Abstract:
An apparatus for the addition of nitrogen and moisture derived from low pressure steam to the fuel gas utilized to drive a gas turbine comprising:(a) a saturator tower adapted for the contacting of nitrogen gas with a hot water stream to form a mixture of water vapor and nitrogen gas; (b) conduit means for passing the mixture of water vapor and nitrogen gas to a heat exchanger unit where low pressure steam is used to produce a superheated mixture of water vapor and nitrogen gas; (c) conduit means for passing the superheated mixture to a chamber for mixing with feed gas to form a fuel gas mixture; (d) conduit means for passing the fuel gas mixture of fuel gas, nitrogen and water vapor mixture to a heat exchanger where low pressure steam is used to produce a superheated fuel gas mixture; (e) conduit means for passing the superheated fuel gas mixture to a gas turbine combustor.
