Symposium Energy Materials 2017: Energy and Environmental Issues in Materials Manufacturing and Processing
Presentation Title Fluoropolymer Coated Condensing Heat Exchangers for Low-grade Waste Heat Recovery

On-Site Speaker (Planned) Mehdi Mehdi
Abstract Scope Low-grade waste heat from industrial processes usually has temperatures lower than ~232°C, and thus has low thermal and economic value. However, it is abundant and its total work potential is huge. To effectively recover low-temperature waste heat, the exhaust streams usually need to be cooled to temperatures below the dew points to recover both the sensible and latent heats, which causes severe corrosion problems in the heat exchangers. In this research, a fluoropolymer-based composite coating was applied to heat exchangers made of common metals (e.g. stainless steel, aluminum, carbon steel, etc.) to protect the surfaces contacting the waste streams. Corrosion tests were conducted in 80% sulphuric acid at 85°C for more than 1500 hours and no corrosion was detected. The composite material has much higher thermal conductivity than virgin fluoropolymer, and can be continuously utilized at temperatures up to ~260°C. It also shows excellent adhesion strength to the substrate.
