Gas turbine combustion system with controller

A burner system for clean combustion in gas turbines, comprising:

• an air manifold having an air inlet for receiving pressurized air;
• a combustor including a first shell surrounding a plurality of air tubes, wherein each air tube is connected to the air manifold, wherein the combustor is configured to burn a mixture of fuel, carbon dioxide (CO2) and oxygen (O2), wherein burning the mixture heats the pressurized air in the air tubes, the combustor further including a combustion outlet port, at least one igniter and at least one thermocouple;
• a headend connected to the combustor, the headend including a second shell surrounding a plurality of ceramic ion transfer membrane (ITM) tubes equally spaced longitudinally within the headend, wherein each air tube is further connected to an air space in the headend between the plurality of ITM tubes, the headend further including a first oxygen depleted air outlet;
• a preheating unit connected to the headend, the preheating unit having a third shell surrounding a heat exchange tube, a fuel port, a recirculated CO2 inlet port, an oxygen depleted air inlet and a second oxygen depleted air outlet;
• a thermally insulated pipe connected between the first oxygen depleted air outlet and the oxygen depleted air inlet;
• wherein the preheating unit receives fuel and recirculated CO2 from the fuel port and recirculated CO2 port respectively, wherein the fuel and recycled CO2 are preheated in the preheating unit, enter the ITM tubes, mix homogeneously with oxygen, burn as flamelets, and generate combustion products in the combustor, wherein the combustion products exit the combustor at the combustion outlet port,
• wherein the burner system further comprises:
• a computer system operatively connected to the air inlet, the first oxygen depleted air outlet, the at least one igniter, the at least one thermocouple, the second depleted air outlet, the fuel port and the recirculated CO2 port;
• wherein the air inlet, the first oxygen depleted air outlet, the second depleted air outlet, the fuel port and the recirculated CO2 port are computer controlled valves,
• wherein the at least one thermocouple senses the temperature of the preheated fuel, oxygen and recirculated CO2 and generates a signal to the computer system when the temperature is above a threshold;
• and
• wherein the computer system actuates each computer controlled valve to open the air inlet, the first oxygen depleted air outlet, the second depleted air outlet, the fuel port and the recirculated CO2 port upon receiving the signal.
