CH4/NH3 Flame Structure and Extinction Limit under Flame–Flame Interactions [PDF]
ACS OmegaAmmonia is considered to play an important role in replacing traditional fossil fuels in future energy systems. In the experimental study, CH4/NH3 flame was lit by applying a double-nozzle burner to gain insight into the structure, and the laminar diffusion flame structure, CH*/OH* intensity maximum, and flame size were analyzed by an ICCD camera.
