Experimental Study of Effects of Coflow Air and Partial Premixing on Liquid Petroleum Gas Flames

Abstract EN

Investigation of the influence of coflow and partial air premixing on liquid petroleum gas (LPG) flames in a lab-scale co-flow burner is presented.

Primary air is supplied along with LPG in the inner core, and secondary air is supplied through the annulus region of the burner.

Digital images are analyzed to study the flame shape, color, height, radius, and qualitative laminar flame speed.

Concentrations of product gases and emission species are measured using a digital gas analyzer.

Results indicate that in a dual air stream configuration, the partial premixing is optimum at % primary air value of around 45%.
