Abstract
The utility model belongs to the technical field of combustion furnaces, relates to a fuel gas infrared combustion furnace, and particularly relates to a fuel gas infrared combustion furnace without an air door, which comprises a stove head (1) and an air guide pipe (2), wherein the air guide pipe (2) comprises a pipe body (24) and an air inlet (25); the air inlet (25) is of a total-opening type; the pipe body (24) is of a straight-cylinder shape; and the inner diameter of the pipe body (24) is 70-120mm. According to the fuel gas infrared combustion furnace without an air door, provided by the utility model, the area of the air inlet is remarkably increased, a control air door is canceled, the fuel gas is burnt above a tempering critical point with certain width, the tempering phenomenon is avoided, the oxygen quantity can be increased to realize sufficient combustion, the disadvantages can be solved, the energy is saved, and waste is avoided; and moreover, the fuel gas infrared combustion furnace without an air door is simple to process and convenient to use, is green and environment-friendly, and has good application prospects in the technical field of combustion furnaces.
Description
Technical field
The utility model belongs to the combustion furnace technical field, relates to a kind of gas-fired infrared combustion furnace, relates in particular to a kind of gas-fired infrared without the air door combustion furnace.
Background technology
At present infrared gas burner burning, at the air inlet place, all design and installation a throttle setting, the size of intake during control combustion is to guarantee normal combustion.If without this device, directly supply gas firing, after furnace temperature was burnt heat, fire will be got back to air nozzle burning (being commonly called as tempering) from boiler face, perhaps fire in furnace chamber, explosion potsherd even, and can't use.Turned down intake, that is to say and reduced oxygen supply, the color of combustion ceramic sheet takes on a red color or is dark red at this moment, and output temperature is not high yet, greatly reduces the thermal efficiency of combustion gas.Compare atmospheric burning type, although energy-conservation, because infrared ceramic piece unit are quantity of heat given up is not high, be difficult to be applied at aspects such as generating, Industrial Boilers.
Summary of the invention
The purpose of this utility model is that the induced duct that overcomes combustion furnace in prior art all is equipped with air door, has reduced oxygen supply, can not fully burn, the defective that wastes energy, provide a kind of gas-fired infrared without the air door combustion furnace, significantly strengthened air-admitting surface, removed the control air door, fuel gas buring is more than the tempering critical point of certain width, avoid tempering phenomenon, have and to strengthen amount of oxygen and fully burn, just can solve all drawbacks, take full advantage of heat, do not waste.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Gas-fired infrared comprises kitchen range and induced duct without the air door combustion furnace, and induced duct comprises body and air inlet, and air inlet is full open model.Significantly strengthen air-admitting surface, remove the control air door, the induced duct that just can solve combustion furnace in prior art all is equipped with air door, has reduced oxygen supply, can not fully burn, all drawbacks that waste energy.The fuel gas buring tempering phenomenon has a critical point, below the tempering critical point scope of certain width, and just can not tempering.This burner interval that the critical point just that in prior art, people use is following.But owing to having reduced air-admitting surface, air inflow greatly reduces, and makes and can not fully burn, and causes waste.The utility model discovery, more than the tempering critical point scope of its tangible certain width, can tempering yet.The utility model utilizes this burner interval just, and air inlet is designed to the large tracts of land air inlet, and is without the air door design, and a large amount of oxygen enter burner hearth, and the supply burning improves fuel gas buring efficient, energy savings.
As preferably, body is straight-tube shape.In prior art, induced duct body caliber is less, and there is the shape that narrows at the middle part, and the utility model adopts the straight tube shape, and the burner hearth that is delivered into that oxygen can be unimpeded fully burns, and avoids tempering.
As preferably, internal diameter of tube body is 70～120mm.Significantly strengthen air-admitting surface, a large amount of oxygen enter burner hearth, and the supply burning improves fuel gas buring efficient, energy savings.
As preferably, internal diameter of tube body is 90～100mm.
The utility model provides a kind of gas-fired infrared without the air door combustion furnace; The induced duct that overcomes combustion furnace in prior art all is equipped with air door; Reduced oxygen supply; Can not fully burn; The defective that wastes energy; Provide a kind of gas-fired infrared without the air door combustion furnace; Significantly strengthen air-admitting surface; Remove the control air door; Fuel gas buring is more than the tempering critical point of certain width; Avoid tempering phenomenon; Have and to strengthen amount of oxygen and fully burn; Just can solve all drawbacks; Conserve energy; Do not waste; And processing is simple; Easy to use; Environmental protection; Good application prospect is arranged in the combustion furnace technical field.
Description of drawings
Fig. 1 is that a kind of gas-fired infrared described in the utility model is without the structural representation of air door combustion furnace.
Fig. 2 is the structural representation of the induced duct of combustion furnace of the prior art.
Fig. 3 is the structural representation of the induced duct of combustion furnace of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment
Gas-fired infrared as shown in Fig. 1,3, comprises kitchen range 1 and induced duct 2 without the air door combustion furnace, and induced duct 2 comprises body 24 and air inlet 25, and air inlet 25 is full open model.
More specifically, body 24 internal diameters are 90～100mm.It is 100mm that the utility model is selected body 24 internal diameters.
As shown in Figure 2: be the induced duct of the combustion furnace of prior art, body 21 calibers of induced duct 2 are less, and there is the shape that narrows at the middle part, and air inlet 22 areas are less, and are provided with air door 23, make intake less, burn insufficient.
And the utility model, adopt large air inlet to design without air door, can realize that combustion gas plays air demand burning, on the potsherd with homalographic, can export than original majority times above heat, also just entering the fields such as power plant, Industrial Boiler for the infrared ceramic combustion technology has created condition.And can export than original much higher temperature, when originally potsherd burns, color is redness or kermesinus, and the color of potsherd of the present utility model burning is glow or red white.
In a word, the above is only preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
