Abstract
Experiments were performed on the central body rich-pilotlean

(RPL) burner of a Siemens Industrial Turbomachinary 4th

generation DLE combustor to observe the combustion changes

that may occur when using fuels other than natural gas. Measurements

were taken of temperatures at multiple points along

the RPL body while hydroxyl (OH) radical distribution extending

from the dump plane of the burner was imaged by planar

laser induced fluorescence (PLIF). The RPL burner was run using

four fuels; methane, a generic syngas (67.5% H2, 22.5% CO

and 10% CH4) and dilutions of these with nitrogen to a Wobbe

index of 15 MJ/m3. Each of the fuels was operated at... (More)

four fuels; methane, a generic syngas (67.5% H2, 22.5% CO

and 10% CH4) and dilutions of these with nitrogen to a Wobbe

index of 15 MJ/m3. Each of the fuels was operated at several

equivalence ratios ranging from f = 0.80 to f = 1.80, for combustion

pressures of 3, 6 and 9 bar. It was found that the flame

position in the RPL, determined from temperature measurement

at the thermocouple positions, was dependent on the fuel, equivalence

ratio and to a lesser extent pressure. A link was established

between the OH distribution in the post burner region and

RPL temperature profiles based on the expected flame behavior

inside the RPL. For all measurement points some combustion occurred

within the burner volume, indicated by thermocouples at

the burner exit. (Less)
