Brief information is given on the MST-21 geared steam-turbine plant, which is now available from General Electric Company (of USA) and its associates and is designed to compete with the marine Diesel engine in the 9,000-19,000 shp range. It has an all-purpose fuel rate below 224 g/shp-hr, and a number of options, including reheat, are available which can improve this figure by as much as 19%. The plant can be operated without special crew skills. Bridge control is standard. The MST-21 has a cross-compound configuration, and is constructed in modular form. Standard (non-reheat) initial acciditions are 60 atm and 510 deg C, with 0.52 atm vacuum. There are four stages of feedwater heating, dual economisers, a steam/air heater, and cascaded bled-steam extractions. Though the plant is designed for single-screw ships with two boilers, the options include twin-screw and "one-and-a-half" boiler arrangements. The article includes fuel-consumption curves and a basic cycle diagram. Order from: BSRA as No. 47,167.
