Numerical analysis of a gas turbine combustor fueled by hydrogen in comparison with jet-A fuel

The combustion efficiency and the pressure drop values are increasing with an increase in the EAR values. But, the outlet temperature values of the combustion chamber, the CO2 emissions and unburned HC emissions are decreasing by increasing of the EAR values. Moreover, it is observed that the NOx emission values are increasing and then are decreasing with the EAR values. The combustion of hydrogen is seen as advantageous in terms of pressure drop, temperature values at the combustion chamber outlet and CO2 and unburned HC emissions. In addition, it can be seen that as advantageous in terms of the NOx emission values at low EAR values but as disadvantageous at high EAR values.
