Experiments have been conducted using liquefied petroleum gas (LPG) as fuel and O2/CO2 mixture as oxidizer in a horizontally-fired swirl stabilized co-axial, 15 kW burner. Visual observations of the flame as well as temperature profiles across the flame have been carried out for different oxidant mixture compositions and two different swirl ratios. Comparative measurements have also been made with air as the oxidizer. Results from these experiments show that stable combustion is possible and that, from the point of view of temperature profiles, oxy-LPG flames are equivalent to conventional air flames when the oxygen concentration is 34% by volume in the oxidizer. Increase in swirl velocity results in stable and symmetric flames. The oxyfuel flame is typically less bright and more bluish than its normal air counterpart. These results will be useful in retrofitting existing combustion systems for operation under oxyfuel combustion mode. © 2009 Combustion Institute. All rights reserved.
