Abstract
A gasification apparatus for gasifying a carbonaceous feedstock to produce raw syngas includes a gasifier in which the raw syngas flows, a heat exchanger provided inside the gasifier downstream to exchange heat with the raw syngas, a hanger pipe through which a part of water supplied from a water supply passage flows to support a load of the heat exchanger, a heat exchanger inflow passage configured to cause the water flowing out from the hanger pipe to flow to an inflow side of the heat exchanger, a bypass passage branching from the water supply passage to cause a remaining of the water supplied to the hanger pipe, a bypass valve provided in the bypass passage, and a control device configured to control, depending on a gasifier load, an opening degree of the bypass valve to adjust the water supplied to the hanger pipe and the bypass passage.
