Abstract
A high-pressure combustion environment-friendly and energy-saving boiler aims to solve the general technical problems of the prior coal fired boiler that the coal, especially poor coal can not be fully burnt, the discharge of the produced waste gas and soot exceeds standard, and the coke is easily formed in a hearth, thereby polluting the environment and directly influencing the service life of the boiler. Two or more parallel combustion chambers are communicated through flue gas passages, a blower is utilized for oxygen conveying and pressurizing, so that high-pressure explosion type combustion is generated during secondary combustion, the combustion matters can be fully burnt, energy conservation is realized, and the discharge of pollutants such as waste gas, dust, and the like is reduced. Additionally, the heat can be fully exchanged through changing the position of an internal circulation water pipe in the boiler, thereby fully utilizing the heat energy generated through combustion, improving the heating efficiency, and achieving the purposes of energy conservation and environmental protection.
Description
Technical field:

Summary of the invention:
The utility model 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 utility model 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 utility model 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 utility model has been 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 utility model, 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 utility model 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.
