。On the other hand, a steam pressure detector 5 detects the steam pressure at a representative point in a common steam reservoir to which the boilers 11 to 1n are connected, and the detected signal is input as a feedback signal to the steam pressure regulating means 6. Then, the actual steam pressure is compared with the desired steam pressure setting value, and an adjustment operation is performed so that the actual steam pressure matches the desired steam pressure, and the output signal of this steam pressure adjusting means is guided to the second adder 4, and Add to total steam flow signal.

。However, in the conventional load distribution control device described above, a deviation may occur from the generated steam flow rate command value due to differences in the dynamic characteristics and efficiency of the boilers 11 to 1n operating in parallel, and the It was difficult to follow accurately. In other words, a boiler with a quick response generates a large amount of steam in response to the command value of the generated steam flow rate, and a boiler with a slow response generates a small amount of steam in response to the command value in equilibrium.

A load distribution control device has been proposed which adjusts the amount of steam generated by each boiler by comparing it with the detected output of 2n and performing adjustment calculations, and guiding the output to each boiler 11 to 1n as a generated steam flow rate command signal.

The steam flow rate generated at 1n is detected by each of the steam flow rate detectors 21 to 2n, and these steam flow rate detectors 21
The output signals of ~2n, that is, the actual generated steam flow rate signals are added and synthesized by the first adder 3 and then input to the second adder 4. In addition, the detection signal of the steam pressure detector 5 that detects the representative point steam pressure for each of the boilers 11 to 1n is used as a feedback signal, and the actual steam pressure is compared with the desired steam pressure setting value so that the actual steam pressure matches the desired steam pressure. The output signal of the steam pressure adjustment means that performs adjustment calculations is also input to the second addition means 4, and this steam pressure adjustment signal and the total steam current signal are added. Thereafter, the output signal of the second adder 4 is input to the coefficient means 71 to 7n corresponding to each of the boilers 11 to 1n, and multiplied by the load distribution coefficients α1 to αn to become a generated steam flow rate command signal, which becomes a steam flow rate command signal. It is input to adjustment means 111-11n and correction means 121-12n. In the flow rate adjusting means 111 to 11n,
For example, proportional adjustment calculation is performed at regular intervals using the generated steam flow rate command signal as a target signal and the actual generated steam flow rate signal outputted from the steam flow rate detectors 21 to 2n as a feedback signal, and the output signal is used as the correction signal. Means 121

The generated steam flow rate command signal calculated in is subjected to feedback control based on the actual generated steam level, and is corrected so that the timely generated steam flow rate command value is equal to the actual steam generated amount. Therefore, even if a discrepancy occurs between the old steam flow command value and the actual steam flow rate due to differences in the dynamic characteristics and efficiency of each boiler 11 to 1n, this discrepancy is quickly corrected, and each boiler 11 to 1n Stable control is performed to follow the command value without vibration. As a result, each coefficient means 71

2n, the level change amount of the deviation output may be calculated by the level change amount calculation means 241 to 24n, and when this level change amount is large, the relays 231 to 23n may be driven. The control based on the amount and the control using the timers 22'j to 22n may be combined. Further, in the embodiment described above, a case has been shown in which the steam flow rate adjustment means 111 to 11n that operate discontinuously are used to perform the correction intermittently, but the correction may be performed continuously. However, in this case, there is a possibility that the control may become unstable due to a delay in the response of each boiler 11 to 1n. It goes without saying that various other modifications can be made without departing from the gist of the present invention.
