Determination of the Residence Time Distribution of a Combustion Air in a Recovery Boiler by Helium Injection and Concentration ...", 1998 International Chemical Recovery Conference Proceedings

The residence time distribution (RTD) of a chemical reactor is an important parameter being closely related to its mixing and combustion behaviour. By helium injection in the combustion air and measurement of the resulting helium concentration, the RTD of the recovery boiler can be determined and the mixing characterised. This allows different operating strategies to be compared with respect to their mixing properties. Two applications of the method are presented: investigation of rotational firing in a Swedish recovery boiler and a comparison between RTD’s computed with a CFD 1-model and measured values.
