Abstract
The invention discloses a smokeless combustion boiler device, which comprises a boiler body, a fan and an air inlet pipe. The boiler body has a structure with an inner layer and an outer layer, wherein the outer layer is a shell, and the inner layer is a hearth. An annular cavity is formed between the inner and outer layers. A bottom plate is arranged at the bottom of the boiler body. A fireproof layer is arranged on the upper surface of the bottom plate in the hearth. Air vents are formed in the lateral surface of the hearth. The fan is fixedly connected with one end of a vent pipe through a flange. The other end of the vent pipe is communicated with the cavity of the boiler body. The device is simple and rational in structure, lower in cost and easy to maintain; the boiler body has the double-layer structure, and the cavity is formed between the inner and outer layers, so that the boiler body is high in heat transfer speed, complete in combustion and high in flame temperature, and reaches a smokeless state, and the thermal efficiency of the boiler is remarkably improved; the hearth of the boiler body is provided with the air vents, so that a good ventilation effect is achieved, a gas production rate is increased, and the energy consumption is lowered; and the fireproof layer is arranged in the boiler body, so that the boiler device is high in heat resistance, safe and reliable.
Description
Technical field
The present invention relates to a kind of boiler, particularly a kind of boiler smokeless combustion device.
Background technology
Boiler is a kind of energy conversion, utilize the heat energy of fuel or other energy water to be heated as the plant equipment of hot water or steam, the forms such as heat energy that chemical energy in the fuel, electric energy, high-temperature flue gas are arranged to the energy of boiler input, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.Existing miniature boiler, the combustion system of the usefulness such as home furnace energy device is to supply with the air of unprocessed preheating so that fuel is able to continuous burning from the below of fuel or perhaps the below of burner hearth basically, constantly entering owing to cold air in the process of burning, the continuous discharge of hot-air, cause burner hearth internal combustion central temperature to reduce, cause burning velocity to descend, fuel decomposition is thorough not, simultaneously, the coal gas that fuel decomposition produces, the fuel gas such as hydrogen because of can not get fully burning along with along it discharged to atmosphere, cause a large amount of black smokes or blue or green cigarette, can cause like this significant wastage of the low and thermal efficiency of efficiency of combustion.In recent years, people have also designed some novel smokeless fire spray furnace sets, but its structure is comparatively complicated, and cost is higher; Fire spray furnace set is when on fire by the black furnace kitchen range, still have long period of time to smolder, only when whole furnace temperature is higher, just can reach smokeless state, and the preheating time of cooking stove is longer, simultaneously, during existing boiler combustion, can produce a certain amount of tar, directly be emitted on indoorly, environment has been caused pollution.
Summary of the invention
It is a kind of simple in structure that purpose of the present invention just is to provide, and easily makes, easy to maintenance, and the high boiler smokeless combustion device of efficiency of combustion, can effectively address the above problem.
To achieve these goals, the technical solution used in the present invention is such: boiler smokeless combustion device of the present invention, comprise body of heater, blower fan and blast pipe, described body of heater is interior outer double-layer structure, skin is housing, internal layer is burner hearth, be provided with toroidal cavity between the ectonexine, and the bottom arranges a base plate, described burner hearth inner bottom plating upper surface is provided with flame retardant coating, the burner hearth side also is provided with air vent, and described blower fan is fixedly connected with ventilation duct one end by flange, and the ventilation duct other end communicates with the cavity of body of heater.
As preferably, described housing is cylindrical, and burner hearth is up-small and down-big truncated cone-shaped, and burner hearth is one-body molded by top cover and the housing of an annular.
As preferably, described air vent setting and evenly distributes in the same horizontal line.
As preferably, described flame retardant coating is ceramic layer.
Compared with prior art, the invention has the advantages that: the present invention is simple and reasonable for structure, and cost is lower, easy-maintaining, body of heater is double-decker, is provided with cavity between the ectonexine, make the body of heater heat transfer rate fast, burning reaches smokeless state fully, flame temperature is high, has significantly improved the thermal efficiency of boiler, and the burner hearth of body of heater is provided with air vent, ventilation effect is good, has improved gas production, has reduced energy consumption, be provided with flame retardant coating in the body of heater, heating temperature is high, and is safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, body of heater; 2, cavity; 3, blower fan; 4, base plate; 5, flame retardant coating; 6, ventilation duct; 7, flange; 8, air vent.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, boiler smokeless combustion device of the present invention, comprise body of heater 1, blower fan 3 and blast pipe, described body of heater 1 is interior outer double-layer structure, skin is housing, internal layer is burner hearth, be provided with toroidal cavity 2 between the ectonexine, and the bottom arranges a base plate 4, and described burner hearth inner bottom plating 4 upper surfaces are provided with flame retardant coating 5, and the burner hearth side also is provided with air vent 8, described blower fan 3 is fixedly connected with ventilation duct 6 one ends by flange 7, ventilation duct 6 other ends communicate with the cavity 2 of body of heater 1, and described housing is cylindrical, and burner hearth is up-small and down-big truncated cone-shaped, burner hearth is one-body molded by top cover and the housing of an annular, described air vent 8 arranges in the same horizontal line, and evenly distributes, and described flame retardant coating 5 is ceramic layer.
The needed air of boiler combustion is supplied with by air inlet, the size of air inlet will be different and definite according to the kind of the size of boiler and fuel from height, air inlet should be over against the combustion reaction center of burner hearth, air is after blower fan 3 pressurizations, flowed to the cavity 2 of body of heater 1 by blast pipe, after preheating, be ejected into burner hearth in red-hot combustion centre by air vent 8 at cavity 2 interior absorption heats, the fuel gas that produces in the portion of air of entering and the burner hearth is mixed into one, carry out completing combustion, another part is then under the pressure of blower fan 3, be injected into red-hot fuel surface, directly participate in gasification reaction, made it endlessly fuel gas generation, 5 temperature that are conducive to improve burner hearth of flame retardant coating in the burner hearth are for burning provides advantage.The quantity combusted of this burner is adjustable, and when adding Wind Volume, the air capacity that arrives fuel bed increases, and the fuel gas of generation also increases, and burning velocity is just accelerated; Vice versa.
