This paper presents an overall description of GE''s current LM series of aeroderivative gas turbines with power output ranging from 13 to 47 MW.

Due to the power needed to run the compressor, the energy conversion efficiency of a single-cycle gas turbine is from 20% to 35%, and even the most efficient design has an efficiency of up to 40%. A lot of heat remains in the exhaust gas, which has a temperature of up to 600°C as it exits the turbine.

HP steam is exhausted at vacuum conditions and is condensed against a cooling utility. Steam turbines typically rotate at 3,000–15,000 rpm. At that speed, water droplets can form and unbalance the turbine blades, causing severe mechanical damage. BPSTs can usually operate safely at up to 3% moisture ( i.e., a minimum steam quality of
