Abstract

The invention discloses a multi-burner coal water slurry gasification furnace. The multi-burner coal water slurry gasification furnace comprises a shell, a central combined burner and a plurality of process burners; the shell is provided with a water cooled wall and limits a gasification chamber and a chilling chamber; the gasification chamber is communicated with the chilling chamber; the centralcombined burner is arranged at the center of the top of the shell and stretches into the gasification chamber; the process burners surrounding the central combined burner are arranged at the top of the shell; and the included angle between the axis of each process burner and the axis of the central combined burner is an acute angle. According to the multi-burner coal water slurry gasification furnace of the embodiment of the invention, the central combined burner and the process burners are provided, so that the coal water slurry treatment ability of the multi-burner coal water slurry gasification furnace is improved, the fact that the process burners spray materials on the opposite water cooled wall is avoided, the effect of protecting the water cooled wall is achieved, the temperature of a burner outlet area can be reduced and the life of the burner is prolonged.

Description

technical field [0001] The invention belongs to the field of coal-water slurry gasifier manufacturing, and in particular relates to a multi-burner coal-water slurry gasifier. Background technique [0002] Existing coal-water slurry gasifiers include the following two types. One is the top-mounted single-burner coal-water slurry gasifier, which is limited by the limited coal processing capacity of a single burner under the premise of ensuring the atomization effect. At present, the maximum capacity of the top-mounted single-burner gasifier does not exceed 2000t / d. The low coal input seriously restricts the large-scale development of coal-water slurry gasifier. [0003] The other is the opposed multi-burner coal-water slurry gasifier. The burners of this gasifier are arranged oppositely in parallel, and the burners will spray the material onto the opposite furnace wall, which greatly reduces the security. Moreover, during the operation of this gasifier, the flames sprayed f...
