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 gasification melting facility comprises: a fluidized bed gasification furnace that generates pyrolysis gas by thermally decomposing waste and discharges incombustibles; a melting furnace into which the pyrolysis gas is fed; a pyrolysis gas passage that connects the fluidized bed gasification furnace and the melting furnace; a grinder that grinds the incombustibles discharged from the fluidized bed gasification furnace by passing the incombustibles through a plurality of rods; a vibratory sifter that screens the incombustibles ground in the grinder; a fixed amount feeder that feeds at a fixed amount the incombustibles that pass through the vibratory sifter, the fixed amount feeder including a plurality of transfer chambers rotatable between a position to receive the incombustibles from the vibratory sifter and a position to discharge the incombustibles; and an airflow conveyor that conveys the fixed amount of the incombustibles from the fixed amount feeder together with airflow.
