Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The structure of the coal-water slurry process burner provided by the present invention with long cycle service life is as follows: figure 1 As shown, it consists of an inner burner 1, a middle burner 2 and an outer burner 3 coaxially sleeved with a streamlined front end. The inner burner 1, the middle burner 2 and the outer burner 3 are fixedly connected by a welding process. Wear-resistant coatings are sprayed on the inner wall surface of the middle burner 2 and the outer wall surface of the outer burner 3 respectively.

[0023] The coating 4 on the inner wall of the middle burner is made of tungsten-based alloy powder. The components and mass percentages of FF02·01 tungsten-based alloy powder are: Co23-28%, C4-10%, W62-70% ; The thickness of the coating 4 on the inner wall of the middle burner is 0.2mm-0.6mm, and the optional range is 0.2m...

Abstract

The invention belongs to the field of coal chemical engineering of pressurized gasification of coal water slurry, in particular relates to a coal water slurry process burner with a long service life, which is used for a coal water slurry pressurized gasification furnace, and a method for manufacturing the same. The process burner consists of an inner burner, a middle burner and an outer burner, which have a streamlined front closing end and are coaxially sleeved, wherein the inner wall surface of the middle burner and the outer wall surface of the outer burner are coated with abrasion resistant coatings respectively, and because of the coating of the abrasion resistant coatings, the user performance of the process burner under severe working conditions is improved, the service life of the process burner is greatly prolonged, the operating time of the gasification furnace is prolonged, the shutdown maintenance frequency is lowered, and the factory cost is lowered.

Description

technical field [0001] The invention belongs to the coal chemical industry field of pressurized gasification of coal-water slurry, and in particular relates to a coal-water slurry process burner and a processing method thereof for a long service life of a coal-water slurry pressurized gasification furnace. Background technique [0002] The coal water slurry process burner is a key component of the coal water slurry pressurized gasification technology, and it works in a high temperature and high pressure environment. The known burner structure of the coal water slurry process is composed of the inner burner 1, the middle burner 2 and the outer burner 3, which are coaxially set from the inside to the outside and have a streamlined front closing end. High-pressure oxygen is transported through the channel and the inner channel, and high-pressure coal-water slurry is delivered through the middle channel. After the central oxygen and the coal slurry are semi-premixed, they are mi...
