ABSTRACT
Legislative restrictions on pollutant emissions have motivated the combustion
community to seek new low-emission combustion techniques that are practical
industrial energy sources. However, to meet the needs in most industrial applica-
tions, a combustion source needs to be able to maintain low-emission output over
a range of heat release rates, occupy minimal volume, and have low operating
costs per unit energy produced. One would like to maximize the turn-down
ratio, volumetric heat release, and overall thermal eÆciency while minimizing
NO
x
, CO, and hydrocarbon emission levels. The ultra-low NO
x
emission per-
quirements have been discussed [1]. This paper focuses on turbulent ame speed
control to achieve reasonable turn-down ratios and volumetric heat release rates
while maintaining low NO
x
output.
