Abstract

The invention provides a coal water slurry process burner. The burner comprises a burner body, and a burner head is arranged at one end of the burner body; a coal water slurry spray head is arranged in the burner head; a wear-resistant layer extending to the end part of the outlet is arranged on the inner side wall of the outlet of the coal water slurry spray head; and a plane formed by the wear-resistant layer and the inner side wall of the outlet of the coal water slurry spray head is a smooth surface. The wear-resistant layer is arranged on the part, washed by high-speed coal water slurry for a long time, of the coal water slurry burner, namely the inner side wall of the outlet of the coal water slurry spray head, so that compared with existing coal water slurry burners, the effective working time of the coal water slurry process burner provided by the invention is greatly prolonged. The plane formed by the coal water slurry spray head and the wear-resistant layer is a smooth surface, the coal water slurry spray head is the same as coal water slurry spray heads in shape in the prior art, that is, by adopting the coal water slurry process burner provided by the invention, the efficiency of coal water slurry sprayed by the coal water slurry spray head is basically the same as the coal water slurry spraying efficiency of existing coal water slurry spray heads.

Description

technical field [0001] The invention relates to the technical field of coal-water slurry gasification, in particular to a coal-water slurry process burner. Background technique [0002] Coal-water slurry process nozzle is the key equipment in pressurized gasification technology of coal-water slurry. Its service life directly restricts the operation cycle of the gasifier and affects the economic benefits of the enterprise. The service life of the process burner has always been the most concerned issue of the owner, and it is also the key technical core of the burner. [0003] The coal-water slurry nozzles of the existing coal-water slurry process burners mostly have an integrated structure, which uses the same material. The existing materials for making the coal-water slurry process burners are usually metal materials, such as GH188, UMCo50, etc.; however, During the long-term operation of the coal-water slurry nozzle, the coal-water slurry is sprayed from the coal-water slu...
