“Burner For Highly Caking Coal, And Gasifier”

Abstract: 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, the 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 10 are provided in a double pipe structure, the burner 12 has a triple pipe structure including a cooling water channel 20 that circulates cooling water between the solid fuel channel 13 and the gasifying agent channel 14, and the cooling water is recovered after use.
