Embodiment 1

[0023] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the coal gasification process burner nozzle of the present invention includes: nozzle inner wall 1 , nozzle outer wall (also called shell) 2 , runner partition 3 , water outlet 4 , water inlet 5 , and spoiler 6 . figure 2 Shown is a schematic diagram of the space structure of the flow channel separator of the present invention. Depend on figure 2 It can be seen that the flow channel partitions are in the shape of a helix, and adjacent partitions are perpendicular to each other.

[0025] Depend on figure 1 It can be seen that the nozzle at the front end of the nozzle of the present invention is ellipsoidal; the second half connected to the water outlet 4 and the water inlet 5 is cylindrical. The flow channel partition 3 forms an angle of 45° with the axis. In the cylindrical part, the adjacent flow cha...

Abstract

The invention discloses a novel coal gasification process burner jet nozzle. The burner jet nozzle is of an integral single structure, and consists of five parts including an inner wall, an outer wall, a runner separation plate, a water inlet and a water outlet, wherein the runner separation plate connects the inner wall and the outer wall. The front part of the jet nozzle is in a spherical shape,an oval shape or a conic shape; the back part of the jet nozzle is in a cylindrical shape. The adjacent runner separation plate and the inner and outer walls form a triangular runner; the runner formed with the inside is a water inlet passage; the runner formed with the outer wall is a water outlet passage; a water inlet and outlet passage is communicated with a jet head. The jet nozzle is an integral structure; the runner separation plate realizes the complex functions of separating the runner, enhancing the structure and increasing the heat conduction area. The manufacturing work proceduresof the burner jet nozzle are simplified; the welding bead is eliminated; the burner heat radiation efficiency is improved; the service life of the burner can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of coal gasification and is applied to a coal gasification process burner. Background technique [0002] With the improvement of environmental protection awareness, the clean utilization of traditional energy - coal is imminent. Coal gasification is an important direction for the clean utilization of coal. As one of the core equipment of the coal gasification process, the process burner needs to work continuously at a high temperature of 1400°C and in a sulfur- and chlorine-containing gas flame, and its service life directly affects the stability and production capacity of the coal gasification process. [0003] The process burners currently used in China are divided into coal water slurry process burners and pulverized coal type process burners. The structure of the coal water slurry process burner is inherited from the design of the American Texaco process burner, which is composed of a cooling water coi...
