As energy consumption is rapidly increasing in the commercial sector in Japan, the market potential for a micro-gas turbine is expected to grow significantly if thermal efficiency is improved further. One way of improving thermal efficiency is to introduce a steam injection system that uses steam from the heat recovery steam generator. We have recently carried out several tests using a micro-gas turbine (Capstone C60). Test results show that this new device utilizing steam injection can improve some key performance parameters for output, thermal efficiency and emissions. The stable operation of the micro-gas turbine with steam injection was confirmed under various operating conditions. On the basis of the above findings, we hereby propose the use of a micro-gas-turbine-based cogeneration package with steam injection driven by a heat recovery steam generator (HRSG) with supplementary firing.
