Abstract
The utility model discloses a coal-fired boiler. The coal-fired boiler comprises a boiler body, combustion chambers, fire tubes and a water cavity, wherein a first combustion chamber is arranged on the lower portion of the boiler body and opposite to an ash bin below the first combustion chamber, the first combustion chamber is communicated with an air outlet of a draught fan, a second combustion chamber is arranged on the upper portion of the boiler body and provided with a boiler door, and an air intake hole is formed in the boiler door; the fire tubes are evenly distributed between the first combustion chamber and the second combustion chamber, fire return tubes are evenly distributed among the fire tubes and the boiler body, and an air return cavity is annular, communicated with the first combustion chamber, and communicated with the outlet of the draught fan; the water cavity is formed among the air return cavity, the first combustion chamber, the second combustion chamber and the boiler body. The coil-fired boiler is used for heating water.
Description
Technical field:
The utility model relates to a kind of boiler, particularly a kind of energy-saving free of smoke coal-burning boiler.
Background technology:
Coal-burning boiler has two large problems, and the one, the thermal efficiency is lower, and the 2nd, need carry out desulfurization and dedusting, otherwise serious environment pollution, and the desulphurization cost height becomes the main cause that difficulty is promoted in desulfurization.
Summary of the invention:
The purpose of this utility model provides the high and coal-burning boiler free from environmental pollution of a kind of thermal efficiency.
The technical scheme that realizes the utility model purpose is, a kind of coal-burning boiler, comprise body of heater, combustion chamber, fire tube and water cavity and fire door, it is characterized in that: the body of heater bottom be provided with first combustion chamber with its below grey storehouse relative, grey storehouse is provided with able to turn on or off fire door, described first combustion chamber is communicated with the air outlet of air-introduced machine, described first combustion chamber is provided with able to turn on or off fire door, be provided with second combustion chamber on the top of body of heater, this second combustion chamber is provided with fire door, has air admission hole on this fire door; Be evenly equipped with fire tube between the upper head plate of described first, second combustion chamber and lower end, the two ends of described each fire tube are tightly connected with the upper head plate of described first combustion chamber and the bottom plate of second combustion chamber respectively, and are communicated with; Between described fire tube and body of heater, be evenly equipped with tempering tube, the two ends of described tempering tube are tightly connected with bottom plate and the return-air chamber of described second combustion chamber respectively, and be communicated with, described return-air chamber is that annular chamber is communicated with first combustion chamber, and is communicated with the outlet of described air-introduced machine; Form water cavity between above-mentioned return-air chamber, first combustion chamber, second combustion chamber and the body of heater, the upper and lower of this water cavity is respectively equipped with outlet pipe and water inlet pipe.
It is high and not to the remarkable advantage of airborne release flue gas that the utility model has the thermal efficiency compared with the prior art.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the utility model is described in detail, it is relative with the grey storehouse of its below that body of heater 1 bottom is provided with first combustion chamber 3, the ash storehouse is provided with able to turn on or off fire door 2, described first combustion chamber is communicated with the air outlet of air-introduced machine 10, described first combustion chamber is provided with able to turn on or off fire door 4, be provided with second combustion chamber 9 on the top of body of heater, this second combustion chamber is provided with fire door 8, has air admission hole on this fire door; Be evenly equipped with fire tube 6 between the upper head plate of described first, second combustion chamber and lower end, the two ends of described each fire tube are tightly connected with the upper head plate of described first combustion chamber and the bottom plate of second combustion chamber respectively, and are communicated with; Between described fire tube and body of heater, be evenly equipped with tempering tube 5, the two ends of described tempering tube are tightly connected with bottom plate and the return-air chamber of described second combustion chamber respectively, and be communicated with, described return-air chamber is that annular chamber is communicated with first combustion chamber, and is communicated with the outlet of described air-introduced machine 10; Form water cavity 7 between above-mentioned return-air chamber, first combustion chamber, second combustion chamber and the body of heater, the upper and lower of this water cavity is respectively equipped with outlet pipe and water inlet pipe.
Operation principle of the present utility model is, after coal knocked down in first combustion chamber igniting, close fire door, start air-introduced machine to second combustion chamber short covering gas, high temperature hot gas enters second combustion chamber by fire tube, the pulverized coal particle of not putting after-flame in the hot gas is in second combustion chamber after the second-time burning, be drawn into the air of introducing with air-introduced machine in described annular return-air chamber by air-introduced machine and enter first combustion chamber, replenish air by the air admission hole on the fire door during second combustion chambers burn, after the high temperature hot gas that is produced by first combustion chamber is absorbed by the water in the water cavity in fire tube, cooling again in tempering tube, thereby boiler thermal output of the present utility model is higher, flue gas circulates in stove substantially not to airborne release, does not need to establish chimney, more environmental protection.When the needs deashing, but open just deashing of fire door 2, should close this fire door behind the deashing.
