Abstract

Chemically recuperated gas turbine (CRGT) is an advanced cycle, which recovers exhaust heat by endothermic reaction converting fuel into hydrogen-rich gas. CRGT can improve the generating efficiency of the simple cycle GT more effectivly than the stream injected GT cycle does. In our 1st report, we made clear required specifications of the reformer in the CRGT system with natural gas steam reforming and designed a reformer consisted of tube bank by numerical analysis considering mass and heat transportation and chemical reactions. On the next stage, we examined the designed reformer experimentally using a test module. We also examined combustivility and emissions of the low-BTU gas containing much steam in the combustion test. It was comfirmed that the reformer design was valid and heat recovery was evaluated accurately. Also, combustivility of the reforming gas was apploximately steady and the NOx emission was under 10 ppm.
