The new thermodynamic cycle using hydrogen energy is now under investigation by many engineers. The Japanese World Energy Network research program is also hydrogen technology development program. One of the target of the program is to develop the high thermal efficiency and emission free power plant. The H2-O2 fired gas turbine is the key technology of the program and the advanced RANKINE cycle is suggested as one of the most effective cycle.
The advanced RANKINE cycle is based on the direct steam expansion cycle. The performance calculation has been examined to find the optimal operating point. For the cycle development, further investigations of the component development, the operational ability, and the cost competitiveness are important. Among these investigations, this paper reports the operational ability, especially the start up performance.
In this analysis, the algorithm and flow line for start up is developed. And the investigation finds that the advanced RANKINE cycle has the good possibility for the practical use.
