twenty and ninety minutes prior to fuel gas admission to the fuel saturator 101 as the power plant starts up the water in conduits 136 and 110 heats up and the saturator pressure increases tracking the saturation pressure of the hot water entering the spray nozzles adjacent the top of fuel saturator 101 minus a small portion that flashes to steam the is water falls to the bottom of the fuel saturator 101 for recirculation to the saturation water heater 106 via pump 108 water flow to the saturator 101 in conduit 136 is controlled to its minimum value e g approximately 35 rated flow and water flow in conduit 110 is controlled to maintain the saturator 101 sump water level fuel admission to the saturator 101 begins at a predetermined load e g a 30 load particularly dry fuel gas flow in conduit 109 to the fuel gas saturator 101 is ramped from zero flow to full flow corresponding to an approximate 35 plant load over a time period approximately one minute by adjusting three way valve 148 alternatively two two way valves may replace the three way valve 148 during the first few seconds of admission of fuel in conduit 109 to the saturator 101 the saturator 101 pressurizes from approximately 85 lbs in 2 gauge to the fuel supply pressure when.
