Abstract
PURPOSE: To prevent a blow of a boiler's safety valve by automatically varying respective predetermined steam pressures of an automatic boiler combustion controller and a steam pressure controller on the basis of a turbine inlet steam valve opening signal or a turbine control lever signal.
CONSTITUTION: An automatic boiler combustion controller controls a fuel regulation valve 8 and a burning air control unit 9 on the basis of the signals of a boiler outlet pressure detector 1, a fuel flow detector 2 and a burning air flow detector 3. A turbine inlet steam valve opening or a turbine control lever signal 14 is output to a function generator 15 and herein added to the respective signals of steam pressure setters 4, 11 to provide results which are respectively used as predetermined values for the automatic boiler combustion controller and a steam pressure controller consisting of a steam damping valve 13 and a boiler outlet pressure detector 13. Thereby, the steam pressure predetermined value can be automatically regulated under various loads and there is no fear of a blow of a boiler's safety valve, which attains energy economization, prevention against the blow of the safety valve and saving of labour for operation.
