The outage time necessary for inspections and repair of faults and damages can be substantially reduced by rapid cooling of steam turbines. This Instruction Sheet describes various processes for cooling down steam turbines. The information contained herein is based on many years of experience as well as some new findings of  operators and manufacturers of steam turbines.
The Instruction Sheet was drawn up by a Working Group of the Working Panel "Turbine Operation" in the VGB  Technical Committee "Steam Turbine and Steam Turbine Operation".
