N2 - The paper shows the results of calculations for a concept assuming the connection of the supercritical coal-fired power plant (SCPP, so-called reference unit) with the gas turbine installation and heat recovery system. The components of this system were: a supercritical heat recovery steam generator and two flue-gases heat exchangers used for preheating of condensate and of feed water. The presence of exchangers permits to replace regeneration and to obtain, in consequence, higher nominal power rating of steam turbine. For the reference unit and assumed structure of a multi-fuel hybrid cycle (MFHC) the key indicators of the thermodynamic and ecologic evaluation were defined. The researches were carried out for a defined gas turbine model, i.e. GE MS9171. In the course of investigation the levels of two defined in the paper ratios of regeneration replacement were changed. The values of thermodynamic and ecologic effectiveness obtained for two specified values of regeneration replacement ratios were compared with values of effectiveness indicators obtained for reference unit and three alternative technologies. This technologies were: supercritical coal-fired power plant integrated with CCS installation (SCPP+CCS), simple cycle gas turbine (SCGT) and combined cycle gas turbine (CCGT).
