Description

The utility model relates to the field of energy and can be used in tube furnaces of the oil refining industry.

A gas-oil injection burner is known (see the VNIINEFTEMASH catalog “Burners for Tube Furnaces Tsintihimneftemash, Moscow 1985, p. 20).

Known gas burner containing a gas manifold, an external annular air supply channel with injectors, gas and air mixers (see ed. St. 1086303, F23D17 / 00, 1984)

A disadvantage of the known burners is a decrease in the productivity of the burner while reducing the amount of vacuum in the embrasure of the burner (furnace furnace), i.e. burner productivity depends on the amount of rarefaction in the embrasure of the burner (furnace furnace). In addition, at low rarefaction values in the burner embrasure, the following is observed: flame suction through the annular external air channel to the nozzles installed in the gas manifold. This is due to the fact that the vacuum near the nozzle is much larger than in the embrasure of the burner.

The technical problem to which the utility model is aimed is to increase the burner productivity by eliminating the dependence of the burner on the rarefaction in the burner inlet (furnace) and eliminating the leakage of flame to the nozzles of the gas manifold.

The solution to this problem is achieved by the fact that a gas burner containing an embrasure, a housing, a gas manifold, an external annular channel for supplying air with injectors, gas and air mixers, according to a utility model, is equipped with nozzles for gas with nozzles, while nozzles are installed at the outlet of each the nozzle and nozzles with nozzles are installed in the annular channel by circumference

between injectors at the same distance from them.

In FIG. 1 - view of the burner from the embrasure. In FIG. 2 is a section along AA of FIG. 1.

The gas burner contains an embrasure 1, a housing 2, an external annular channel 3 for supplying air, injectors 4, nozzles 5 for gas with nozzles 6 installed at the outlet, located in the annular channel around the circumference between the injectors at the same distance from them, a gas manifold 7 with nozzles 8, the central cylindrical channel 9.

The gas burner operates as follows:

Gas from the manifold 7 through the nozzles 8 exits at a speed, draws air from the atmosphere and enters the injector 4, where it is mixed with air and the gas-air mixture enters the embrasure 1, at the same time, gas flows from the nozzles 6 at the same velocity into the embrasure 1. Gas-air the mixture after the injectors 4 and the gas after the nozzles 6 in the embrasure 1 is mixed with air coming from the central cylindrical channel and the outer annular channel 3 of the air. This gas-air mixture ignites in the burner embrasure and continues to burn in the torch of the radiation chamber (furnace) of the tube furnace (to hell, not showing.).

The proposed set of essential features is aimed at increasing the productivity of the burner by eliminating the dependence of the burners on the rarefaction value in ambergris, hfJOffCOcCT

Zure burners (firebox) and eliminate tshameni to the nozzles of the gas manifold.
