Description

Three air feed coal-saving stove warming stoves

The utility model relates to a kind of three air feeds heat supply stove of economizing on coal, and is a kind of small-sized hot-water heating stove.

In existing technology, a lot of heat supply stoves adopt disposable natural air feed or mechanical air supply, because coal can not completing combustion, heat energy can not utilize fully simultaneously, and environment is caused severe contamination.What therefore a lot of in recent years technical schemes adopted is the secondary air supply mode, and it is a lot of that these have been announced in Chinese patent literature.But the secondary air feed is compared than an air feed, though coal is burnt preferably and utilize heat energy, but all unresolved combustible object unburnt difficult problem in stove also has quite a few combustible object along with flue enters atmosphere, causes the waste of efficient heat and to the pollution of environment.

The purpose of this utility model is that a kind of coal that makes of design more fully burns and the novel coal-saving stove that gasifies, reduces environmental pollution.

Scheme of the present utility model is as follows: on the basis of secondary air feed, add three times air feed.That is: by table (1), stove inwall (2), furnace outer wall (15), water interlayer (16), combustion chamber (6), flue (8), gas producer (3), secondary air channel (5), an airduct (20), be used to produce the automatic liquid-feeding tube (4) of water-gas, in the body of heater that fire grate (7) is formed, the bottom of air compartment is provided with three the air feed pipes (9) that lead to combustion chamber (6) below fire grate, and on the stove inwall (2) of the below of fire grate (7) and fire grate (7) joint, fix a flaring wind scoop (14), the lower end of bell mouth ventilator (14) is provided with wind scoop plate (13), on the air port of fire grate below air compartment, be provided with air feed adjuster (12) for the third time.The outlet of above-mentioned secondary air channel (5) is arranged in the ring-shaped air chamber (21) of gas producer (3), and gas producer (3) is located at stockhole top fixedlys connected with stockhole, is positioned at the below of combustion chamber (3).The inside and outside wall of stove (2) (15) is passed in the bell mouth ventilator (14) of fire grate (7) below in the air port of an airduct (20).Above-mentioned automatic liquid-feeding tube (4) outlet is positioned at the air chamber (21) of gas producer (3), an arrival end and a titration formula automatic liquid feeder join by syringe needle (19) and flexible pipe (18), contain combustion adjuvant in the titration formula automatic liquid feeder, insert by syringe needle (19) in the rubber stopper of automatic liquid-feeding tube (4) arrival end, in order to produce water-gas.

The utility model is simple in structure, and is easy to use.Three air feed pipes that particularly are provided with and automatic liquid feeder can be to entering the air in the burner hearth and the water-gas science of carrying out is reconciled and can make an amount of air carry out Rational flow in burner hearth, so coal fully burning and gasification in stove.Realized that coal and coal gas burn simultaneously, accomplished efficient and the unification of economizing on coal.Therefore, when using the utility model, in the coal temperature and burning time more common coal improve a lot, and do not have flue dust substantially in the flue, eliminated the pollution of coal smoke to environment.Boiler ash sediment has been taked twice sealing and direct ventilation method, health, the clean when user uses, and integrate to lift and cook a meal, heat, be a kind of desirable regeneration product of small-sized household stove.

Below in conjunction with drawings and Examples the utility model is illustrated:
