Abstract
The utility model relates to a jet for a coal gas burner. The utility model is mainly composed of a coal gas jetting nozzle, an air cover and a further jetting pipe. The air cover and the further jetting pipe are combined by bolts. The coal gas jetting nozzle and the air cover, and the further jetting pipe and a burner body are all combined by using screw threads. The jet is connected with the gas burner body in series. The second jet can be realized in use, and premixing air quantity which is required by the high efficiency burning of the coal gas is sucked in. Thus, the use efficiency of a Civil gas-burning stove an atmospheric burner is raised, and the CO content in exhaust air is decreased.
Description
The utility model belongs to the parts of combustion apparatus, particularly a kind of injector that is used for gas-cooker or atmospheric burner.
At present, used burner is a kind of air suspended type gas burner on the commercially available civil gas stove, also claims air suspended type to burn and chews.It is made of parts such as gasburner, air door, body and fire lids.Coal gas locates to form negative pressure with the spout ejection of certain flow rate from gasburner at the inlet (aditus laryngis) of body, sucks air.Sucking air capacity is regulated by air door.Inhaled air and the coal gas that sprays into mix in body, some apertures ejections that cover through fire then, in the kitchen range hole fire burns.The ubiquitous problem of commercially available civil gas stove is the inhaled air quantity not sufficient, gas-fired is incomplete, CO content is higher in the waste gas, flare is sent out orchid, even it is rubescent, flare does not have strength (unstable), and when calorific value of gas height (burning natural gas or oil liquefied gas) and burning big fire (coal is large-minded), this phenomenon is very obvious.The major reason that produces above-mentioned defective is that the emitter construction used of existing gas-cooker is unreasonable, and jet-action is little, can not suck the air capacity of requirement.Because the burner throat diameter is big more than gas injection device injection diameter, be easy to generate eddy current, ejection efficiency is low.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the injector that the gas burner that ejection efficiency is high is used.
The utility model by gasburner, air cap and again jet pipe three parts form.Be described in detail formation of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is used for the structural representation of burner for the utility model.
Among the figure: [1] gasburner, [2] air cap, [3] are jet pipe again. Air cap [2] and jet pipe [3] again by Bolt combination, gasburner reach jet pipe with air cap again and adopt screw thread to be combined between burner body. Air Cover and have aperture, at jet pipe device air door again, in order to regulate the air capacity that sucks. Use this practicality new The injector of type as shown in the figure. With injector of the present utility model and burner body series connection. Coal gas sprays at this Penetrate and finish a jet-action in the device, the mist of generation is from spraying the jet pipe, at the aditus laryngis of burner again The place realizes again jet-action, thus guarantee to suck realize efficient burning required be pre-mixed air capacity.
Embodiment: power is 3KW, the civil gas stove injector of the present utility model that burns natural gas.
Gasburner [1] external diameter 10mm, spray orifice 1.3mm; Have the aperture of 8 Φ 2mm on the air cap [2], with jet pipe [3] junction diameter again be 17mm; Jet pipe [3] external diameter 10～12mm again, internal diameter 6～8mm, outlet 4～6mm, the long 15～25mm of jet pipe again.After using this injector, the thermal efficiency of kitchen range is increased to 0.65 by 0.56, and CO content is reduced to 100～200ppm by 400 in the waste gas.
The novel gas burner that is used for of this reality can be realized twice injection, suck the coal gas efficient burning required give mixed air capacity, improve the use thermal efficiency of civil gas stove or atmospheric burner, reduce the CO content in the waste gas.The utility model not only can be used for the gas-cooker of natural gas, oil liquefied gas, also can be used for the burner of other coal gas simultaneously.
Claims (3)
1, a kind of gasburner and air cap of comprising is at interior gas burner injector, it is characterized in that also being equipped with on this injector jet pipe again, air cap is combined by bolt with jet pipe again, gasburner and air cap and adopt screw thread to combine between jet pipe and the burner body again.
2, gas burner injector as claimed in claim 1 is characterized in that on the jet pipe again of this injector air door being housed.
3,, it is characterized in that having aperture on the air cap of this injector as claim 1,2 described gas burner injectors.
