Ammonia (NH_3) contained in coal gasified fuel is converted to NO_x in the combustion process in gas turbine combustors. Low fuel NO_x combustion technology is very important. The present numerical computations are carried out for laminar jet diffusion combustion taking detailed chemical kinetics and multicomponent diffusion into consideration. Attention is focused on the effect of pressure on NO_x formation. By distinguishing the reaction paths of the fuel NO and thermal NO reaction processes, the interaction between fuel and thermal NO is clarified and the conversion rate of NH_3 to fuel NO can be computed directly. The result shows that high pressure induces an increase in thermal NO formation and a decrease in fuel NO formation and the conversion rate of NH_3 to fuel NO during combustion.
