Abstract
A slag monitoring device 100 for a coal gasifier includes a slag hole camera 11 that observes a slag hole 3 from which molten slag flows out, a water surface camera 12 that observes a situation in which the slag flowing out from the slag hole 3 falls onto a water surface 5H of cooling water 5, a falling sound sensor 13 that observes a sound of the slag falling onto the water surface 5H, and a processing device 20 that determines a solidification and adhesion position of the slag based on an opening area of the slag hole 3 observed by the slag hole camera 11 and falling lines and falling positions of the slag observed by the water surface camera.
