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 and the resulting fusion and expansion of the particles are prevented or suppressed, thereby enabling a stable operation of the gasifier. In a burner for highly caking coal in which a solid fuel channel that is attached for gasifying a highly caking solid fuel that has been pulverized into particles and that supplies the solid fuel into the gasifier, and a gasifying agent channel that supplies a gasifying agent into the gasifier are provided in a double pipe structure, the burner has a triple pipe structure including a cooling water channel that circulates cooling water between the solid fuel channel and the gasifying agent channel, and the cooling water is recovered after use.
