Research on characteristics of MCFC-GT hybrid system based on total energy concept This paper discusses the working performance of MCFC-GT hybrid system at diffirent work conditions. The results show that the hybrid system is high efficiency but the change range of work conditions is narrow. The work condition can be extended by a variable-speed gas turbine. However, this method of operation weakens the action of bottoming cycle.
