Abstract
PURPOSE: To obtain appropriate amount of feed water by feed forward control and by issuing the signal in consideration of the change in main steam pressure and fluid pressure at the boiler inlet.
CONSTITUTION: The control system consists of two systems. The first one inputs into T-BFP operation governor 20 the deviation signal 15 between feed water flow demand signal 11 and feed water flow signal 12. The second inputs into said governor 20 the added value of 22 of signal 26 which is an output 40 of function generator 39 multiplied by a factor which put-puts zero when standard value 35 of main steam pressure is equal to or lower than pressure signal 36 and outputs the deviation signal when larger, and of signal 28 which is variable 33 of standard value 30 of fluid pressure at the boiler inlet and signal 31, multiplied by the factor. Signals 22 and 15 are received and are normally output 19 selectively, and only signal 22 of the second system will become the output signal 19 when FCB generating signal 17 is input. By this constitution, a proper feed water flow is obtained.
