The gas swirling state determination system () determines the quality of the swirling state of gas that swirls around the central axis. The gas swirling state determination system () includes an imaging device (), an information processing device (), and a display device (). The imaging device () captures swirling gas from a direction along the central axis to acquire a still image. The information processing device () includes a calculation unit (), a smoothing unit (), and a determination unit (). The display device () displays a determination result.

Gas swirling state determination system and gasification melting furnace

A blocking prevention device for a gasification melting system combusts and melts an object to be treated into a slag in a melting furnace after the object to be treated is converted into pyrolysis gas in a gasification furnace, the blocking prevention device including: a slag adhesion prevention device having a slag adhesion prevention capability for preventing adhesion of the slag at an opening part that may be blocked due to the adhesion of the slag; an imaging device that images the opening part; and a control device including a calculation unit that calculates a change rate of an opening area of the opening part using a plurality of images with different capturing times or a video, captured by the imaging device, and a prevention device control unit that changes the slag adhesion prevention capabilities of a plurality of the slag adhesion prevention devices in accordance with the change rate.
