PURPOSE:To utilize the high-temperature exhaust gas from a gas turbine as a main or auxiliary hat source at the time of starting or the like by controlling the quantity of transmitted heat so that the temperature of stored water detected by a temperature detector is equal to a set level, and by carrying the high- temperature exhaust gas from the gas turbine to a steam separator. CONSTITUTION:The high-temperature exhaust gas from a low-pressure gas turbine 1b is carried to a heat transmission device 13 through a heating air line 12 at the time of system starting or the like. In the heat transmission device 13, the exhaust gas is forcibly convected by a fan so as to be used as a heat source to heat stored water in a steam separator 6. The temperature of the stored water is found out by a temperature detector 14 and converted into an appropriate signal by a signal converter 15. The signal is entered as a stored water temperature signal into a controller 18 which compares the signal with a preset temperature signal to control the rotational frequency of a fan drive motor 17 by a fan motor rotational frequency regulator 16 depending on the difference between the compared signals, to equalize the temperature of the stored water to a set level. |
