IMPACT OF INTER-COOLING AND REHEAT ON THERMAL EFFICIENCY OF COAL-GASIFIED STIG CYCLE[J]. Thermal power generation, 1999, (4). DOI: 10.19666/j.rlfd.1999.04.012.
Abstract Introduced in this paper is a combination of coal gasification technology used in IGCC with a steam injected gas turbine cycle(STIG)
which changes its fuel from oil to gasified coal.The STIG cycle is added with inter-cooling and reheat.Calculations of thermal efficiency are made on this coal gasified inter-cooling and reheat STIG cycle and the impace of inter-cooling and reheat on the thermal efficiency are analyzed.The conclusion is different from that of STIG cycle with oil as the fuel
that is
under the available condition at the moment
the thermal cfficiency of the coal-gasi fied STIG cycle can not be increased by the inter cooling and reheat.
