EF 式ガスタービンのための高温型セラミック熱交換器の研究

抄録

There has been growing interest on renewable energy because of the recent environmental and energy problems. Among them, solar thermal and biomass can be applied to the existing gas turbine cycle as good options to solve current problems. In the EFGT (externally fired gas turbine) cycle, one of the key components is heat exchanger, and improving its heat resistance is an essential issue. This paper proposes the model of Spiral Heat Collector, which comprises of ceramic heat exchanger and combustor parts, and shows the result of the numerical analysis. Then we evaluate performance index such as heat transfer and temperature effectiveness.
