Ceramic heat pipe waste heat recovery, Phase 1

This report describes design simplifications and mass production concepts that can achieve a heat pipe cost of $448 each. A ceramic heat pipe recuperator design is presented which addresses fouling, cleaning, sealing and maintainability. Overall dimensions including ducts, flanges and insulation are 16 x 5 1/2 x 6 1/2 feet. The weight is 12.5 tons. The simple payback for the system is 0.73 year. A plan for Phase 2 work is presented, which addresses verification of the concepts developed in the study.
