Description

Air heating and water supply double-purpose coal-saving boiler
Technical field
The application belongs to boiler, relates in particular to heating boiler.
Background technology
No matter present various heating boiler steam heating or hot-water heating, all be manufacture hot water or steam, realize heating by the radiator circulation, its structure all is made up of combustion chamber, the bottom of a pan, double-deck furnace tube, lagging casing, water inlet, water outlet (vapour) mouth and water pipe furnace grate etc.Its water pipe furnace grate is arranged in the combustion chamber, and the combustion chamber is by the straight-through high chimney of flue.Around the combustion chamber double-deck furnace tube is set, perhaps in flue, establishes tubulation interchanger increase heat exchange effect and make full use of heat energy.Above-mentioned boiler, coal be directly burning in the combustion chamber, goes back the sufficient gas of unburned and promptly drains from flue and enter atmosphere, and heat utilization ratio is less than 30%, the combustion gas atmosphere pollution.In addition, above-mentioned heating system all be unable to do without radiator, and complexity is installed, and takes up room, and is difficult to maintenance in case leak.And the water pipe furnace grate endotherm area is little, and a large amount of heat energy also is not absorbed promptly drains from flue hurriedly, and the heat exchange weak effect wastes energy.And bulky, need fireman's specialized operations.
Summary of the invention
The application's purpose is, overcomes the deficiency of above-mentioned hot water heating, and a kind of hot-air heating coal-saving boiler is provided.
The application comprises fire door, fire door, fire grate, furnace bottom, lagging casing.Its feature also comprises, double-deck inner water sleeve and double-deck external hot air cover have water inlet and go out vapour (water) mouth on the double-deck inner water sleeve, and the inner chamber of inner water sleeve is the coal storage vaporizer, and the coal furnace mouth of adding is arranged at coal storage vaporizer top, adds coal furnace mouth and establishes closed furnace door; Coal storage vaporizer bottom is a fire grate, constitutes flame between fire grate and the furnace bottom and generates the chamber, and furnace bottom is established the deashing fire door, and the deashing fire door is established closed furnace door.Coal storage vaporizer and flame generate the chamber and respectively establish the air blast subchannel, establish air door in the passage, and air door generates constant pressure wind and oxygen supply by the outer air blast of stove to coal storage vaporizer and flame by solenoid control.Refilling double-deck hot blast cover on the double-deck inner water sleeve, forming between flame combustion between inner water sleeve and the hot blast cover, the end opening between flame combustion generates the chamber with the fire combustion and communicates, and the outlet between flame combustion communicates with outside atmosphere by blast pipe; One side lower part of double-deck hot blast cover has blast inlet, and opposite side top has hot-blast outlet.Establish scavenge trunk at coal storage vaporizer top and be connected with blast pipe, establish the ventilation door in the scavenge trunk, the ventilation door is by solenoid control open and close state.On double-deck external hot air cover outer wall or go out vapour (water) and mouthful establish temperature controller, temperature controller is connected on the controller, control air blast and each magnetic valve.When being in low-temperature burning, the closed energising of temperature controller is opened air blast automatically and is pressed wind and close scavenge trunk ventilation door automatically, guarantees to press wind not overflow in air-exchanging chamber; And open the air blast subchannel to coal storage vaporizer and the oxygen supply of flame generation constant pressure gas.The temperature detect switch (TDS) contact disconnects when reaching design temperature, closes air blast subchannel air door, stops to press wind and oxygen supply, opens the ventilation door simultaneously, and the coal storage system air chamber of making is in " anthracite " and stops to make gaseity, continues heating by waste heat in the stove.
The application also is processed with lagging casing, prevents the body of heater heat radiation, the waste resource.
When the application uses, fill it up with coal (will have part lump coal to be beneficial to ventilation) from adding coal furnace mouth, seal all fire doors, turn on the power switch with the temperature setting switch air blast and open, to coal storage gasification constant pressure wind, the fire in a stove before fuel is added produces fuel gas with the heating of upper strata coal gradually in the stove, fuel gas generates the chamber burning at flame, the arm of oxygen supply simultaneously infeeds comburant oxygen, thermal-flame enters between flame combustion, the water of inner water sleeve fully absorbs heat and generates the steam discharge or generate boiling water (hot water), and the normal temperature wind that air blast blows into is discharged hot blast from air outlet after the heating of hot blast cover.Hot blast provides hot blast through place or the drying machine that ventilation shaft leads to heating.According to setting furnace temperature, boiler moves automatically.
During first the igniting, repave one deck spunk at fire bars upper berth one deck coal earlier, light firewood and close fire door, opening power is to the vaporizer air blast.Just add the coal temporary transient blowing out in back of igniting, coal is filled it up with to be put into operation again.The ashes that spoil on the regularly blowing out removing fire grate in service and flame generate the bottom, chamber prevent to stop up the lower inlet between flame combustion.Because coal is at the vaporizer generation fuel gas that reddens of peeling from level to level, remaining ashes fall into furnace bottom automatically pressing under the wind power, so in servicely disclose stove without poker.
The application can be used for various uses such as steam, heating, bathing, drinking water simultaneously.Steam (vapor) outlet and hot air duct are connected during heating, can keep the humidity of Heating Room to prevent indoor seasoning, and this heating system is simple, as long as air supply line is led to the room, save radiator and exempt the trouble of leaking.
Because the application adopts the closed oxygen theory of combustion of joining, fugitive constituent that all combustibles produce and smog (CO in combustion process 2, NO etc.) all by thermal-flame gasification, and combustion again, become heat energy, finally reach waste gas emission standard.Again owing to adopt hot blast cover heating cold wind, enough big of cooling surface area maximizes the use heat.Both integrate, and can save coal more than 40% than existing coal-burning boiler.
