M&C has developed a special sampling technique for continuous sampling of waste gas in DENOX plants (SCR) where NH3 is added to the flue gas in order to reduce the NOX content. This new sampling technique has also proved to be suitable for processes with very high pollutant concentrations. In these applications, the measurement of NOX, SO2 and O2 concentrations is a major problem. With temperatures of < 300 °C, ammonium salts are produced due to the chemical reaction of NH3 and SO2/SO3 in the flue gas. This salification is blocking filters and sample lines in a short period of time. The special M&C gas sample probe SP2000-H320/S represents a good solution for these problems.
