METHOD FOR DETERMINING THE DESIGN CONDITIONS OF HEATER AND DEAERATOR IN A THERMOELECTRIC POWER PLANT

摘要

The present invention relates to a method for determining feedwater heater and degasser design conditions in a thermal power plant.;The present invention comprises the steps of receiving a pressure and enthalpy for each component by selecting the components in the thermal power plant to determine the design conditions, when switching to the design condition determination mode; And determining and outputting a design pressure and a design temperature of the selected component using pressure and enthalpy, in accordance with the design characteristics.;Therefore, the present invention, when determining the design conditions of the feed water heater and deaerator in a thermal power plant, only the pressure and enthalpy of the power plant components input based on the thermal balance of the thermal power plant for the optimal design of the component By automatically determining the pressure and temperature, it is possible to obtain design conditions such as design pressure and design temperature of a component for optimal design by simple data input, and to shorten the overall design time of the corresponding component, and supply water made of the same structure or material. Even if the system manager or designer changes for the heater and the deaerator, constant design conditions are always determined, which has the effect of designing a high quality thermal power plant.
