Abstract
The invention relates to a high-pressure combustion environmental-friendly energy-saving boiler solving the common technological problems that the prior coal-burning boiler can not fully burn coal, in particular faulty coal, and generated waste gas and flue gas exceed the exhaust standard and are easy to be slagged in a hearth so as to pollute the environment, directly influence the service life of the boiler, and the like. Two or more parallel combustion chambers are communicated by a flue, and oxygen is transmitted and pressure is added by a blower so that high-pressure explosion-type combustion is generated in secondary combustion, comburent is fully combusted, energy sources are saved, and the discharge of contaminants, such as waste gas, duct, and the like, is lightened. The position of a circulating water pipe in a boiler body is changed so as to fully exchange heat, fully utilize the heat energy generated by the combustion, improve the heat efficiency and further achieve the purpose of energy saving and environmental protection.
Description
Technical field:
The present invention relates to a kind of burning boiler, relate in particular to a kind of high-pressure combustion environmental-friendly energy-saving boiler.
Background technology:
The various boiler main fuels that use are based on raw coal at present, but the coal-burning boiler ubiquity can not make coal-fired fully burning, especially colm is all the more so, and the waste gas and the soot emissions that produce exceed standard, and easily coking in burner hearth, contaminated environment not only, and directly have influence on service life of boiler.In addition, in burner hearth, establish the exchange water pipe merely, influence the absorption of recirculated water heat energy with the burner hearth wall, reduced the thermal efficiency, some boiler can not compatiblely use various fuel, especially is not suitable for using fuel of lower heating value, has limited the user to solid-fuelled range of choice.
Summary of the invention:
The present invention for solve present coal-burning boiler ubiquitous can not make fire coal especially colm fully burn, the waste gas and the soot emissions that produce exceed standard, and easily coking in burner hearth, contaminated environment not only, and directly have influence on the technical problems such as service life of boiler, and provide a kind of high-pressure combustion environmental-friendly energy-saving boiler, it comprises body of heater 1, bottom near first combustion chamber in body of heater 1 is provided with fire grate, on body of heater 1, be provided with fuel feed inlet, water inlet and lighting-up tuyere, below body of heater 1, be provided with slag notch, furnace wall around described first combustion chamber is the interlayer water tank, communicate with the interlayer water tank respectively at a plurality of water-circulating pipes that are positioned at above the fire grate, the interlayer water tank is communicated with water inlet; Side at body of heater 1 is provided with at least two exhaust gases passes, and communicates with second combustion chamber of body of heater 2 arranged side by side by exhaust gases passes, is communicated with the interlayer water tank of body of heater 2 by the interlayer water tank of water pipe with body of heater 1 between two bodies of heater; Be positioned at a plurality of water-circulating pipes of body of heater 2 second combustion chambers and the delivery port on the body of heater 2, water return outlet communicates with the interlayer water tank respectively; In the cavity of body of heater 2 bottoms, be provided with air blast and lead in the body of heater 1; On described body of heater 2, also be provided with floss hole; The height of second combustion chamber of described body of heater 2 is higher than the height of first combustion chamber of body of heater 1.
Characteristics of the present invention and beneficial effect: product structure is simple, easy processing and fabricating, and cost is low, efficient, energy-saving and environmental protection.
Utilize at least two high-pressure combustion equipment arranged side by side, make fire coal especially colm and bio-fuel (as the fuel that forms with compactings such as stalk, rice husk, house refuses), black smoke that combustible produced in the combustion process in the first time in boiler and smog are under high temperature action, convert fuel gas such as bituminous coal gas to, wind-force through air blast enters second combustion chamber again, by the oxygen therapy pressurization, produce the high pressure explosive combustion, fuel gas such as bituminous coal gas are fully burned, make the recirculated water quick heating, the thermal efficiency is up to more than 85%, and up to standard through the check fume emission;
Body of heater of the present invention has not only been taked the insulation measure, and by changing the position of circulating water pipe in the body of heater, makes exchange heat abundant, recirculated water is fully absorbed heat energy in water tank, reduced scattering and disappearing of heat effectively, improved the thermal efficiency, thereby reached the purpose of energy-conserving and environment-protective;
The present invention has broken away from the required chimney stalk of common coal-burning boiler, reduced the volume of boiler, can use various fuel, especially be fit to use fuel of lower heating value, widened the range of choice of user to fuel, greatly reduce heating cost, improved firing rate, reduced about 40% than the integrated cost of conventional boiler;
Behind filling fuel of the present invention, automatic combustion reaches 24 hours under unattended condition, even the longer time, not only can save a large amount of energy, and saves artificial;
Because the present invention can make fuel combustion abundant, therefore remaining residue is few, is difficult for coking in the burner hearth, has prolonged the service life of boiler, has brought convenience to ash disposal work, has reduced the pollution to environment simultaneously.
