Abstract
Temperature and species concentration measurements obtained by laser Raman spectroscopy are reported for a steady‐state, laminar, methane‐air flame impinging on a cooled metal wall. The concentration profiles for CH4, CO, and CO2 measured parallel to the wall at distances of 1500 (free flame) and 150 μm (near wall) are unexpectedly similar. This result is surprising in view of the much lower maximum temperature (870±50 K) measured at the near‐wall location compared with the free flame (2000±50 K). Rapid fuel oxidation would not be expected at such low temperatures.Keywords
