PURPOSE:To effectively use the energy of steam by-passed around a steam turbine, by storing the by-passed steam and thereafter supplying the steam to a machine in a plant. CONSTITUTION:When the load upon a steam turbine is not higher than a set level, valves 16, 19 in by-pass pipes 17, 18 are open so that by-passed steam is reserved in a storage unit 22. In rated operation, valves 26a-26c in feed pipes 25a-25c are sequentially opened so that the reserved steam is supplied in an almost saturated state to low-pressure feed water heaters 12a-12c and heats condensate. |
