Abstract


Regenerative heater is an important device of modern thermal power plants to improve the economy , its run of good or bad has a direct impact on the entire unit . Difference from heater is an important factor to decide heater running state , the size of the reference value of the heat recovery system is very large . The heater overall heat transfer coefficient in the the solving end difference function relationship solving methods is particularly important . This article as a theoretical basis for the entire unit , through-flow part of the , and Condenser parameter reference value method , obtained under variable conditions end method for determining ; rated conditions , through theoretical analysis derived variable conditions heat transfer coefficient under rated conditions of heat transfer coefficient relations , solving the variable conditions of heat transfer coefficient is more concise and accurate , while improving end poor accuracy . This provides a theoretical basis for the operation of the power plant , has a certain significance .
