Abstract
PURPOSE: To provide a steam temperature controller which prevents the temperature of steam from fluctuating due to disturbance, by performing the subtraction correction of a feed water flow rate command on the ground of the deviation of the detected value of heating flow rate from a command for the heating flow rate and the deviation of the detected value of heating temperature from a command for the heating temperature.
CONSTITUTION: The steam temperature is detected by a detector 4 and applied to a subtracter 6 through a steam temperature setting unit 20 and a steam temperature PI regulator 5. The difference between the heating flow rate instruction generated by a heating flow rate instruction function generator 10 and the signal from a heating flow rate detector is determined by a caluclator 14 and entered into a subtracter 15. The difference between the temperature command signal generated by a heating fluid temperature command function generator 17 and the signal from a heating fluid temperature detector 16 is determined by a calculator 18 and entered into a subtracter 19. Thus, the output instruction from an output instruction generator 3 is corrected by the subtracters 19, 6, 15 to control the flow rate through a regulating valve 9.
