Integrated gasification combined cycle power plants

found: Mitchell, S.C. Hot gas cleanup of sulphur, nitrogen, minor and trace elements, 1998:p. 5 ("Over the past decade there has been significant progress in the development of new coal-based combined cycle power generation systems, such as pressurised fluidised bed combustion and integrated gasification combined cycle (IGCC) that integrate a high-efficiency gas turbine cycle with a steam turbine cycle.")

found: International Energy Agency. Coal information, 1997, 1998:p. I.90 ("already technical development and evaluation programmes in several countries have demonstrated that advanced clean coal technologies such as the pressurised fluidised bed combined cycle and the integrated coal gasification combined cycle are capable of higher efficiencies ... and an enhanced environmental performance.")

found: Clarke, L.B. Management of by-products from IGCC power generation, 1991:p. 13 ("Integrated gasification combined cycle (IGCC) power generation uses coal gasification, followed by gas cleanup, to provide fuel for a gas turbine. The hot exhaust gases from the gas turbine are used to generate steam which is used, together with the steam raised in the gasification process, to generate additional electricity in a steam turbine.")
