Problems solved by technology

Among them, the coal material nozzle in the middle is the output channel of coal water slurry (dry coal powder), which has the most serious wear and erosion. At the same time, it is also subjected to high temperature radiation in the furnace, and has the shortest service life cycle, which restricts the coal water slurry (dry coal powder) gasification device. long-term stable operation

Embodiment 1

[0023] The invention adopts INCONEL600 and YRS188 imported materials, processed, assembled and welded. The coal nozzle has a central oxygen nozzle 6 inside and an outer oxygen nozzle 7 outside. The center oxygen nozzle 6 and the coal nozzle 1 of the present invention, the coal nozzle 1 of the present invention and the outer oxygen nozzle 7 pass through an inner support plate 8 respectively. , The outer support plate 9 is connected and positioned. The front part of the coal material nozzle is a conical body 2, and the front part of the conical body 2 is connected with a support body 5 embedded with an inner bushing 3. The front port of the inner bushing 3 is a nozzle opening 4, and the inner bushing 3 is a tapered ceramic tube made of high-temperature-resistant, wear-resistant, and erosion-resistant ceramic materials.

Abstract

The invention provides a coal nozzle for coal gasifier device and coal burning device, forepart of the coal spray is a bullet with a nozzle exit, forepart of the bullet connects a supporting body with infiller and neck bush, a frontal port of the neck bush is the nozzle exit; the neck bush is a conical interlink made of refractory, wearproof and erosion resistance metal or nonmetal material. The nozzle is used for coal gasifier device and coal burning device.

Description

Technical field: [0001] The present invention relates to a coal material gasification device and a coal material burning device, and further relates to a coal material nozzle used in the coal material gasification device and the coal material burning device. Background technique: [0002] Coal water slurry (dry coal powder) pressurized gasification technology is an internationally advanced gasification technology with coal as raw material. This technology represents the direction and trend of coal chemical industry development in the world today. [0003] Coal-water slurry gasification technology is to mix coal with water and grind to obtain a certain amount of solid-containing coal-water slurry, which is transported by a pressurized pump, sprayed through the coal material nozzle and combined with the oxygen sprayed from the inner and outer oxygen nozzles. Mixed, into the gasifier for combustion. [0004] Dry pulverized coal gasification technology is to directly grind coal...
