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