Determination of correlation functions of the oxide scale growth and the temperature increase
In this paper, a method for estimating the scale growth of superheater and reheater tubes of boiler and generating the constant B which is correlating the scale growth and the increased tube metal temperature, for different operational conditions is reported. This method utilizes an empirical formul...
