摘要： This invention provides a process and apparatus for gasifying a particulate solid carbonaceous fuel with a high moisture content, the process comprising: introducing the fuel into one or more pressurized drying vessels without adding water to the fuel; reducing the moisture content of the fuel in the drying vessel(s) to a level suitable for gasification by passing hot product gas through the or each drying vessel such that the fuel particles are entrained in the gas flow, thereby cooling and humidifying the gas; separating the cooled and humidified gas from the fuel; transferring the fuel with reduced moisture content from the or each drying vessel to a gasification vessel, gasifying the fuel in the gasification vessel to produce hot product gas; and introducing at least a portion of the hot product gas into the or each drying vessel. The invention also relates to an integrated process for producing power, especially electric power, from particulate solid carbanaceous fuel.
