The degree of a vacuum control apparatus of power plant condenser

摘要

The present invention relates to a control device for controlling the vacuum degree of the power plant condenser sent to the air condenser by adjusting the pressure vacuum generated in the power plant condenser, more specifically, unlike the conventional method of maintaining the vacuum degree as low as possible using a manual control valve The present invention relates to a vacuum control device of a power plant condenser that improves power generation efficiency by automatically supplying an optimum pressure vacuum degree in consideration of various factors such as the output of the entire power plant, the temperature of seawater for cooling, and the outside temperature.;To this end, the present invention is a vacuum degree of the power plant condenser provided with a control valve (4a) is installed in the pipe (3) connecting between the condenser (1) and the air condenser (2) to adjust the degree of vacuum of the condenser (1) In the regulating device, in order to improve the accuracy of the vacuum degree adjustment, a small capacity vacuum degree precision auxiliary control valve 4b disposed in parallel with the large capacity vacuum degree control valve 4a is provided, and this control valve 4a and the auxiliary control valve are provided. (4b) is controlled together with the condenser vacuum control unit 5, wherein the condenser vacuum control unit 5 and the control valve (4a) which is installed in parallel by the output variable in consideration of the input to the various input variables and The opening state of the auxiliary control valves 4b is adapted to be adjusted.
