Abstract

The utility model relates to a gas auxiliary igniter which is applied on an automatic fuel oil burner, wherein a flame tube and a burning air gun are integrated, a jet hole is opened on the bottom of the flame tube, a burning air tap is located on the middle portion of the flame tube, a sharp nail is arranged on the head portion of the burning air tap, an electrode insulating ceramic rod is traversed through the bottom of the flame tube and is located on the upper portion of the burning air tap, a ceramic connecting terminal is connected and fixed on one end of the ceramic rod, an igniting gap is arranged between the crampon on the head portion of the burning air tap and an igniting electrode, the sharp nail is arranged on an outlet of the burning air tap, thereby realizing the aim of rapidly igniting.

Description

The combustion gas auxiliary igniter

One, technical field

The utility model relates to a kind of combustion gas auxiliary igniter, particularly a kind ofly is applied in the combustion gas auxiliary igniter on the automation oil burner in the oilfield transportation system heat power equipment.

Two, background technology

At present, because fuel qualities is comparatively complicated, the automation oil burner adopts the mode of auxiliary firing substantially in the oilfield transportation system heat power equipment.And the combustion gas auxiliary igniter is applied on the burner of continuous operation mostly, to reduce the operating cost of heat power equipment.The electrode of combustion gas auxiliary igniter is fixed on the outside of auxiliary igniter burner inner liner, and one or two porcelain bar electrode is arranged, and certain sparking gap is arranged between the electrode tip, provide voltage by high-tension coil, the electrode sparking is held outside the combustion gas ejiction opening, the combustion gas of igniting thus, and then the Cauldron that ignites.The problem that this igniter exists is, the porcelain rod is carbon distribution easily, cause sparking not just, spark delay, cause ignition failure, cause the Cauldron detonation when serious, have influence on the continuity and the environment protecting of device security, production.The porcelain rod needs in time to clean, and electrode gap and position need accurately to adjust, and maintenance cost, labour intensity are increased.

Three, summary of the invention

In order to overcome the above deficiency that existing light oil auxiliary igniter exists, the utility model provides a kind of combustion gas auxiliary igniter, the igniting that this igniter can not only be accurately and timely, and can reach the effect of exempting from clean and maintenance, greatly reduce the burner downtime rate.

The technical scheme that its technical problem that solves the utility model adopts is: burner inner liner and gas gun body are one, and the bottom of burner inner liner has jet orifice, and the head of burner inner liner has passage; Burning valve position is at the burner inner liner middle part, and there is a spike in combustion gas mouth portion; An electrode insulation porcelain rod passes the burner inner liner bottom, is positioned at burning valve top, and an end and ceramic binding post are connected and fixed; Valve head spike has certain sparking gap with the sparking electrode, and is positioned at the outlet of burning valve, thereby reaches the purpose of rapid igniting.

The beneficial effects of the utility model are, porcelain rod carbon distribution seldom in burner inner liner, and in time rapidly, the ignition failure rate reduces greatly in igniting.

Description of drawings

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

Fig. 1 is a front schematic view of the present utility model.

Fig. 2 is a sectional structural map of the present utility model.

1. burner inner liners among the figure, 2. jet orifice, 3. passage, 4. sparking electrode, 5. insulation porcelain rod, 6. insulation porcelain piece, 7. binding post, 8. valve head spike, 9. burning valve, 10. gas gun body, 11. blast tubes, 12. intake interfaces.

The specific embodiment

In Fig. 1, jet orifice 2 has the bottom that is arranged in burner inner liner 1 of nine groups of rules, and the head of burner inner liner 1 has passage 3, supplies with the required air of burning.

In Fig. 2, insulation porcelain rod 5 passes burner inner liner 1 bottom, be positioned at gas gun body 10 tops, one end and binding post 7 are connected and fixed, and insulation porcelain piece 6 is fixed on the gas gun body 10, are installed with a sparking electrode 4 in the insulation porcelain rod 5, the tip and the valve head spike 8 of sparking electrode 4 have certain sparking gap, be positioned at 9 outlets of burning valve, gas circuit is connected on the intake interface 12, binding post 7 inserts suitable supply voltage.When burner entered ignition procedure, binding post 7 got electric, and the 9 ejection combustion gas of burning valve are caught fire rapidly and ignited, and then the Cauldron that ignites.
