ABSTRACT:
Retorted shale particles are recovered from a retort and delivered to a gas lift for transport to a fluidized combustor by passage, serially, through a sealing vessel, a crusher preferably operating at retort pressure, and a surge vessel. In the sealing vessel, a sealing gas is introduced, and after commingling with the shale, the gas passes countercurrently to the shale and enters the retort, thus sealing the retort gases in the retort while separating the retorted shale from the retort gases. Retorted shale from the sealing vessel is transported to a crusher, wherein the shale is reduced in size to that suitable for combustion under fluidized conditions. To prevent the crushed shale from packing, the shale is passed to a surge vessel, wherein the crushed shale is held as a fluidized bed, from which the crushed shale is continuously withdrawn at a regulated rate and introduced into the gas lift leading to the fluidized combustor.
