説明
A regression analysis was conducted on corrosion rate of alloys tested in three typical domestic waste-to-energy plants. In this analysis, corrosion rate was assumed to follow parabolic or linear law and the rate constants were determined as a function of five independent variables, i.e., gas temperature, metal temperature, HCl concentration in the flue gas, Cl concentration in the ash deposit and the summation of Cr, Ni and Mo content in the alloys. The regression analysis of the predicted and observed corrosion rate constants showed an approximate 1:1 relationship for both linear and parabolic rate law with a correlation coefficient of 0.8. However, on the basis of comparison between the calculated and observed values in the pilot plant, the regression equation was modified. As a result, simple mathematical equations were derived, which are capable of predicting the corrosion rate of superheater tubes used in waste-to-energy plants.
