摘要：

After more than 10 000 operating hours, the experience can be summarized as follows: The devices for NH4OH supply had to be improved. It seems to be advisable to monitor the reduction agent consequently. Comprehensive countermeasures had to be taken in order to solve catalyst problems (fly ash deposits, erosion). The gaseous NH3 slip was monitored by observing the NH3 content in the fly ash. The results achieved so far are plausible. The future development will be of interest, particularly with increased NH3 slip.
