    摘要: A shaft sealing system and method are disclosed for a high or intermediate pressure turbine section having a rotating member including a shaft and a stationary member surrounding the rotating member and defining a steam flow path. The shaft sealing system comprises at least one seal disposed about each of a first end and a second end of the shaft; and a connection line for conducting steam from the first turbine section to a downstream portion of the turbine. The downstream portion of the turbine is one of a low pressure section and a condenser, and has a lower pressure than both of the first turbine section and ambient pressure conditions.

    摘要: A method and system for gas turbine emissions management through delivery of a diluent fluid stream (steam, CO2, N2 etc) into a gas turbine combustion system while the gas turbine is operating on a conventional fuel such as light distillate oil or natural gas. The diluent injection system delivers required diluent-to-fuel ratios over the emissions compliance operating range of the gas turbine. The method for diluent injection is coupling the injection system to a gas turbine compressor discharge purge system, such that the diluent fluid is mixed with compressor discharge air. The mixed compressor discharge purge air and diluent stream are injected into the gas turbine combustor through a non-fueled combustion fuel nozzle passage to achieve emissions guarantee compliance.
