Abstract
Many continuous emission monitoring systems (CEMS) have been installed in Swedish heat and power generating plants over the last years. Several of these CEMS are used to monitor NO{sub x} emissions for the payment of environmental fees for NO{sub x} emissions. The NO{sub x} fees have to be paid at a fixed high rate during an eventual breakdown of the CEMS. This makes it economically interesting to keep the CEMS in good operating order, but should also create a need for backup equipment that can be used during periods with CEMS breakdown and overhaul. Such a back-up equipment would be used continuously only for short periods during which supervision and calibration could be frequent. On the market today several types of simpler instruments with electrochemical cells are available. The report presents the results from tests of 3 instruments of this type, in the price range 70-150 KSEK approx. All 3 instruments were equipped to measure O{sub 2}, NO, NO{sub 2}, CO and SO{sub 2}. Tests were carried out at the laboratory and at a bark- and oilfired boiler. The purpose of the tests was to check instrument performance compared to authority regulations and to get experience of the instruments function

None of the laboratory tests showed results that exceeded authority regulations. The performance tests at the boiler gave more mixed results. Some of the test results exceeded the regulations for one or other of the instruments, but no generally negative result for the measurement principle as such could be noted. The overall conclusion is that this type of instruments, properly used and maintained, can constitute a good back-up for CEMS in many plants. (2 refs., 20 figs., 5 tabs.).}
