ABSTRACT:
Improvements in or relating to a reheating steam plant comprising a main steam line connecting a heater to a higher pressure turbine through regulating valves, and a reheated steam line connecting the higher pressure turbine to an intermediate pressure turbine through a reheater, a reheating stop valve and an intermediate stop valve. The improvements consist in the provision of a branch line branching off from the main steam line at a point disposed on the up-stream side of the regulating valves and connected to the reheated steam line at a point interposed between the intermediate stop valve and the intermediate pressure turbine, an adjusting valve mounted in the branching line, and a control for the adjusting valve. The adjusting valve is adapted to be opened when the turbine is under an overload so as to introduce to the intermediate pressure turbine a portion of the steam supplied from the heater.
