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 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.
