Application of Modern Heat Transfer and Fluid Flow Experience to the Design of Boilers for Automotive Steam Powerplants

Developments in boilers and other types of heat transfer equipment in recent years have improved our understanding of the heat transfer and fluid flow phenomena involved. These developments are reviewed, and their implications relative to the design of boilers for modern automotive steam powerplants are considered. A new approach to automotive boiler design, intended to exploit these new concepts, is suggested. This entails the use of a recirculating boiler with a regenerator, a combination that should reduce the size, weight, and cost of the boiler as well as increase the thermal efficiency of the powerplant. A design procedure is proposed.
