CRITICAL MATERIALS PROBLEMS IN COAL CONVERSION.

Research output: Contribution to conferencePaper

Abstract

The stability of engineering materials in coal conversion systems is reviewed with respect to effects of specific chemical species: carbon, sulfur, oxygen, hydrogen, chloride and other species. These chemical species operate both at low temperatures and high temperatures to accelerate the deterioration of engineering materials. These species participate both in general degradation as well as highly localized attack such as stress corrosion cracking, dusting, intergranular attack and break away reaction phenomena. In addition to the strictly chemical influences on the metals, the deterioration of metals in the coal conversion systems is accelerated by erosion and static and cyclic stresses which lead to stress corrosion cracking, hydrogen embrittlement and corrosion fatigue.
