Problems solved by technology

However, the water content of coal-water slurry is generally about 40%, so it is more difficult to realize it by using the ignition burner. At the same time, it is even more difficult to realize the structure of the coal-water slurry gasifier
Therefore, the coal-water slurry gasifier must be lined with refractory bricks, which results in increased operating costs

Abstract

The invention relates to the field of coalification process of water coal slurry pressure gasification, in particular to a water coal slurry pressure gasification process burner device with an ignition device. The burner device comprises a flange cover, a water coal slurry supply pipe, an external oxygen supply pipe, a water coal slurry pipe, a mounting flange, an external oxygen pipe and a middle flange, and also comprises a high-pressure electric igniter, execution mechanisms, an electric ignition bar, a central oxygen system and a combined seal, wherein the upper parts of an end face flange, a central oxygen pipe and the flange cover are provided with the execution mechanisms. The water coal slurry pressure gasification process burner device with the ignition device enables a water coal slurry gasification furnace with a water-cooling wall coil type inner wall to be used.

Description

technical field [0001] The invention relates to the coalification process field of pressurized gasification of coal-water slurry, in particular to a burner device for the pressurized gasification process of coal-water slurry with its own ignition device. Background technique [0002] Existing pressurized coal-water slurry gasifiers are all equipped with refractory brick linings. On the one hand, in order to protect the pressure steel shell from heat; The ignition process of coal water slurry. [0003] In general, the start-up method of the coal-water slurry pressurized gasifier is as follows: firstly, the preheating burner is used for preheating, and when the suction device downstream of the furnace is opened, the gasification furnace is guaranteed to be under the condition of negative pressure , use light fuel (diesel, natural gas, liquefied petroleum gas, etc.) to heat the gasification furnace, and install refractory bricks with sufficient thickness in the gasification fu...
