Beschreibung
Zusammenfassung:	Power generation apparatus includes air separation unit 5 producing an oxygen enriched product for supply to gasification vessel 3 which produces fuel gas by the partial oxidation of a carboniferous feedstock; a generator 20 driven by gas turbine 1 comprising air compressor 11, means for delivering a portion of compressed air to combustor 13 and expander 12 driven by combustion products from the combustor 13 and driving the compressor 11. The remaining portion of compressed air is extracted from the gas turbine 1, and may be used in expander 4 to drive generator 41. None of the remaining portion of air is feed to the air separation unit. A Clean Power Generation (CPG) facility is described (fig 4) and alternative air extraction arrangements taught (figs 5 and 6).
