Abstract: The present invention relates to a gas turbine power plant wherein the gas turbine is driven by gases and steam heated indirectly through a heat exchanger by the burning of corrosive fuels. One of the main improvements in the present invention is to utilize a state-of-the-art gas turbine in the power plant.

Abstract: Apparatus is disclosed for use in the removal of molten particles from a hot gas. The hot gas carrying the molten particles is passed through a granular bed comprising, in succession, a stack of larger and a stack of smaller solids. Gas exiting the stack of smaller solids is substantially free of the molten particles. The vessel provided for housing the granular bed is adapted to allow the differently sized solids to move in their individual stacks. The vessel includes a single gas entry which is free of louvers or other permanent structural obstructions subject to clogging. The apparatus may be integrated into a coal gasification system or a combined cycle plant where a substantial proportion of the original sensible heat of the gas and of the particles is recovered for other uses.
