This report deals with technical problems that will be taken place when the future marine steam turbine plant burns hydrogen gas as a fuel. As the steam turbine plant uses a Rankine Cycle with being an external combustion engine, there will be considered to exist the problems associated with utilization of hydrogen as a fuel in the boiler component. The combustion characteristics of hydrogen used in the marine boiler different from conventional fossil fuel are followings; 1) high diffusion coefficient in the air, 2) small ignition energy, 3) broad inflammable limit, 4) high combustion velocity, 5) high possibility of explosion, 6) non-luminous gas flame, 7) small radiant energy from flame, 8) high content of steam vapor in combustion gas, 8) no corrosion of high and low temperature ranges. Studies conducted here to investigate to solve the subjects are constructed as following topics. (1) An experimental study of hydrogen combustion in the small test boiler is performed to get overall absorption coefficient of thermal energy release in the furnace. (2) A conceptual design in a marine boiler for hydrogen combustion and a layout of machineries in the engine room for a hydrogen transport tanker are conducted and discussed. (3) Difficulties involved in the utilization of hydrogen to the marine steam turbine plant when the hydrogen energy system will be introduced in the future are discussed and found to be able to solve.
