Abstract

PURPOSE:To enable a plurality of exhaust-gas boilers to be sequentially cold started and stopped safely and securely by causing a turbine bypass control system and a boiler stop valve control system to cooperate with each other. CONSTITUTION:When applying to a plant wherein steams from three boilers 1 are fed to one turbine 4, a control device is provided which comprises a pressure a pressure controller 9 for individually controlling each turbine bypass valve 11 and a common pressure controller 13, and controls the valve 11 by an output from a high-signal selector 10 which selects the higher signal of the outputs from the controllers 9, 13. Also provided is a control device which controls a boiler stop valve 2 by either of the outputs from high-speed and low-speed on- off controllers 25, 26. When starting the plant, the boiler stop valve 2 is closed, the first boiler 1 is controlled to attain the lowest pressure, and when additional gas feed conditions for the boiler 1 are satisfied, the first and second turbine bypass valves 11 are controlled.
