| This study was a combined experimental and theoretical effort to determine (1) why increasing the pressure on a combustion chamber decreases the effluent NO concentration, and (2) which of four simple injector designs will yield the lowest NO and TFN during coal gasification. The experiments were performed in a laboratory scale entrained-coal gasifier with Utah bituminous coal. Samples were collected with a water quenched probe and analyzed for gaseous nitrogen species concentrations (N... |
