✦ Synopsis

A new NO abatement strategy proposes the use of the Ljungstroem air heater of the power plant as a chemical reactor, covering the air heater elements with a catalyst. A simple model has been developed to predict the performance of such a catalyst air heater. The model calculations are based on kinetic data obtained by laboratory scale experiments. The comparison of the calculated results with preliminary experimental data of a full-scale installed catalyst air heater proves the validity of the approach chosen. The catalyst air heater provides substantial NO reduction potential without requiring major modifications of existing power plant equipment.
