Abstract
The utility model relates to a combustion device; in particular to a coal-fired furnace. A master hearth port and an auxiliary hearth port which are communicated with each other are arranged on the upper end of a furnace body. A smoke vent is arranged on the inner wall of the auxiliary hearth port. Both ends of a combustion chamber inside the furnace body are communicated with the master hearth port and an air supply cavity. An induced draft fan is fixedly arranged inside the furnace body. An air inlet of the induced draft fan is communicated with the smoke vent arranged on the inner wall of the auxiliary hearth. An air outlet of the induced draft fan is communicated with the air supply cavity. The utility model has good effect on coal saving and is lower in soot pollution. The utility model has no need of arranging an outside chimney and has simple structure and high performance cost ratio.
Description
The utility model relates to combustion apparatus, specifically a kind of coal stove.
Coal stove is used more widely in industrial and agricultural production and catering industry.The primary structure of existing a kind of coal furnace is: the body of heater upper end is provided with primary stove entrance, the secondary stove entrance of connection, has exhaust opening on the secondary stove entrance inwall, and chimney and exhaust opening join, two ends and primary stove entrance and the connection of air feed chamber in the body of heater inner combustion chamber.During its work, the flue dust that the burning back produces enters secondary stove entrance by primary stove entrance, discharges by chimney.The coal furnace of this kind structure can utilize the waste heat of flue dust preferably by secondary stove entrance.But it has the following disadvantages: flue dust is directly discharged by chimney after by primary stove entrance and secondary stove entrance, contains a large amount of unburnt combustible dusts in the flue dust, has promptly polluted environment, has caused the waste of the energy again.
The purpose of this utility model is to provide and makes that combustible dust fully burns in the flue dust, the environmental protection and energy saving coal furnace that environmental pollution is less.
For achieving the above object, the utility model adopts following scheme: the body of heater upper end is provided with primary stove entrance, the secondary stove entrance of connection, have exhaust opening on the secondary stove entrance inwall, two ends and primary stove entrance and the connection of air feed chamber in the body of heater inner combustion chamber, be installed with air-introduced machine in the body of heater, exhaust opening on the air inlet of air-introduced machine and the secondary stove entrance inwall is connected, and the air outlet of air-introduced machine and air feed chamber are connected.
By such scheme as seen, the flue dust overwhelming majority that drains into primary stove entrance and secondary stove entrance place after the internal combustion of combustion chamber is inhaled in the air-introduced machine, is drained back to the air feed chamber and is sent into burning once more in the combustion chamber by air-introduced machine.So force circulation repeatedly, the combustible dust in the flue dust is fully burnt, be achieved the purpose of economizing smoke abatement.
The utility model effect of coal saving is good, and smoke contamination is little, does not need the peripheral hardware chimney; And simple in structure, the ratio of performance to price good.
Accompanying drawing is the structural representation of the utility model one embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
Referring to accompanying drawing, primary stove entrance 6, secondary stove entrance 3 are located at body of heater 1 upper end, and primary stove entrance 6 is communicated with by passage 5 with secondary stove entrance 3.In body of heater 1, two ends of combustion chamber 7 and primary stove entrance 6 and air feed chamber 8 are connected, be installed with air-introduced machine 12 in the body of heater, the air inlet of air-introduced machine 12 is connected by airduct 14 and the exhaust opening 2 on secondary stove entrance 3 inwalls, and the air outlet of air-introduced machine 12 is connected by airduct 9 and air feed chamber 8.Because it is higher to enter the temperature of the flue dust in the air-introduced machine 12, for preventing the motor heat damage on the air-introduced machine, with the motor on the air-introduced machine 12 12 ' with the air-introduced machine body portion from setting, motor 12 ' the pass through blade shaft of belt 13 transmission air-introduced machines 12.On the inwall of secondary stove entrance 3, be installed with the back 4 of projection.The flue dust heat wave that enters in the secondary stove entrance 3 reflects by making progress of back 4, can improve the thermal effect that adds to secondary stove entrance place cooker.In addition, also be installed with a manual blower fan 11 on body of heater 1, manually the air outlet of blower fan 11 is connected by airduct 10 and air feed chamber 8.During power failure, can be by manual blower fan 11 air blast.
