A hydrogen combustion turbine system has been proposed by Mitsubishi Heavy Industries, LTD. which is the Closed Circuit Cooled Topping Recuperation Cycle (CCCTR cycle) and is part of a Japanese government sponsored program WE-NET (“World Energy Network”). This cycle is composed of closed Brayton and Rankine cycles. The efficiency of this cycle is more than 60% HHV (Higher Heat Value) with a power capacity of 500MW. This cycle was selected as the most suitable for hydrogen combustion turbine used for industrial power plant by the Japanese government.A closed circuit steam cooling system has been proposed to cool vanes and blades of the high temperature turbine (HIT) which has inlet temperature of 1700°C and inlet pressure of 45bar.This paper presents the comparisons of the thermal efficiency and the feasibility of components between the CCCTR cycle and other cycles.Copyright

Mitsubishi Heavy Industries Ltd. have proposed the advanced hydrogen/oxygen combustion turbine system which is an inter-cooled topping recuperation cycle as part of a Japanese government sponsored program WE-NET (“World Energy Network”). The efficiency of this cycle reaches more than 60% (HHV), not (LHV), with a power capacity of 500MW. This cycle is formed by a compressor, turbines, a combustor and heat exchangers. The combustor bums hydrogen/oxygen to make high temperature (1700 °C) steam.

Marine gas turbines are prevailing on high speed vessel market lately based on its lightweight, compact and noiseless. However for real prevailing with diesel, fuel and efficiency are big obstacles. In case of fuel, environmental problem promote not to use the residual fuel. And it was verified that it was easy to get the distillate for gas turbine in Japan by TSL test. On the other hand the combined cycle is verified to be the best selection and much higher efficiency than diesel.
