The utility model is characterized in that the interior of the fume venting body adopts the heating form of a three back structure; the exterior of the fume venting body has a fume sleeve (10) which is communicated with the passage of the blower and is respectively provided with an air control valve (11) and a fume division passage (8); the water outflowing pipe (4) is welded on the casing of the fume venting body; the water inflowing pipe (5) is welded on the casing of the combustion chamber; the boiler door of the base holder adopts an air division structure.
Description
A kind of hot blast power economized boiler belongs to heat-exchange device.
Long in the northern China cold district warming phase, adopt the unification heat supply heating except that office building, Civil apartment in cities and towns, the resident who lives at one-storey house adopts conventional cold wind burning boiler to burn coal or timber heating mostly, the subject matter of using this heating system to exist is that the thermal efficiency is low, wastes energy.
The purpose of this utility model provides a kind of employing hot blast burning, promptly saves the energy and improves the thermal efficiency, reduces environmental pollution, and easy again a kind of hot blast power economized boiler of making and installing is to solve the drawback that exists in the prior art.
The utility model is achieved like this, a kind of hot blast power economized boiler, mainly by the base of blower fan and connection with it and the combustion chamber (2) of base (1) top, discharge fume 3 bodies, water injection pipe (5), outlet pipe (4) is formed, it is characterized in that: adopt three to return the form of being heated in the smoke evacuation body, in the smoke evacuation external body sealing cigarette cover that communicates with blower fan is arranged, cigarette puts and is respectively equipped with air control valve (11), divide cigarette channel (8), on the shell of outlet pipe (4) welding smoke evacuation body, water injection pipe (5) is welded on the combustor outer casing, and the base fire door adopts and divides the wind structure.
Blower fan of the present utility model is installed in the dead astern of base fire door.
It is cuboid that smoke evacuation body three of the present utility model returns structure.
Be provided with combustion wall again in the combustion chamber of the present utility model in addition.
Base fire door of the present utility model divides the wind structure to be: other three limits are and become 80 ° of horn mouths outside the angle with level except that the bottom in base fire door inboard.
Be provided with the heating wing in the cigarette cover that smoke evacuation body of the present utility model communicates with blower fan.
A kind of hot blast power economized boiler compared with prior art has higher energy-saving effect, main operation principle is to utilize the cigarette waste heat to add the fresh air mixing by fan passage hot blast to be blown into hot blast from base fire door dead astern, produce burning again by combustion wall, utilize the high characteristics of hot blast oxygen content, make fully burning in the stove, promptly save the energy and improve the thermal efficiency again, reduce environmental pollution.
Accompanying drawing has provided a kind of embodiment of hot blast power economized boiler.

Below in conjunction with accompanying drawing, the energy-conservation stove of a kind of hot blast is described further.
A kind of hot blast power economized boiler, base (1) smoke evacuation body (3) all can be welded with sheet metal, the wall of combustion chamber (2) is used the titanium scutum or the nodular cast iron plate is made, outlet pipe (4) is welded on smoke evacuation body (3) top, water injection pipe (5) is welded on suitable position, combustion chamber (2) according to particular location, air control valve (11) is installed in the top of smoke evacuation body (3) near outlet pipe (4), and smoke regulating valve (9) is located at the below of branch cigarette channel (8).
Conventional boiler combustion utilizes cold wind, and the hot blast power economized boiler is the heating of employing fresh air, according to the furnace temperature situation, surplus cigarette is sucked back mixing again, and burning reaches uniform temperature, is optimum state when producing the orchid fire.Principle is: when the hot blast power economized boiler uses; fuel is (2) internal combustion in the combustion chamber; heat energy is transported in the smoke evacuation body (3); adopt three to return the form of being heated in the smoke evacuation body (3); each water route is fully heated; in smoke evacuation body (3) the place ahead a flue gas cover that communicates with fan passage is arranged; open air control valve, fresh air is welded in the heat that absorbs in the cigarette cover (10) in the smoke evacuation body (3) with iron plate by certain distance exactly by the described heating wing of heating wing in the cigarette cover, with fresh air and the heating of surplus cigarette; send into base by blower fan and divide the wind furnace door gear; make heat divide uniform distribution to send into combustion wall again, combustion wall places in the combustion chamber, and wall has several air vents; because hot blast oxygen content height; can make fully burning in the stove, when the body of heater water temperature reaches 70 ℃, ature of coal waste heat (black smoke) can be removed; thereby the minimizing air pollution, the protection environment.Because the fuel combustion of hot blast power economized boiler is thorough, it is about 30% to save the energy than conventional boiler, can produce social benefit widely.
Because the hot blast power economized boiler can be made various sizes according to room for building area of heat-supply service, is not limited only to civilian house, also can supply with medium-sized and small enterprises' factory building and use, this boiler is welcome by northern resident deeply, has certain popularization value.
