Abstract

An HRSG for fluidized bed gasification comprises a high temperature evaporator (), a superheater (), a low temperature evaporator (), and an economizer () connected in series. The superheater (), the low temperature evaporator () and the economizer () have a water-tube structure, and the high temperature evaporator () has a fire-tube structure. The HRSG of the present invention allows efficient heat recovery from the raw syngas of a fluidized bed coal gasifier, while avoids or reduces the corrosion of and damage to the components of the HRSG caused by high-speed ash particles in the syngas.
