Abstract
The utility model provides a gas burner with a high pressure head. The gas burner comprises a housing case, a gas nozzle body, a flame cover, a gas flow servo regulating mechanism, an electronic igniter, a flame monitor and a combustion-supporting air regulating mechanism. The gas nozzle body is in an annular structure, an inner ring is connected with the gas flow servo regulating mechanism, an outer ring is connected with a pre-mixer, a diffusion disc is arranged at the front end of the gas nozzle body, a plurality of through holes are arranged on the diffusion disc, the combustion-supporting air is a high pressure air with pressure which is not less than 10KPa. The gas burner with the high pressure head has the characteristic of rapid and stable burning and does not have extinguishing or fire return phenomena. The rigidity of the burning flame is good, and the shape is easy to control. The gas burner is suitable for various gas furnaces with hearth back pressure between 5KPa and 15KPa.
Description
Technical field
The utility model relates to a kind of high-head gas burner.
Background technology
In recent years, back pressure in a certain stability region, is beneficial to the inner flue gas of the stove circulation in the manufacturing technique requirent stove of some chemical industries in 5KPa～15KPa, improves the stability of temperature and pressure in the stove, satisfies the chemical products manufacturing technique requirent.During at present the existing all kinds of gas burners in home and abroad are, the low-head burner, be not suitable for the gas furnace of back pressure greater than 5KPa.
The utility model content
Its purpose of the utility model just is to provide a kind of high-head gas burner, has rapid, the stable characteristics of burning, and do not have and take off fire and tempering phenomenon, the combustion flame good rigidly, shape is easy to control.Be applicable to the various gas furnaces of burner hearth back pressure at 5KPa～15KPa.
The technical scheme that realizes above-mentioned purpose and take, comprise casing, gas nozzle body, flame cover, the servo governor motion of gas flow, ignition, flame monitor, combustion air governor motion, described gas nozzle body is a loop configuration, interior ring connects the servo governor motion of gas flow, outer shroud connects the premixer, and described gas nozzle body front end is provided with diffusion disc, and diffusion disc is provided with several through holes, described combustion air is a high-pressure blast, and pressure is not less than 10KPa.
Compared with prior art, the beneficial effects of the utility model are,
Because it is partially premixed to have adopted the gas nozzle body to be designed to, combustion gas is before catching fire, and elder generation and part air pre-mixing in blast tube spray burning again; The 2nd, burner is by the roots blower air feed, and unnecessary air emissions adjustment mechanism is set on casing.Thereby have rapid, the stable characteristics of burning, and do not have and take off fire and tempering phenomenon, the combustion flame good rigidly, shape is easy to control.Be applicable to the various gas furnaces of burner hearth back pressure at 5KPa～15KPa.

The specific embodiment
Described casing 2 porch are provided with air door 1 and connect unnecessary air emissions adjustment mechanism, described unnecessary air emissions adjustment mechanism comprises modulating motor 11, modulating motor 11 outputs connect cam mechanism 12, and cam mechanism 12 output connection traffic control valves 13 are shown in Fig. 4,5.
Described combustion air is that roots blower 14 goes out one's intention as revealed in what one says.
This device mainly is made up of parts such as casing, gas nozzle body, flame cover, the servo governor motion of gas flow, ignition, flame monitor, combustion air governor motions, by the combustion air (P of high pressure positive blower supply
St〉=10KPa) enter casing, through all entering flame cover after pressure and the Flow-rate adjustment; The fraction air enters gas nozzle body and combustion gas premix and sprays into and revolve mouth, and most of air then enters from the gap between flame cover inwall and the gas nozzle body and revolves mouth, after the electrode electric spark is lighted, and the form combustion flame.
The gas nozzle body is designed to partially premixed, and combustion gas did not mix before entering combustion head with air, and after entering combustion head, air and combustion gas are carried out partly-premixed earlier, after the ejection of diffusion disc aperture, and ignition.Secondary wind is advection wind (also can be rotation wind sometimes), can strengthen the later stage of combustion gas and force the diffusion combustion process, and combustion gas is fully burnt.
Be provided with unnecessary air emissions adjustment valve in the casing porch, to regulate combustion-supporting air quantity.
The combustion-supporting burning air of burner generally adopts roots blower to supply with.
1 burner structure feature
This kind burner is different from other, the primary structure feature of low-head burner is: the one, and the gas nozzle body is designed to partially premixed, and combustion gas is before catching fire, and elder generation and part air pre-mixing in blast tube spray burning again; The 2nd, burner is by the roots blower air feed, and unnecessary air emissions adjustment mechanism is set on casing.
2 operation principles
Combustion air (P by the high pressure positive blower supply
St〉=10KPa) enter casing, through all entering flame cover after pressure and the Flow-rate adjustment; The fraction air enters gas nozzle body and combustion gas premix and sprays into and revolve mouth, and most of air then enters from the gap between flame cover inwall and the gas nozzle body and revolves mouth, after the electrode electric spark is lighted, and the form combustion flame.In the combustion process, combustion gas and combustion air flow are implemented interlock by gas furnace load parameter conditioning signal by servo governor motion and are regulated.
