Abstract
The utility model relates to a coal boiler comprising a boiler and a boiler seat. The boiler periphery is packeted with a hot water jacket provided with an inlet and an outlet. The boiler centre is provided with a liner with an air inlet hole. The liner periphery is jacketed with a coal sidebar provided with a fire outlet hole. The coal side bar and the boiler inner wall are in the formation of an annular flue connected with a flame flow channel. The outlet of the flame flow channel is disposed on the upper half part of the hearth. The combustion chamber adopted in the utility model belongs to the three-dimensional combustion in which the required air is supplied outward from the coal centre field. With full combustion, the environmental pollution from flue gas can be reduced.
Description
The utility model relates to the coal-burning boiler that a kind of heat supply water is used.
The traditional type coal-burning boiler comprises body of heater, stove seat substantially, and the central authorities of described body of heater are the combustion chamber, are surrounded by the hot water jacket all around, and the hot water jacket is provided with water inlet and delivery port.The shortcoming of above-mentioned coal-burning boiler is: because fire grate at grade, the fire coal in the combustion chamber can not get sufficient burning, so not only wastes fuel, and the flue gas of discharging descends air quality because of the incomplete combustion contaminated environment.In addition, the flame in the burner hearth is walked vertically upward, is easy to run away from exhaust opening, causes heat exchange efficiency to reduce.
The purpose of this utility model provides a kind of abundance of burning, good effect of heat exchange, a kind of coal-burning boiler free from environmental pollution.
The utility model is achieved in that a kind of coal-burning boiler, comprise body of heater and stove seat, be surrounded by the hot water jacket around the body of heater, the hot water jacket is provided with water inlet and delivery port, it is characterized in that: the center of body of heater is provided with the flue of a hollow, have fresh air inlet on the surface of flue, the lower port of flue is expansion shape and strides seat on the supporting plate that has air inlet of body of heater bottom, the periphery of described flue is with a coal hurdle that has fire output hole, the two-port flare on coal hurdle abuts in the inwall of body of heater, and and inwall between constitute an annular quirk, be connected with a flame runner on the annular quirk, its outlet is positioned at the first half of burner hearth.The outlet of flame runner is provided with deflector.Be provided with a division board in the described hot water jacket, the inlet of the secondary air duct that this division board surrounded communicates with opening on the flame runner.The below of the exhaust opening on the described body of heater is provided with an annular hot water cover that communicates with the hot water jacket.The bottom of flue is connected with a collar, is inserted with dreg-discharging rod on the collar.
Improvements of the present utility model are exactly that in the central authorities of body of heater the coal of a flue that has a fresh air inlet and fire output hole to be housed mashed, make the cylindrical perpendicular center, cylinder combustion chamber that places of coal, combustion air is from the coal column central supply, having changed conventional boiler is placed on coal on the furnace bottom grate, air is by supplying with the plane combustion mode that flame heats from bottom to top down.Also be provided with secondary wind inlet on the flame runner on the described annular quirk, can make the full combustion of fuel heat exchange.
The combustion chamber that the utility model adopts belongs to stereo burning, and it is better than the plane burning, and the required air that burns is outwards supplied with from the center of coal, and flame is favourable to hot water jacket's width of cloth emitter-base bandgap grading like this, the heat exchange efficiency height.Simultaneously, flame can be burnt fully, has reduced the pollution to environment.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model sectional structure schematic diagram.
See also Fig. 1, as can be seen from the figure, the utility model comprises body of heater 10 and stove seat 14, be surrounded by hot water jacket 5 around the body of heater, the hot water jacket is provided with water inlet 11 and delivery port 27, the top of body of heater is provided with fuel fire door 3 and exhaust opening 1, this exhaust opening below is provided with the annular hot water cover 2 that communicates with hot water jacket 5, described body of heater centre is provided with the flue 23 of a hollow, its profile is seen and is resembled a rocket, fresh air inlet 22 is arranged on the surface of flue 23, its lower port is expansion shape and strides seat on the supporting plate that has air inlet 17 13 of body of heater bottom, the periphery of described flue is with a coal hurdle 6 that has fire output hole 7, and this coal hurdle is similar to a cylindrical shell, and the two-port flare of this cylindrical shell abuts in the inwall 9 of body of heater, and and inwall between constituted an annular quirk 8, be connected with a flame runner 24 on the annular quirk 8, its port of export is positioned at the first half of burner hearth 4, which is provided with deflector 26.Be provided with a division board 20 in the described hot water jacket, the inlet 18 of the secondary air duct 21 that this division board 20 is surrounded communicates with the opening 25 on the flame runner 24.The bottom of described flue is connected with a collar 16, is inserted with dreg-discharging rod 19 on this collar 16, and when needing deslagging, pulling dreg-discharging rod 19 rotates flue 23, and cinder can be discharged from the fresh air inlet on the flue 23 22.Be with air door plate 15 on the described collar 16, air door plate 15 is supported on the dreg-discharging rod 19, and an end of air door plate 15 is connected with choker rod 12.During use, open fire door 3, fire coal is put into the combustion chamber that constitutes by flue 23 and coal hurdle 6, the air inlet 17 of combustion air below flue enters flue, and enter coal combustion through fresh air inlet 22, the fire output hole 7 of flame on coal hurdle 6 enters annular quirk 8, entered the first half of burner hearth 4 by flame runner 24.The air that flame in the described flame runner 24 and opening 25 enter carries out the secondary mixing combination burning, and the flame of second-time burning forms the annular hot water cover heat exchange of swirl flame to exhaust opening 1 below through the effect of deflector 26, and last flue gas is discharged by exhaust opening 1.
