COAL FIRED STEAM PROPULSION FOR SHORT SEA RO/RO SHIPS

The types of Ro-Ro vessels plying the short-sea routes have been developed with extremely compact machinery spaces below their main vehicle deck and with very restricted head room. Therefore very compact coalburning machinery is required, which can fully match current medium-speed diesel engines for performance, spacial and operating convenience. The author proposes a compact steam power plant suitable for fitting into such vessels. By application of existing diesel engine technology, this reciprocating steam engine is built into an existing diesel engine crankcase. The two-stage compound engine uses an exhaust turbine to drive a steam compressor between the high-pressure and low-pressure cylinders, an arrangement which enables very high specific powers to be obtained with modest steam conditions of 25 atmos. and 530 deg. C and with an indicated thermal efficiency greater than 30%.
