This paper presents a performance investigation of a number of available gas analyzers for ammonia monitoring in flue gases. The measurement systems included in the study were: MCS 100 (Perkin-Elmer), GASMET (Temet Instruments), OPSIS (OPSIS AB), GM 30 (Sick Opto-Electronic) and DOAS (Vattenfall Utveckling AB). The investigation focused on parameters such as the effects of interfering gases, comparisons between measured absolute concentrations of ammonia and obtained response times. The test program followed two stages: (1) measurements at a pilot scale oil burner for which the gas composition could be varied by injecting test gases, and (2) a comparison between the systems at a waste incinerator plant during various operating conditions. Results and experiences from the field testing and the measurements at the oil burner are presented.
