Abstract

The utility model provides a fuel gas burner flame stabilizing cup. The fuel gas burner flame stabilizing cup is characterized by comprising a cup-shaped flame stabilizing cup body which is provided with a cup bottom and an upward-standing barrel-shaped cup wall at the edge of the cup bottom, a plurality of air holes are formed in the barrel-shaped wall, the barrel-shaped wall is fixed in a barrel-shaped combustion barrel, the diameter of the barrel-shaped combustion barrel is larger than the diameter of the barrel-shaped cup wall, an end portion of a gas inlet pipe penetrates through the cup bottom and then is arranged inside the flame stabilizing cup, and an end portion of an ignition bar corresponds to a stop sheet arranged at the end portion of the gas inlet pipe. According to the fuel gas burner flame stabilizing cup, a traditional plate-type flame stabilizing device is changed to be cup-type, a small stable environment is formed, fuel gas and air can pre-combust in a mixing mode inside a combustion cup, and therefore flame inside the combustion cup can not be extinguished even if pressure inside an outer combustion chamber is high or air currents inside a combustion chamber are not stable. The stable flame ensures that a burner can work consecutively and normally.

Description

The steady flame cup of gas burner system

Technical field

The utility model belongs to a kind of gas burner system accessory, relates in particular to the steady flame cup that a kind of gas burner system uses.

Background technology

Existing kitchen range generally uses the dish-type flame holder with gas burner system, belong to outer hybrid-type burning, be that combustion gas and air burn simultaneously in the combustor external mix, due to its structural defective, when the combustor external environment condition unstable, press too highly in as excessive in flow-disturbing, burner hearth, the mixed proportion that all can have influence on combustion gas and air causes combustor easily flame-out.

The utility model content

The utility model provides a kind of gas burner system steady flame cup, and its purpose solves the shortcoming that prior art exists, and gas burner system is difficult for flame-out, can steady operation.

The technical scheme that its technical problem that solves the utility model adopts is:

The steady flame cup of gas burner system is characterized in that: have a cup-shaped steady flame cup, at the bottom of steady flame cup has glass and the tubular wall of cup upwards erect of cup feather edge, the tubular wall of cup is provided with some airports; The tubular wall of cup is fixed in the tubular combustion barrel, and the diameter of tubular combustion barrel is greater than the diameter of tubular wall of cup; Be arranged on steady flame cup after at the bottom of the end of air inlet pipe is passed glass inner, the tube wall that air inlet pipe is positioned at steady flame cup inside is provided with some fuel gas holes; Be arranged on steady flame cup after at the bottom of the end of fire rod is passed glass inner, the set catch position in the end of fire rod and air inlet pipe end is corresponding.

Usefulness of the present utility model is:

The utility model changes traditional dish-type flame holder into a glass type, form a stable subenvironment, combustion gas and air burn in advance in the combustion cup internal mix, even press high in outside burner hearth, the indoor air flow that perhaps burns is unstable, also can not make the fray-out of flame of combustion cup inside.This stable flame has guaranteed that combustor can work constantly.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the utility model structure chart;

Fig. 2 is the steady flame cup of the utility model outside drawing.

The specific embodiment

As shown in Figure 1 and Figure 2,steady flame cup 1 of the present utility model is a cup-shaped steady flame cup, thussteady flame cup 1 have at the bottom ofcircular cup 13 and the tubular wall ofcup 12 upwards erect of cup edge, theends 13 form a cup-shaped object, wall ofcup 12 is provided with someairports 10; Tubular wall ofcup 12 is welded to connect with the outerperipheral flange 11 in its top and is fixed intubular combustion barrel 3, and the diameter oftubular combustion barrel 3 is greater than the diameter of tubular wall ofcup 12, thereby has the gap that can pass through for air between the inwall oftubular combustion barrel 3 and tubular wall ofcup 12; Be arranged on the inside ofsteady flame cup 1 at the bottom of theend 21 ofair inlet pipe 2 is passed glass after 13, the tube wall of theend 21 ofair inlet pipe 2 is provided with somefuel gas holes 20;Fire rod 5 is fixed onair inlet pipe 2 by fire rod fixedmount 4, is arranged on the inside ofsteady flame cup 1 at the bottom of theend 51 offire rod 5 is passed glass after 13, and set catch 22 positions in theend 51 offire rod 5 and theend 21 ofair inlet pipe 2 are corresponding.

As Fig. 1,steady flame cup 1,air inlet pipe 2,combustion barrel 3, fire rod fixedmount 4,fire rod 5 form complete burning structure.The air of coming from the combustor combustion fan forms certainblast combustion barrel 3 is inner, and air evenly enterssteady flame cup 1 inside fromsteady flame cup 1 outside by theairport 10 that distributes on the tubular wall ofcup 12 ofsteady flame cup 1 under pressure.Combustion gas enters into by the equally distributedfuel gas hole 20 in theend 21 ofair inlet pipe 2 fromair inlet pipe 2 inside thatsteady flame cup 1 is inner to be mixed with air.The spark ignition that the gas that this combustion gas mixes with air is produced by set catch 22 electrions in theend 21 of the 51 pairs ofair inlet pipe 2 in end of fire rod 5.In combustion process, even outside flow-disturbing is large, insteady flame cup 1 inside, stable flame is arranged all the time, burning is continued.

Due to relatively stable in the mixing ratio ofsteady flame cup 1 inner air and combustion gas, be subjected to the impact of peripheral environment little, Gu the combustor flameholding of this structure, strong adaptability has solved the easily difficult problem such as flame-out of the little space combustion machine ignition difficulties such as similar steamer, small-sized coating equipment combustor.
