Abstract

To improve the efficiency of the shipborne gas turbine and reduce the temperature of exhaust gas

a novel waste heat recovery cycle composed of supercritical carbon dioxide regenerator Brayton cycle and organic flash cycle is proposed

in which the supercritical carbon dioxide recycles the high temperature exhaust gas

and the organic flash cycle recovers the low temperature exhaust gas. Then

thermodynamic analysis of the cycle and optimi-ation of the target function with cyclic net power are conducted. The results show that under the basic conditions

the thermal efficiency and enthalpy efficiency of the gas turbine after the waste heat recovery cycle are up to 50.4% and 68.93%

which is 44% and 43.6% higher than that of the stand-alone gas turbine cycle

respectively. In addition

the largest value of exergy loss is 842.04 kW in the condenser

accounting for 6% of the system total exergy value. When the carbon dioxide compression pressure ratio is larger and the terminal temperature
