ABSTRACT:
A method for the in-situ predetermination of the effects of NOx reduction systems on selected components. This determination can yield quick, inexpensive and accurate results for a number of characteristics, for example: catalyst longevity; efficiency with differing fuels, in differing locations, and at different temperatures; potential of catalyst poisoning in specific circumstances; ammonia slip considerations; SCR and SNCR interplay, as well as staged NOx reduction design criteria; pressure and blockage considerations; downstream effect on air preheater elements; and more. These determinations can be made in real, or accelerated time. Furthermore, the determinations can be made before any system modifications are made, or to assist in increasing the efficiency of existing systems, or even to assist in predictions of preventive maintenance and associated down time.
