Abstract

A method and apparatus are described for gasifying carbon with steam in a fluidized bed in which the heat of gasification is supplied by a recycle stream of carbon heated externally of the bed, by entrainment in a lift tube in a hot stream of combustion gases containing molten ash particles, said gases introduced centrally into the lift tube, while feeding a stream of recycle carbon into the lift tube from an annular fluidized bed so as to provide an upflowing annulus of fluidized recycle carbon initially surrounding the stream of combustion gases, characterized in that the carbon is introduced into the annular fluidized bed from a reservoir of fluidized carbon circumferentially disposed about the lift tube and contiguous with the space occupied by the annulus of fluidized char. <IMAGE>
