APPARATUS FOR MONITORING SITUATION OF SLAG DISCHARGE AND METHOD OF MONITORING SITUATION OF SLAG DISCHARGE

摘要

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 (1) to be mounted in a furnace facility (50) that processes molten slag produced within a furnace (51) by dripping the molten slag from a slag hole (54) provided on a furnace bottom (52) into cooling water outside the furnace includes an underwater microphone (2) provided in the cooling water substantially equidistant from each of a pair of slag taps (55, 55) that are disposed opposite each other and that cause the molten slag to flow into a slag hole (54).
