<p>A process for the gasification of carbonaceous fuels, for, inter alia, the production of chemicals and/or the generation of power is described, characterised in that there is employed, as starting material or part thereof, coal in the form of an aqueous slurry, the aqueous (water) content of the said slurry being at least 55 to 80 % by weight. There is also described an apparatus for the burning of carbonaceous fuel, for the production of electrical energy, which apparatus comprises, in interconnected combination, a gasifier into which aqueous coal slurry is introduced, a flow drier/separator wherein materials exiting the gasifier are dried and separated into gaseous component and dried slurry material with feeding of the latter back to the gasifier, a cooling/cleaning device into which the gaseous component from the separator passes and from which, when cleaned, it proceeds for further processing, a gas turbine generation unit in turn comprised of compressor, expansion stage, and generator, and a combustor mechanism; the arrangement being such that combustion and process air passes from the turbine compressor in one stream to the gasifier and in another stream to the combustor, where the latter is combined with the gaseous component from the cooling/cleaning device, the combined gasses then being passed to the expansion stage of the gas turbine generation unit, and converted therein into electrical energy.</p> |
