<p><P>PROBLEM TO BE SOLVED: To reduce thermal fatigue damage of a member that composes a power plant by suppressing the temperature fluctuation of steam to be small even when the insolation from the sun greatly varies, and to stabilize boiler control and turbine control by reducing control interference between control valves. <P>SOLUTION: The power plant includes a feed-water heater utilizing steam heat and a feed-water heater utilizing solar heat. In addition, the plant includes a first water pathway for running water toward an inlet of the feed-water heater utilizing steam heat, a second water pathway for running water discharged from an outlet of the feed-water heater utilizing steam heat, and a third water pathway for running water from the first water pathway to the second water pathway by bypassing the feed-water heater utilizing steam heat. In addition, the plant includes a thermometer for measuring the temperature of water flowing in the second or third water pathway, and a controller for controlling a distribution valve on the first water pathway and a distribution valve on the third water pathway based on the temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
