Description

Energy-efficient smokeless combustion device

Technical field

The utility model relates to the burner of a kind of coal and firewood, wooden fuel.

The combustion system of usefulness such as existing miniature boiler, home furnace energy device is to make fuel be able to continuous burning from the air (oxygen) that the below of the below of fuel or perhaps burner hearth is supplied with without preheating basically.Constantly entering in the process of burning owing to cold air, the continuous discharge of hot-air, cause burner hearth internal combustion central temperature to reduce, cause burning velocity to descend, fuel decomposition is not thorough, simultaneously, the coal gas that fuel decomposition produces, fuel gas such as hydrogen are because of can not get sufficient oxygen combustion, and a large amount of combustible particles cause a large amount of black smokes or blue or green cigarette along with flue gas is arranged to atmosphere.Such burning result will cause the significant wastage of the low and thermal efficiency of efficiency of combustion.

People have also designed some novel smokeless flame stove and accessorys in recent years, as China Patent No.: 01240156.0 " flame-jetting stove ".This flame-jetting stove is made up of more than 40 parts, and the characteristics of the maximum of device are burner hearth can be hedged off from the outer world, and have avoided cold and hot air exchange, so, had than much progress than the burner of traditional cooking stove, but still existed following shortcoming:

1. this flame-jetting stove when on fire, still has long period of time to smolder by the black furnace kitchen range, only when whole furnace temperature is higher, just can reach smokeless state.

The preheating time of cooking stove long because cooking stove is in when burning, each parts must burn to aglow, so, still wasted some fuel.

3. the fuel of this cooking stove is once the firewood of vertical input " scale ", when needs add fuel midway, need remove a plurality of parts such as stove and accessory, nozzles, fire dish, adds fuel to reinstall later on extremely dangerous and trouble again.If open fuel port midway, because this cooking stove is pressure combustion, flame will spray from charging aperture, causes contingency easily.

4. during the burning of this cooking stove, can produce a certain amount of tar, directly be emitted on indoorly, living environment has been caused pollution.

5. parts are too much, manufacturing equipment costliness, processing cost height.

6. use inconvenience, can grasp complicated using method through short-term cultivation.

The purpose of this utility model is in order to overcome existing shortcoming, provide a kind of manufacturing simple in structure, easy, easy to maintenance, can be used for differently separately with the high smokeless combustion device of efficiency of combustion that can device, and can be widely used in various industrial furnaces and the domestic life cooking stove.

Technology contents

The purpose of this utility model is achieved through the following technical solutions: energy-efficient smokeless combustion device comprises blower fan, blast pipe, body of heater, burner hearth, be characterized in that at body of heater be double-decker, skin is a housing, internal layer is a burner hearth, internal layer has air vent, center-aisle outer and internal layer is an air loop duct, and the internal layer burner hearth bottom has base plate.

The air vent of the above smokeless combustion device is a row or number row.

The burner hearth bottom base plate of the above smokeless combustion device can be made the form of taking apart, can lay refractory masses, also can lay movable fire grate.

The air loop duct shape of the above smokeless combustion device can be circle, rectangle or other geometry.

The body of heater of the above smokeless combustion device can be that monoblock cast forms, and also can be that skin, internal layer are made separately with metal material, is welded with top cover and bottom up and down.

The blast pipe of the above smokeless combustion device can be located at bottom of furnace body, also can be located at the body of heater side.

The above smokeless combustion device is provided with the breach that adds fuel for the convenient fuel that adds on the side of body of heater.

The above smokeless combustion device, body of heater is outer can be provided with the UTILIZATION OF VESIDUAL HEAT IN water tank.

Principle of the present utility model is: the needed air that burns is all supplied with by these apertures, the size of aperture will be different and definite according to the kind of the size of stove device, fuel with height, aperture should be over against the combustion reaction center of burner hearth, air is after the blower fan pressurization, flow to air loop duct by blast pipe, in air loop duct, absorb heat and after preheating, be ejected into combustion centre red-hot in the burner hearth by air vent, like this, the fuel gas that produces in portion of air of sending to and the burner hearth is mixed into one, carries out completing combustion; Another part then under the pressure of blower fan, is injected on the red-hot fuel surface, directly participates in gasification reaction, and having made it endlessly, fuel gas produces.The refractory material of burner hearth bottom then helps improving the temperature of burner hearth, for burning provides advantage.The quantity combusted of this device is adjustable, and when strengthening air quantity, the air capacity that arrives fuel bed increases, and the fuel gas of generation also increases, and burning velocity is just accelerated; Vice versa.

The utility model compared with prior art has the following advantages:

1. burning reaches smokeless state fully, the flame temperature height, and heat transfer rate is fast, can significantly improve the thermal efficiency of cooking stove.

2. can improve the quantity combusted of unit volume burner hearth.

3. simple in structure, small investment, safe and reliable, easy-maintaining.

4. wide adaptability can be used for Civil energy-saving cooking stove, also can be used for small-sized boiler for domestic.

5. fuel can add at any time, is easy to observe, and is easy to use.

6, body of heater is outer as the UTILIZATION OF VESIDUAL HEAT IN water tank is set, and the utilization rate of its fuel can improve greatly.
