Patent ID: 8667912

Claim:
A burner for highly caking coal in which a solid fuel channel that is attached penetrating through a furnace wall of a gasifier for gasifying a highly caking solid fuel that has been pulverized into particles and that supplies the solid fuel into the gasifier by gas flow transportation, and a gasifying agent channel that supplies a gasifying agent into the gasifier are provided in a concentric double pipe structure, wherein a blockage situation detection means that detects a blockage situation of the solid fuel channel is provided, wherein a temperature of the solid fuel is reduced when the blockage situation detection means detects a predetermined blockage situation, wherein the blockage situation detection means detects a differential pressure between a burner inlet of the solid fuel channel and a suitable place located downstream from the burner inlet, and judges that a blockage situation is detected when a flow loss coefficient converted from the differential pressure increases to at least a predetermined value, and wherein the temperature of the solid fuel is reduced on the basis of, in combination, an output of a control signal for increasing an amount of a carrier gas used for the gas flow transportation, and an output of a control signal for decreasing a temperature of the gasifying agent.
