  • Control Of Steam Boilers And Waste-Gas Boilers (AREA)

Abstract

PURPOSE: To control the output of an electricity generator and the pressure of main steam well, by regulating the output of the electricity generator at the side of a boiler and the pressure of the main steam at the side of a turbine.
CONSTITUTION: The difference between the generator output signal of an a generator output transmitter 6 and the generated electricity quantity command of a central load dispatching office is applied to a proportional and integral processor 3 to produce a compensation signal. The compensation signal is applied to the generated electricity quantity command to produce a boiler command signal. The boiler command signal is used to regulate air, fuel and feed water to control the output of an electricity generator to be equal to the generated electricity quantity command. The difference between the main steam pressure signal of a main steam pressure transmitter 1 and a set value prepared by a function generator 5 on the basis of the main steam pressure signal and the generated electricity quantity command is applied to a proportional and integral processor 8 to move a turbine regulating valve 9 to control the pressure of main steam to be equal to a set level determined by the load. According to this constitution, the output of the electricity generator under the maximum boiler capacity can be obtained regardless of the speed of the fluctuation in the load and the control of the pressure of the main steam is improved.
