Description

Technical Field

[0001] The utility model relates to the technical field of gasifiers, in particular to a coal lock valve guide cover. Background Art

[0002] During gasifier operation, coal must be added regularly. This process is accomplished through a circulating coal lock, which requires frequent opening and closing of the coal lock valve. The coal lock valve has a casing structure on its exterior. After prolonged operation, the casing can become deflected and become lodged in the upper valve seat, preventing the coal lock valve from opening and closing properly. This prevents coal from being added and impacts the stable operation of the gasifier. Repairing or replacing the casing requires shutting down the gasifier, which cannot be performed while the gasifier is operating. Consequently, casing failures can occasionally cause the gasifier to shut down.

[0003] Therefore, a coal lock valve guide cover is proposed. Utility Model Content
