Evaluation of Sulfide Corrosion Conditions in Pulverized Coal Fired Thermal Power Plant Boilers

摘要：

Due to cutbacks in operational costs,many pulverized coal fired thermal power plant boilers have recently been operating under conditions of in-furnace reduction atmosphere enhancement.As a result,stronger in-furnace reduction atmospheres have led to sulfide corrosion.CRIEPI has conducted a study to clarify correlations between boiler operation conditions and sulfide corrosion,and to develop effective sulfide corrosion couritermeasures.This report therefore describes experimental and theoretical results of research into evaluation techniques for a sulfide corrosion environment,along with actual applied results of evaluation techniques for a sulfide corrosion environment using an in-furnace of an active boiler.
