    Abstract: A method of minimizing nitrous oxide emissions in a gas turbine engine includes a step of monitoring pressure fluctuations within a gas turbine engine combustor and a step of adjusting fuel flow to the combustor if the pressure fluctuations therein exceed a preestablished threshold. The combustor can be operated at the lowest levels of nitrous oxide emissions since the onset of a combustor instability and/or blowout is identified early to allow for corrective action so that such undesirable events are prevented.

    Abstract: A method of combusting an endothermic fuel with staged rich/lean combustion includes transferring thermal energy from a heat source, such as the wall of a rich combustor, to an endothermic fuel decomposition catalyst to cool the heat source and heat the fuel and catalyst to a temperature sufficient to endothermically decompose an endothermic fuel. The catalyst is contacted with the fuel to cause the fuel to decompose into a reaction product stream. The reaction product stream is mixed with a first air stream to form a first fuel/air mixture having an equivalence ratio greater than 1 and the first fuel/air mixture is combusted in a rich combustion stage to produce a combustion product stream. The combustion product stream is mixed with a second air stream to form a second fuel/air mixture having an equivalence ratio less than 1 and the second fuel/air mixture is combusted in a lean combustion stage to produce an exhaust gas stream containing decreased amounts of NOx. The invention also includes a system for practicing the method.

    Abstract: A method of minimizing nitrous oxide emissions in a gas turbine engine includes a step of monitoring pressure fluctuations within a gas turbine engine combustor and a step of adjusting fuel flow to the combustor if the pressure fluctuations therein exceed a preestablished threshold. The combustor can be operated at the lowest levels of nitrous oxide emissions since the onset of a combustor instability and/or blowout is identified early to allow for corrective action so that such undesirable events are prevented.

    Abstract: Pressure fluctuations within a gas turbine engine combustor are monitored and the fuel flow to the combustor adjusted if the pressure fluctuations exceed a preestablished threshold. The combustor can be operated at the lowest levels of nitrous oxide emissions since the onset of a combustor instability and/or blowout may be identified early by this method to allow for corrective action so that such undesirable events are prevented.
