Abstract

Experimental determination of the gas composition in full scale furnaces is important for the understanding of the kinetics of the gas phase reactions and the formation of different intermediates in the combustion process. Measuring the gas composition in the furnace area sets certain requirements on the sampling method. Challenges when measuring in the furnace area are e.g. high temperatures, particles in the flue gas and the complexity of the gas composition. A gas sampling probe for determining the flue gas composition in the furnace area of a recovery boiler was developed. The developed gas sampling probe is based on dilution of the gas sample in the probe tip with nitrogen, to quench the ongoing combustion reactions in the flue gas. To determine the dilution ratio a tracer gas, sulfur hexafluoride (SF6), was added to the dilution gas. The developed gas sampling probe was tested in a large recovery boiler and was connected to a Fourier Transform Infrared (FTIR) analyzer, two gas chromatographs (GC) and an oxygen analyzer.
