kg water 2 minutes is boiled, burns 30 minutes need bavin 0.6kg; Jet when burning 2 normal cellular coals, the high 20～30cm of flame orange white, boiled 1kg water needs 3.2 minutes, connects to bank up a fire at interior 3～4 in the honeycomb briquette that day and night needs; Burnt 2 honeycomb briquettes jet 5 hours continuously, flame height direct proportion all the time is higher than 3 times of conventional oven flame.
