A novel laboratory-scale test was developed to simulate the individual corrosive effects of the heavy metal chlorides ZnCl2 and PbCl2 during high-temperature corrosion that occurs during the burning of certain fossil fiels and municipal waste. The test is a modification of the Dean test, which is often used in the study of hot-salt corrosion. Using ZnCI2 as the corrosive compound, a sample temperature of 950- 1000°F (51O-54O°C), and a N2- 14vol% CO2-3.6 O2 -0.25 SO2 inlet gas
atmosphere, corrosion rates similar to those obtained from a field study have been produced. Moreover, the measured corrosion rates were found to be inversely related to the (Ni + Mo + Cr) content in the alloys, and of the eleven different alloys studied, two C-type alloys and the 625 alloy performed the best.
