Estimated Emissions vs Gas Turbine Load

   Note that Mode 1 will commence immediately after first fire. Mode 2 will be nearly transparent before Mode 3 where we want to be during a start. By keeping the reference temperature fairly close to to the 2000° Mode 4 transfer temperature (without going over) we will make the least emissions for the turbine start while preheating the IP section for performance heaters and the HRSG for ammonia injection.

Compressor Inlet conditions:
59° F
60% Relative Humidity
Atmospheric Pressure 14.7 psia

Inlet / Exhaust = 3.5 / 5.5 inH2O and Fuel = 100% Methane

  1. Mode 1
  2. Mode 3, intiates transfer @ 1630° TTRF, transfers back into Mode 1 @ 1570° TTRF
  3. Mode 4, intiates transfer @ 2000° TTRF, transfers back into Mode 3 @ 1940° TTRF
  4. Mode 4
  5. Mode 6, intiates transfer @ 2280° TTRF, transfers back into Mode 4 @ 2230° TTRF
  6. Mode 6Q, Baseload TTRF approximately 2425°
