Comparison on Algorithms Based on Equivalent Enthalpy Drop Method and Their Combined Application

The equivalent enthalpy drop method has been used widely for it is very brief and exact to analyze thermal systems. Different algorithms base on it have been developed for different problems by our scholars. Compared with the equivalent enthalpy drop method, these algorithms are more effective in dealing with the idiographic problems. The paper compares parts of these algorithms, improves the equivalent extraction steam method, and gives an example using the new method.
