The Determining Method Of The Power Unit Under Different Loads

Regenerative heater is the important equipment that improve the economy of the modern power plant ,It has a direct impact on the whole unit . temperature difference decides the running state of the heater ,It has a important impact on the kinds of standard number. The function of the temperature difference is very important in the course of solution of the heat transfer coefficient. This thesis is based on the whole unit with the method of parameters about flow pass and condenser ,and gained the standard number of the temperature difference, Through theoretical analysis gained the relation of heat transfer coefficient between the variable condition and rated operating condition, It make the heat transfer coefficient more concise and accurate. The model supplies the base to the power plant and is useful to direct the optimizing operation for power plant.
