Abstract
An apparatus for starting a turbine plant includes tubing or conduits for directing compressed air to the compressor stage of the turbine plant, whereby the turbine plant may be rotated to a speed sufficient for starting. Arranged in parallel with the compressed air tubing or conduits are additional conduits for conveying dry air to the turbine plant during rest or shutdown periods when the turbine plant is inoperative. A valving arrangement permits selective flow of compressed air through the apparatus for starting the turbine plant or of dry air for maintaining desired conditions within the turbine plant during rest or shutdown conditions.
