BLOCKING PREVENTION DEVICE FOR GASIFICATION MELTING SYSTEM AND BLOCKING PREVENTION METHOD FOR GASIFICATION MELTING SYSTEM

WIPO Patent Application WO/2018/199288

A1

Provided is a blocking prevention device for a gasification melting system (1) that performs pyrolytic gasification on an object to be treated in a gasification furnace (2) and then combusts and melts the result thereof into a slag in a melting furnace (4). The blocking prevention device for a gasification melting system comprises: slag adhesion prevention devices (13) having a slag adhesion prevention ability for preventing adhesion of slag at openings (16, 20) which may become blocked due to the adhesion of slag; image capture devices (39, 40) that capture images of the openings; and a control device (50) that includes a calculation unit that calculates the rate of change in the opening surface area of the openings using video or multiple images, captured at different times, captured by the image capture devices, and a prevention device control unit that changes the slag adhesion prevention ability of the plurality of slag adhesion prevention devices according to the rate of change.
