  • Slag monitoring device for coal gasifier and coal gasifier
    Patent number: 9239164
    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.

  • SLAG DISCHARGE CONDITION MONITORING APPARATUS AND METHOD FOR MONITORING SLAG DISCHARGE CONDITION
    Publication number: 20100207785
    Abstract: A slag discharge condition monitoring apparatus and a method for monitoring a slag discharge condition that are capable of preventing the detection accuracy of the slag discharge condition from being lowered due to scaling-up of a coal gasification facility, especially a coal gasification furnace, are provided. A slag discharge condition monitoring apparatus to be mounted in a furnace facility that processes molten slag produced within a furnace by dripping the molten slag from a slag hole provided on a furnace bottom into cooling water outside the furnace includes an underwater microphone provided in the cooling water substantially equidistant from each of a pair of slag taps that are disposed opposite each other and that cause the molten slag to flow into a slag hole.
