Following an introductory discussion of the economics of waste heat recovery plant, the paper introduces the Seajoule cycle and discusses its underlying philosophy. In this system, the main engine exhaust gases are passed through a heat exchanger where approximately half their heat content is extracted to generate low-pressure steam. Precautions have been taken to ensure that those features which have given rise to service difficulties with exhaust gas boilers are eliminated. After requirements for accommodation and bunker heating have been met, the remaining steam is fed to a vertical spindle turbo-alternator, the design of which has been proven in a special development programme. Propulsion augmentation equipment has been designed as an integral part of the package to make the best use of any power which is surplus to the ship's internal requirements. A unique feature is the provision of an auxiliary propeller to provide "get-you-home" capability in the event of failure of the main propulsion machinery. A comparison of installation and operating costs of heating and generating plant is made for five ships to illustrate the advantages to be gained from the employment of various modes of waste heat recovery plant.
