Ceramic heat exchanger technology development
Abstract
Technology for pressurized, high temperature, ceramic tube heat exchangers was established by materials evaluation, design, and fabrication studies followed by rig tests. Candidate ceramic materials were surveyed for strength, environmental stability with coal ash, and other design properties. Design and fabrication studies of joining methods were responsible for selection of the chosen heat exchanger configuration. A full length, 28 tube, 4.56 m ceramic tube heat exchanger with a 11.43 cm diameter ceramic header is successfully tested with a 15050K (22500F) outlet temperature at 689 kPa (100 psi). Hot side gas temperature during this test was 16430K (25000F). The module operated for approximately 125 hours.
