A recent meeting of the New England Local Section of SNAME was held in Newton, Mass., at which a paper entitled "Standard Waste-Heat Recovery Systems", authored by P. Schneider, was presented by his collaborator, Ernst H. Schaad.
Mr. Schneider is the head of the Diesel Installation Department of Sulzer Bros., Inc., Winterthur, Switzerland. Mr. Schaad works in this same department and is responsible for advanced projects.
In his presentation Mr. Schaad started by discussing the effects of the 1973 energy crisis on marine propulsion systems, and the efforts made by engine manufacturers toward contributing to an increased economy in ship operations.
Waste-heat recovery systems were then discussed in detail, including recovery of waste heat of the charge air coolers, and recovery of engine cooling water heat. The possible savings resulting from the use of these systems were then examined.
Alternatives and future solutions for economic sources for power were finally discussed.
The meeting was attended by over ninety members, student members and guests.
