Dynamic analysis of a flameless combustion model combustor

Flameless combustion is a new technology with the following advantages: 1) Ultra-low emissions of both NO X and CO; 2) fuel flexibility, from liquid fuels, natural gas to hydrogen-rich syngas; 3) lower possibility of flashback and thermoacoustic oscillations. In this paper, we focus on the dynamic characteristics of a flameless model combustor. Experimental results show that flameless combustion can lower emissions while maintaining combustion stability. However, combining a pilot flame with flameless combustion may excite thermoacoustic instability.
