Four way STAL-LAVAL steam turbine power for large tankers and container ships STAL-LAVAL has long pioneered the special advantages of steam turbine propulsion, its high reliability, low mainte-nance, space economy, ease of operation. Now we offer three variations of the CONVENTIONAL STEAM TURBINE design. LOWER PROPELLER RPM speed leads to higher efficiency? A reduction of propeller speeds from 110 to 80 rpm often results in increased propulsive efficiency of 7 to 11 % depending on ship size. THE REHEAT PRINCIPLE leads to additional economy? approximately 1% reduction in fuel rate. 32 Maritime Reporter/Engineering News
