specific Embodiment approach 1

[0005] Specific embodiment one: (referring to Fig. 1 and Fig. 2) this embodiment consists of reducing pipe 1, primary pulverized coal combustion chamber 2, fire detection probe 3, first auxiliary gasification small oil gun fixed sleeve 4, perimeter cooling Air duct 7, secondary combustion chamber straight section 8, burner outer pipe 9, secondary combustion chamber contraction section 10, first rib 11, perimeter cooling air contraction section 12, second rib 13, secondary combustion chamber Outlet section 14, the 3rd rib plate 15, the 4th rib plate 17, the 5th rib plate 18 and the oxygenation pipe 6 are made up, between the outer wall of the straight section 8 of the secondary combustion chamber and the inner wall of the burner outer pipeline 9 respectively fixed with The third rib plate 15 and the fourth rib plate 17, the inner wall of the straight section 8 of the secondary combustion chamber is provided with an annular neck 16, the outlet end of the reducer pipe 1 is fixedly...

specific Embodiment approach 2

[0006] Specific embodiment two: (see Fig. 1) The difference between this embodiment and specific embodiment one is that the second auxiliary gasification small oil gun fixed sleeve 20 is added, and the second auxiliary gasification small oil gun fixed sleeve 20 It is arranged in parallel with the first auxiliary gasification small oil gun fixing sleeve 4 and fixed on the primary combustion chamber 2 . The increased second auxiliary gasification small oil gun fixing sleeve 20 can increase the position of an auxiliary gasification small oil gun to accelerate pulverized coal combustion. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0007] Embodiment 3: The cross-section of the outlet section 14 of the secondary combustion chamber in this embodiment is circular or square. The cross-section is a circular or square secondary combustion chamber outlet section 14, which can be adapted to the specific structure of the boiler. Other compositions and connections are the same as in the first embodiment.

Abstract

The invention relates to a non-smoke gasify micro oil gun ignition powder coal burner, wherein, the cooling air cylinder (7) is arranged outside the outer tube (9) of burner; the cooling air cylinder (7) and the outer tube (9), the secondary burning room reducing section (10) and the cooling air reducing section (12) are formed by the cooling air channels (5) between them; one end of oxygen tube (6) is communicated with the secondary burning straight section (8), while another end is communicated with outer space. The invention mounts an oxygen tube to feed oxygen into the secondary burning room, to improve the oxidization speed, improve the burnt degree, and realize non-smoke burning.

Description

technical field [0001] The invention relates to a pulverized coal burner. Background technique [0002] With the development of my country's national economy, the demand for energy is increasing day by day, and the proven reserves of petroleum resources in my country are limited. At present, my country spends a large amount of foreign exchange to import oil every year. The electric power industry is a large consumer of fuel oil. According to the statistics of electric power in recent years: thermal power coal-fired units account for about 74.8% of the total installed capacity, and the oil consumption is about 2.33 million tons, accounting for 31.9% of the total oil consumption. It is mainly used for boiler startup and ignition. Combustion-supporting and stable-combustion oil during low-load operation. In order to reduce the consumption of oil resources and increase the research and development of new fuel-saving technologies for thermal power plants, the National Developme...
