BURNER FOR HIGHLY CAKING COAL AND GASIFIER

摘要

A burner for highly caking coal having a double pipe structure of solid fuel flow channel and gasifying agent flow channel, which burner prevents or inhibits any melting/expansion of highly caking solid fuel particles by temperature rise thereof attributed to intra-burner heat transfer to thereby realize stable operation of gasification furnace. There is disclosed a burner (12) for highly caking coal comprising, provided through a peripheral wall (11) of gasification furnace (10) for gasification of a highly caking solid fuel pulverized into particles, a solid fuel flow channel (13) for feeding the solid fuel into the gasification furnace (10) by air stream carriage and a gasifying agent flow channel (14) for feeding a gasifying agent into the gasification furnace. The burner further comprises a clogging detector (20) for detecting any clogging condition of the solid fuel flow channel (13) so that when a given clogging condition is detected by the clogging detector (20), a processing for lowering the temperature of the solid fuel is carried out.
