Abstract
PURPOSE:To automate starting operation of the condenser and achieve saving of manpower by disposing temperature detectors for various parts of the condenser, detector low value selector, low value detecting monitor, change rate limitor, etc. and providing a temperature control circuit. CONSTITUTION:In controlling steam valves 11 to the condenser, the temperatures obtained with temperature elements 23A thru 23D are inputted to a high input selector 31 and a low input selector 32. The output of the selector 32 is supervised with a monitor 33A. When it is below a fixed temperature, a changeover device 41 is so changed over that a steam valve 11 is controlled by the output signal of a change rate limitor 42. An automatic operation start command device 43 is inputted and the starting operation is accomplished by the above operation. The manual operation of the valve 11 is accomplished by changing a changeover device 47 to the manual mode, and abrupt operation of manual adjustment is prevented by the opening signal immediate before the changing over stored by an analog memory 44B. Since conventional steam flow constant control is made temperature constant control in the condenser, the responsiveness of the operation is improved.
