The other part of the stove body is provided with the water pipe which is communicated with the mixing burning chamber, and the lower part of the stove body is provided with a blower opening and a wind blocking plate. The upper side of the mixing burning chamber is opened with an opening for cooking, and the lower side is provided with a flame height adjusting plate. The structure of the wind or the generation of the wind can be achieved through the forced ventilation of the blowing or the wind guiding. The outside of the stove body is provided with a wind adjusting door and a wind blocking door of a main air duct. The utility model not only solves the problem of the insufficient burning of the boiler and the black smoke and can achieve the multiple use, with the average saved energy being more than 40 percent. The utility model is simple in structure, convenient in use and can regain the cost of the boiler in a very short period of time.

Description

Reverse combustion type is used coal-burning boiler more

Technical field

The utility model has related to a kind of boiler, has particularly related to a kind of reverse combustion type and has used coal-burning boiler more.

Background technology

Boiler is an important heat supply equipment in the national economy, industries such as electric power, machinery, metallurgy, chemical industry, weaving, papermaking, food, and industry and civil heating all need a large amount of heat energy of boiler supply.Small-sized multipurpose boiler commonly used at present is generally direct-fired, because fuel burning when burning is insufficient, generates with a large amount of black smokes, not only wastes fuel, also contaminated environment; Though back firing boiler can solve the over-emitting black exhaust problem, owing to be subjected to the restriction of self structure, can not realize heats up water cooks and waits other purposes.

Summary of the invention

The utility model has overcome shortcoming of the prior art, has proposed a kind of reverse combustion type and has used coal-burning boiler more, has not only solved the problem of over-emitting black exhaust, and can be used for heating up water cooking.

For addressing the above problem, the utility model by the following technical solutions:

A kind of reverse combustion type is used coal-burning boiler more, its structure comprises firing door, coal store, fire grate, hybrid combustor, water pipe, be provided with the water leg dividing plate in the body of heater, body of heater is divided into three parts, the body of heater upper end is provided with firing door and last dust-cleaning door, the firing door bottom connects coal store, be provided with fire grate in the coal store, coal store is provided with clean-out door outward, coal store communicates with the hybrid combustor of body of heater mid portion, in another part space of body of heater water pipe is housed, communicates with hybrid combustor, the body of heater lower end is provided with blower fan mouth and deep bead.

The top of hybrid combustor has the kitchener mouth, and the below is provided with flame height and adjusts plate, can adopt the force ventilated structure of air blast or air inducing also can natural air distribution, and body of heater is provided with main air duct air register and wind blocking door outward.

The beneficial effects of the utility model are:

1, body of heater adopts novel structure, the no black smoke that burns, and energy-conserving and environment-protective have reduced pollution, have protected environment.

2, under the situation of normal heating, can also heat up water and cook, multi-use, it is convenient promptly to save again.

3, can select forced burning and spontaneous firing dual mode for use, improve the utilization rate of boiler oil significantly, widen the scope of using coal, under the situation of equal heat supply, reduce coal-fired cost 40%, meet conservation-minded society and environment-friendly type social requirement.

Description of drawings

Fig. 2 uses the coal-burning boiler vertical view for reverse combustion type more

Fig. 3 uses the coal-burning boiler left view for reverse combustion type more

Among the figure: 1, firing door 2, kitchener mouth 3, last dust-cleaning door 4, outlet flue 5, coal store 6, last air inlet 7, main air duct 8, clean-out door 9, ashpit 10, blower fan mouth 11, water leg dividing plate 12, flame height are adjusted plate 13, hybrid combustor 14, water pipe 15, main air duct air register 16, wind blocking door 17, deep bead 18, fire grate 19, water-cooling wall

The specific embodiment

A kind of reverse combustion type is used coal-burning boiler more, its structure comprises firing door 1, coal store 5, fire grate 18, hybrid combustor 13, water pipe 14 etc., be provided with water leg dividing plate 11 in the body of heater, body of heater is divided into three parts, water leg dividing plate 11 has the flue gas communication port, force flue gas to change the nature circulation status, flue gas has effectively prolonged flue gas and has circulated heat time heating time in the S-type horizontal movement of boiler internal; The body of heater upper end is provided with firing door 1 and last dust-cleaning door 3, firing door 1 bottom connects coal store 5, be provided with fire grate 18 in the coal store 5, the coal store 5 outer clean-out doors 8 that are provided with, coal store 5 communicates with the hybrid combustor 13 of body of heater mid portion, in another part space of body of heater water pipe 14 is housed, and communicates with hybrid combustor 13, around the water pipe 14 is water-cooling wall 19, and the body of heater lower end is provided with blower fan mouth 10 and deep bead 17.

The top of hybrid combustor 13 has kitchener mouth 2, can heat up water as required and cook or warm oneself, and hybrid combustor 13 belows are provided with flame height and adjust plate 12, can adjust flame height as required,
