The Normal Energy Balance Method and The Equivalent Heat Drop Methods

Using two new thermal parameters of extraction equivalent enthalpy and extraction efficiency,equivalent enthalpy drop method has features of convenience and flexibility for energy-saving potential of thermal system analysis.But the consistency with the result of traditional thermal balance method has been focus of people's attention.Relative research proved that the two methods have consistency on the main heating system.This paper discussed the mutual relations between these two methods,aiming at actual heating system including influences by auxiliary components of the use of gland steam,losses of steam and water,and feedwater enthalpy increase by pump.And proved the consistency of equivalent enthalpy drop method and the heat balance algorithm in theory by thermal equilibrium matrix equation.The calculation of the practical example validated this conclusion.
