Steam turbine with reheat#
Block appearance in REPEAT VISION#
Steam turbine with reheat – is an improved steam turbine in which steam that has already passed through the high-pressure cylinder (HPC) is reheated before entering the low pressure cylinder (LPC). This process increases the efficiency of the turbine by using additional energy and improves its effectiveness.
