Abstract
12 In recent years a big effort has been made by gas turbine manufacturers in order to design industrial combustion apparata with high efficiency. Laser based diagnostic methods have become now a powerful tool for monitoring the performance of these devices. A portable high sensitive diode laser gas analyzer has been used to detect the unburned methane in the exhaust of a 213 kW combustor (General Electric DLE). The main features of the methane analyzer are a tunable diode laser operating at room temperature emitting radiation at 1.65 micrometers and a Chernin optical multipass cell. The gas analyzer is controlled by a computer program, which can supply real time concentration measurements. The latter characteristic coupled to its limited dimensions allow for in situ implementation of the spectroscopic tool.
