MarAd Releases Two-Volume Report Prepared By DeLaval

The Maritime Administration has released a two-volume technical report which provides a comprehensive engineering and economic analysis of various improvements that can be applied to conventional two-heater steam turbine propulsion machinery systems to improve overall specific fuel consumption.

Cycle/machinery improvements are evaluated for both retrofitting into existing ships and for use in new construction. Stack coolers, fluid regenerative air heaters, condensate-cooled lube oil coolers, cascading bleeds, and two-row/' one-row turbines are all evaluated.

The report, entitled "Improvements in Non-Reheat Steam Propulsion Retrofit and New Construction," was prepared by the DeLaval Turbine Company, Trenton, N.J., under a contract with the Maritime Administration.

Copies of the report are available from the National Technical Information Service, 5285 Port Royal Road, S p r i n g f i e l d , Va.
