ABSTRACT:
A steam injection system for use in a gas turbine engine having a turbine coupled to an air compressor for providing air to the turbine combustor. Steam generated by a boiler or the like is treated by removing moisture and particulates from the steam supply and steam is then injected by a line into the combustion chamber. A control unit is arranged to sequence a series of valves so as to purge the line each time an injection cycle is started or ended. The valves can also be sequenced during an emergency shut down to prevent steam from flowing back through the compressor.
