Abstract

The invention relates to a high-temperature pure oxygen oil gun device for utility boiler automatic stable combustion. The high-temperature pure oxygen oil gun device comprises a water wall pipe, a high-temperature pure oxygen oil gun assembly, a pulverized coal burner, a hot air box, an oxygen heater, an oxygen mother pipe and an oxygen pipeline. The pulverized coal burner is installed on the hot air box, a hole is formed between the water wall pipe and the pulverized coal burner, the high-temperature pure oxygen oil gun assembly is connected with the water wall pipe and the pulverized coal burner in the mode that the bottom of the high-temperature pure oxygen oil gun assembly is arranged into the hole in a sleeved mode, the high-temperature pure oxygen oil gun assembly is connected with the oxygen mother pipe through the oxygen pipeline, the oxygen mother pipe is connected with the oxygen heater, and the top of the oxygen heater is open. According to the high-temperature pure oxygen oil gun device for utility boiler automatic stable combustion, high-temperature pure oxygen is utilized for combustion supporting for fuel oil, white flame at the temperature higher than 2000 DEG C is obtained, oxygen is heated further through the high-temperature flame, the oxygen temperature can reach or exceed the temperature needed by pulverized coal ignition, finally, pulverized coal is ignited by high-temperature oxygen-enriched oil flame, and the excellent stable combustion effect is achieved.

Description

technical field

[0001] The invention relates to a high-temperature pure oxygen oil gun device used for automatic stable combustion of power plant boilers. Background technique

[0002] Power plant boilers often operate below the minimum load for a long time during deep peak regulation, and need to use oil guns to support combustion. At the same time, with the increasingly tense energy situation at home and abroad, power plant boilers cannot guarantee that the designed coal type is consistent with the actual coal type, resulting in poor combustion of the boiler. When it is stable, it is also necessary to inject oil to support the combustion. Therefore, the phenomenon that the current power plant boilers consume a lot of oil for stable combustion has caused a heavy economic burden to users. According to statistics, a 600MW boiler of this type averages about 400 tons of oil per year for stable combustion.

[0003] In response to this situation, my country has developed various...
