Startup analysis of an H sub(2)-O sub(2)-fired gas turbine cycle

A new thermodynamic cycle using artificial energy is now under investigation. The Japanese World Energy Network research program (WE-NET) is one of the artificial energy technology programs which will use hydrogen energy. One of the targets of the program is the development of a high-thermal-efficiency, emission-free power plant. The H sub(2)-O sub(2)-fired gas turbine is the key technology of the program and the advanced Rankine cycle is suggested as one of the most effective cycles. The advanced Rankine cycle is based on the direct steam expansion cycle. Mass and heat balance calculations were performed to determine the optimal operating point and the component design was carried out to develop the cycle. Further investigations necessary to realize the cycle include such topics as operational ability and cost performance. This paper considers operational ability, especially startup performance. In this analysis, the algorithm and process flow configuration for startup are developed. The investigation finds that the advanced Rankine cycle has good potential for practical use.
