PROBLEM TO BE SOLVED: To provide a reliable method for detecting quenching water level to stably detect the water level of a quenching section independent of deposition of granulated slag.;SOLUTION: In a coal gasification apparatus provided with a quenching section 10 to drop molten slag flowing down from a gasification section 6 into quenching water 11 to quench and granulate the slag, the water level in the quenching section is detected by inputting detection temperatures of a plurality of thermocouples TC(1-6) arranged in vertical direction in the quenching section interposing spaces between adjacent thermocouples, selecting a pair of thermocouples adjacent to each other and having largest detection temperature difference, and judging that the water level of the quenching section is present between the pair of thermocouples. A throttle part 9 having a rectangular opening to flow down the molten slag is placed between the gasification section and the quenching section, and the multiple thermocouples are placed on a wall surface of the quenching section opposite to a long side of the rectangular opening of the throttle part.;COPYRIGHT: (C)2014,JPO&INPIT
