Abstract- This paper discusses the development of a new carbon composite conductive material for use in wet electrostatic precipitators (WESPs). The objective was to develop a low cost alternative exhibiting improved properties compared to stainless steels and lead. After laboratory evaluation, field trials were undertaken using commercial-grade WESP tubes at two industrial sites. The material was further improved to increase arc resistance, while maintaining corrosion resistance and conductive properties. This new material, found to have better arc resistance than SS304L stainless steel, was used to manufacture a tube bundle and installed in a pilot WESP system.
