Abstract

See full text

A gasification apparatus heats and pressurizes a gasification feedstock to bring the gasification feedstock into a supercritical state, and performs decomposition-treatment on the gasification feedstock to obtain fuel gas. The gasification apparatus includes a heat exchanger, a gas-liquid separator, and a turbine. The heat exchanger introduces the gasification feedstock into a low-temperature-side flow channel and introduces treated fluid in a supercritical state into a high-temperature-side flow channel, so that heat exchange is performed between the gasification feedstock and the treated fluid. The gas-liquid separator extracts, from the high-temperature-side flow channel, the treated fluid that has been in a subcritical state due to heat exchange, performs gas-liquid separation on the treated fluid, and returns a separated liquid to the high-temperature-side flow channel. The turbine is powered by fuel gas separated by the gas-liquid separator.
