| description | Liquid fueled flameless combustion is a new niche in the energy-engineering
department. The current trend on flameless combustion is mostly focused on gas fuel application due
to the ease of achieving and maintaining flameless mode in the combustion process. The main
purpose of this paper is to discuss the effects of evenly distributing tangential air inlets along the
length of the combustion chamber of a Direct Injection Liquid Fueled Swirl Flameless Combustor
(SFC) to the combustion characteristics in flameless mode. Ethyl alcohol or ethanol was used
throughout the whole experiment. Only four tangential air inlets were used in this experiment for
each configuration, whereas ethanol was directly injected axially. All 9 configurations were
strategically divided into three categories; a) single inlet location, b) dual inlet locations, and c) triple
inlet locations. The experiments were conducted at close to stoichiometry condition. The results
showed that, although flameless mode was successfully achieved and stabilized at every
configuration, it was also found that tangential air inlet configuration has a significant effect in the
optimization and behavior of liquid fueled flameless combustion. The highest peak temperature was
recorded by Configuration (G) at 800.45 oC, bur interestingly managed to produce the lowest value
for the emission of CO and NOx gases, which were at 134 ppm and 0 ppm respectively. Thus, it was
concluded that the best tangential air inlet configuration in this work was Configuration (G). |
