High-temperature heat exchangers in indirectly fired combined cycle (IFCC) systems: materials management and performance improvement

J.P. Hurley,     University of North Dakota Energy & Environmental Research Center,USA

Abstract:

In order to increase the efficiency of coal-fired power production, ultrasupercritical pulverized coal-fired boilers, indirectly fired combined cycle (IFCC) systems, and integrated gasification combined cycle systems are being investigated. Each type of system benefits from higher working fluid temperatures, which means higher-temperature materials are required for heat exchangers and turbines. In this chapter, a brief introduction to these technologies is provided, followed by a detailed discussion on the material, ...
