Abstract

An improved closed loop Brayton cycle 100 for a power plant is provided that includes a heater 110, at least one turbine 120, a recuperator 150, at least one cooler 160, at least one compressor 170, a bypass line 180 and a flap valve arrangement 190 in a closed circuit in which working fluid is circulated to produce electricity via a generator 132. Depending upon the requirement, such as, in case of gird load disconnection, speed of a shaft-line to which the turbine 120, the compressor 170 and the generator 132 are configured is also required to be reduced without any impact on the pressure drop in the cycle. For that the non-tight flap valve arrangement 190 is configured on each conduit 140 between the heater 110 and the at least one turbine 120 in a closest possible proximity to each turbine inlet 122.
