Abstract
A gasification/combustion system (10) for the gasification/combustion of non-gaseous fuels with single or combinable oxidants and sulphur sorbants is described. The system (10) includes a rotary fluidized bed gasifier (12) for gasifying a non-gaseous fuel, the outlet of the gasifier (12) being connected to a gas turbine (14) through gas cleaners (46,50) for removing particles from the fuel gas, and an afterburner (16) for burning off the fuel gas to produce combustion gases for supply to a gas turbine (14). The system (10) also includes a steam cooling circuit which is provided to cool the fuel gas flow through system (10) and which includes a steam turbine (26). Embodiments of the system (10) are described with accompanying drawings.
