Abstract
Coal remains to be considered as one of the future major energy sources. However, the formation of steam-side oxide scale as a result of the oxidation process during the steam power plant operation has been widely known to be a serious main root cause, leading to some risks/consequences. This paper presents a simple incremental method to determine the oxide scale growth in the ferritic alloy boiler (reheater and superheater) tubes for a given period of time making use of a classical heat flow formula and the correlation of the oxide scale thickness versus the Larson Miller Parameter (LMP). The ferritic alloy tubes have been used worldwide, especially in the supercritical steam power plants. The presented method may be used as a supplementary monitoring tool for estimating the growth of steam-side oxide scales in boiler tubes.
