Abstract

Coal-gasified fuel contains ammonia in a hot gas cleaning system in integrated coal gasification combined cycle (IGCC) power generation systems. Ammonia is converted to nitrogen oxides in the combustion process of a gas turbine. Research data on the NO_x formation mechanism in fuel is insufficient, and there still remains a wide unexplored domain. The present research aims at obtaining more fundamental knowledge by means of elementary reaction kinetics. We have obtained a very significant result by comparing the kinetics calculations with combustion experiments. The result is that fuel NO_x formation characteristics is affected considerably by the conditions of secondary-air mixing and the concentration change of methane in fuel.
