ABSTRACTWorld Energy NET Work( WE-NET) Program has been conducting by several organizations under contracts with New Energy and Indus-trial Technology Development (NEDO) as one of the biggest National Project since 1993.
Very Hot Side Heat Exchanger Development for Hydrogen Combustion Turbine System is one of the WE-NET Projects as a core devel-opment. This project has been managed by Japan Power Engineering and Inspection Cor-poration (JAPEIC).
As a feasible flow diagram of a hydrogen combustion turbine system had not been reached to the final conclusion until Fiscal year of 1996, this project had been focused on basic study of very hot side heat exchangers, and in Fiscal year of 1996, a topping regenerative closed cycle system were selected in this proj-ect. Then aiming to promote its R&D, these studies has been conducting by Toshiba Corpo-ration (Toshiba) and Mitsubishi Heavy Indus-tries Ltd. (MHI) under the contracts with JAPEIC.
This project will be terminated in Fiscal year of 1998. This report covers the results of basic studies on very hot side heat exchanger , one sample of conceptional design flow diagram of hydrogen combustion turbine generating sys-tem aimed at over 60% plant efficiency(HHV base) and present status of the studies of them for very high temperature and pressure condi-tions with 716C/5MPa and 593C/35MPa such as compact design study , engineering study, material selection and next step consideration for a commercialization.
