Abstract
An HRSG for fluidized bed gasification comprises a high temperature evaporator (200), a superheater (300), a low temperature evaporator (400), and an economizer (500) connected in series. The superheater (300), the low temperature evaporator (400) and the economizer (500) have a water-tube structure, and the high temperature evaporator (200) 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.
