The purpose of this paper is to investigate the efficiency of different waste heat boiler arrangements for the main Diesel engine types, taking into consideration the influence of the more important design parameters such as live steam condition, condenser pressure, heating steam rate, feed-water temperature and engine loading on the electrical power produced. A thermodynamic comparison is made of four arrangements in general use(1) Exhaust-gas boiler without economizer; (2) Exhaust-gas boiler with economizer cooled by the feed-water flow; (3) Exhaust-gas boiler with economizer cooled by the recirculating flow; and (4) Exhaust-gas boiler with integrated economizer. An investigation has also been made of the efficiency of a turbo-generator comprising a reaction type condensing turbine with nozzle group control and thermal-elastic supported guide-blade carrier. The results of both investigations are presented in a series of design graphs to allow quick and reliable determination of the best waste heat boiler arrangement for the particular electrical energy requirements of the ship.
