Abstract
The paper defined the heat transfer characteristic coefficient (HTCC) of condense regenerate heater, and obtained the relationship between HTCC, and feedwater flow and power outlet, and then present the model of condense regenerate heater under off-design conditions based on the characteristics coefficient; the model is used for the calculation of outlet temperature and heater temperature difference. The parameters of the model needed are the data on the base operation rather than the heater structure and complicate calculation of heat transfer coefficient; the heater outlet water temperature can be calculated by the steam pressure and turbine power outlet. The simplicity and good accuracy of model are proved by the regenerate heater calculation of 330 MW unit under off-design conditions, which shows the potential value for engineering application.
