Measurement of the Equivalence Ratio in an Atmospheric Gasifier Using Laser Induced Breakdown Spectroscopy

Peter Kutne; Marcel Ebenhoch; Wolfgang Meier; Sabine Fleck; Christian Hotz

Laser induced breakdown spectroscopy was used to measure the local equivalence ratio in an atmospheric gasifier operated with a mixture of ethylene glycol and char particles as model fuel.

Development of an Infrared Absorption Spectrometer for Temperature and Species Concentration Measurements in a Gasifier

Patrick Nau; Peter Kutne; Wolfgang Meier; Christian Hotz; Sabine Fleck

An absorption spectrometer utilizing a tunable distributed feedback diode laser at 2.3µm and an interband cascade laser at 3.1µm has been developed to measure temperature and concentrations of CO, CH4, C2H2 and H2O under gasification conditions. The setup has been tested and then applied for measurements at an atmospheric entrained flow gasifier.
