In this study, effective use of exhaust heat as one of the way saving energy of vessels is described. Recent years, the depletion of fossil fuels, air pollution by exhaust gas has become a serious problem. Therefore, the technologies about fuel saving and effective use of energy are required. Vessels also use fossil fuel as an energy source. Large vessels generate steam in the exhaust gas economizer by using the exhaust heat of the main engine. This steam is used for heating fuel, heating the room and hot water supply in the vessel. But, recovery of exhaust heat of the main engine is not enough. If it is possible to generate electric power using the low-pressure steam, that can contribute to energy saving of vessels. Therefore, prototype steam engine for generation using low-pressure steam was developed. This new steam engine is use the grooved cam as a motion conversion mechanism. First, prototype steam engine is introduced for the principle and structure. Secondly, this steam engine is introduced for the configuration and design. Next, this engine is tested by low-pressure compressed-air and saturated steam. Finally, test result of the prototype steam engine is reported on this paper.
