Abstract
Hydrocarbon-ammonia combustion is a potential phase-in of CO_2 reduction for large scale energy systems. In this study, chemiluminescence spectrum of flame, laminar burning velocity and exhaust gas of methane/ammonia/air premixed flames were investigated varying with ammonia concentration in fuel. NH_2 α band spectrum was observed and flames became orange with the increase in the amount of ammonia in fuel. The laminar burning velocity decreased with the increase in ammonia in fuel. CO concentration in burned gas decreased with the increase in ammonia in fuel. NO concentration rapidly increased when ammonia ratio increased from 0 % to 5 %, then NO concentration gradually changes when ammonia ratio increased furthermore.
