Description

The two burner civil boilers of white heat gasification

Technical field

It is the normal-pressure boiler of fuel with fire coal and living beings that the utility model relates to a kind of, and fuel can fully be burnt, and thermal efficiency height, heat transfer, endotherm area are big, the two burner civil boilers of the white heat of fuel saving gasification.

Background technology

The boiler that existing market is sold all is to adopt traditional combustion method, and structure is that body of heater is arranged mostly, and the space forms the combustion chamber in the body of heater, and ventilating opening, fire grate, ashes chamber and fire door are arranged under the combustion chamber, and linking to each other with the combustion chamber is connected to smoke exhaust pipe; In the body of heater upper end fuel inlet is arranged, the stove inner combustion chamber is placed with water pipe, is connected to water return outlet and hot water outlet with water pipe.During use, by fuel inlet coal is inserted, the flue gas that coal combustion produced (heat) is to the water pipe heating, and the hot water in the water pipe enters heating system from hot water outlet, and heat radiation is after the water of return pipe turns back to the combustion chamber heating, as circulation repeatedly a bit.But the present following problem of boiler ubiquity in application: it is insufficient 1. to burn, and the discharging flue dust is big, because crater up, fuel is in the bottom, and the flue gas of generation burns insufficient to top; 2. fuel will go up that burning zone and fuel gas are isolated to be lost combustible gas in vain, also contain SO in the loss flue gas ₂Deng oxious component and pollute; 3. the terminal outlet of large-sized boiler all connects purifier at present, and involves great expense, and has increased the user installation production cost, consequently can only reduce discharging, can not be energy-conservation; 4. heat utilization ratio is low, makes heating surface area less relatively, if reach desirable heating effect, a large amount of fire coal of essential burning causes to waste energy.200920013391.5 number patent, 200920012920.X patent are applicant's development technology in recent years, but its heat-absorbing structure and combustion chamber still exist unreasonable part aspect structural design.

Summary of the invention

The utility model purpose is in order to solve many defectives that prior art exists, to provide the white heat gasification that a kind of sufficient combustion, heat-absorbing structure advanced person and heat transfer rate are fast, the thermal efficiency is high, fuel saving need not cleaner again two burner civil boilers.

The technical solution of the utility model is for achieving the above object: the two burner civil boilers of a kind of white heat gasification, comprise body of heater, the gas outlet, charge door, fire grate, the ash chamber, combuster, transfer the wind oxygen supply port, crater, the oxygen supply combustion mechanism of forming, water jacket is arranged, the heat-absorbing body that intake-outlet is formed, top of combustion chamber is provided with charge door, fire grate bottom below the combustion chamber is grey chamber, on the fire grate of body of heater bottom, lead to the combustion chamber and be provided with oxygen supply port, it is characterized in that: the combustion chamber is positioned at the heat-absorbing body sidepiece, be respectively equipped with crater in the upper and lower, combustion chamber and reach crater down, on, the end of following crater is respectively to go up the gas outlet to reach gas outlet down, on, following gas outlet is positioned at the end face of sidepiece heat-absorbing body; Described heat-absorbing body is to surround arc furnace water jacket, at the adjacent small ash chamber that is provided with grey chamber of bottom water jacket, is provided with the partition water jacket between grey chamber and the small ash chamber.

Utilize the utility model can make fuel reach secondary up to thorough burning: the main gas component that burning first produces is carbonaceous gas, carbon monoxide, hydrogen; Burning for the second time, with regard to thorough all combustibles of after-flame of energy, the utility model compared with prior art has the following advantages:

1, energy-saving and emission-reduction.Fuel combustion is abundant, and energy transformation ratio can reach 98%, and more energy-conservation 60～70% than conventional boiler fuel saving more, the airborne release flue dust reduces discharging more than 95% than conventional method, reaches direct reduction of discharging, need not to install additional dedusting and purifying device;

2, burning, heat-absorbing structure advanced person.Adopt double-fire channel to help adjusting flue gas and prevent excessive; The oxygen supply equilibrium can be adjusted oxygen supply automatically; Burning is fierce, and thermal discharge is big, and temperature rises fast;

3, the fuel utilization is extensive.This boiler is mainly made fuel with living beings such as straw briquetting, firewood, excrement of animals, coal and solid-state combustible, its project organization is simple, volume is little, cost is low, be easy to promote the use of, be applicable to uses such as the dual-purpose family of villages and towns in rural areas a heatable brick bed, radiator, the heating of group unit, cooking, bathing.

The specific embodiment

Below in conjunction with accompanying drawing the utility model specific embodiments is described in detail.

Shown in Fig. 1～3: combustion chamber 1 is positioned at the heat-absorbing body sidepiece, 1 top, combustion chamber is provided with charge door 8, fire grate 15 bottoms below the combustion chamber are grey chambers 12, the ash chamber outer wall is provided with shoot door 4, on the fire grate 15 of body of heater bottom, lead to the combustion chamber and be provided with oxygen supply port 3, be respectively equipped with crater 2 in the upper and lower, combustion chamber and reach crater 10 down, the end of last crater 2 is to go up gas outlet 9, the end of following crater 10 is following gas outlets 13, on, following gas outlet is positioned at the end face of sidepiece heat-absorbing body, is provided with to regulate plate 7 in the jacket pipe of gas outlet 9 is led on last crater 2 opposites; Whole body of heater is surrounded by the heat absorption water jacket, and this furnace water jacket 6 is arc; At bottom water jacket and the grey chamber 12 adjacent small ash chambers 11 that are provided with, be provided with partition water jacket 14 between grey chamber 12 and the small ash chamber 11, small ash chamber 11 sides are provided with air register 5.

When fuel is sent to from charge door 8 after combustion chamber 1 lights, flame enters the exhaust passage from following crater 10, enter a heatable brick bed from the gas outlet again, oxygen in the combustion process enters from oxygen supply port 3, charge door 8, shoot door 4, abundant to guarantee oxygen supply, can regulate three places oxygen supply ratio as required, so that the control combustion intensity reaches optimum efficiency; Flame enters in a heatable brick bed a heatable brick bed is burnt heat, and the heat of water jacket absorption on every side makes the water circulation heating.When closing air-introduced machine, because draft is too big, flue gas leaks easily, can open the adjusting plate 7 at crater 2 places, makes unnecessary flue gas enter the flue of a kang, utilizes top, combustion chamber heat as need, also can open plate; Can suitably adjust the intake of air register 5 according to combustion position,, control burning velocity with regulation and control discharge duct draft, but the also shoot door of double as small ash chamber of air register.
