摘要
In a burner for highly caking coal in which a solid fuel channel and a gasifying agent channel are provided in a double pipe structure, a temperature increase of the particles of a highly caking solid fuel due to heat transfer in the burner and the resulting fusion and expansion of the particles are prevented or suppressed, thereby enabling a stable operation of the gasifier. In a burner 12 for highly caking coal in which a solid fuel channel 13 that is attached penetrating through a surrounding wall 11 of a gasifier 10 for gasifying a highly caking solid fuel that has been pulverized into particles and that supplies the solid fuel into the gasifier 10 by gas flow transportation, and a gasifying agent channel 14 that supplies a gasifying agent into the gasifier are provided, a blockage detection unit 20 that detects a blockage situation of the solid fuel channel 13 is provided, and a process for reducing the temperature of the solid fuel is performed when the blockage detection unit 20 detects a predetermined blockage situation.
