The main combustible gas components of the coal-derived gas fuel are CO and H2. Moreover, a small amount of NH3 and CH4 will be contained. NH3 contained in coal gas fuel will be converted to NOx in the gas turbine combustion process. This paper describes the study of the influence of the coal gas fuel properties such as CH4 on NOx formation from NH3, using experimental study by a laboratory-scale combustor and study of the reaction kinetics. As a result, a small amount of CH4in coal gas fuel was found to strongly influence NOx formation from NH3 in coal gas fuel.
