摘要： PROBLEM TO BE SOLVED: To provide a reduced-pressure vapor heating device in which fluid is surely supplied into superheated vapor to produce vapor of saturation temperature by preventing a foreign matter from being stuck and accumulated in the bottleneck part of a fluid supplying pipeline for changing superheated vapor into vapor of saturation temperature. SOLUTION: A gas-liquid separator 4 is fitted to a vapor supplying pipe 3. A valve means 23 capable of regulating opening is provided in the lower part of the gas-liquid separator 4. A combination pump 2 is connected in the lower part of the jacket part 11 of a reactor 1. A part of circulating fluid of the combination pump 2 is injected into the vapor supplying pipe 3 from a fluid supplying pipe 6. superheated vapor in the vapor supplying pipe 3 is desuperheated to vapor of saturation temperature by the supplied circulating fluid.

摘要： PURPOSE:To improve stability in steam turbine output and utilizing efficiency of energy by controlling the fuel supply adjusting means of a gas turbine by a controller based on a current steam amount and a current steam temperature in a steam supply pipeline. CONSTITUTION:A current steam amount and a current steam temperature in a steam supply pipeline are detected by a gas flow meter 112a and a thermometer 112b. Base on the current steam amount and the current steam temperature obtained, the fuel valve 306 of a gas turbine 301 is controlled by a controller 400. By the control of the fuel valve 306, the amount and the temperature of waste gas from the gas turbine to be supplied into the second steam superheater 111 are controlled. By the control of the amount and the temperature of the waste gas, the temperature of superheated steam to be supplied into the steam turbines 201, 202 is controlled to an appropriate level. It is thus possible to stabilize steam turbine output and improve utilizing efficiency of energy.
