Ensuring the efficient operation of combined heat and power plants with the testo 350 flue gas analyzer.

When it comes to the commissioning of combined heat and power plants, long-term monitoring of their motors using an appropriate analyzer is particularly important. To do this, the fitter responsible must always keep an eye on the NOx and lambda values above all. This also applies to regular maintenance checks on the legal emission limit values – a task which involved using a lambda probe at 2G in the past. However, it was very imprecise and had to be replaced every year, which meant extra costs and workload.

In order to be able to develop, commission and maintain their combined heat and power plants in a more efficient way, 2G Energy AG decided on the testo 350 flue gas analyzer. It meets the highest demands in industrial emissions measurement: easy handling, accurate measuring technology and robust design are practical features which impress on a daily basis. Furthermore, it can be fitted with up to six gas sensors. Five of these are available as an option enabling a free choice between sensors for CO, NO, NO2, SO2, H2S, CxHy or CO2.

2G's 150 service engineers are each equipped with a testo 350 in order to carry out maintenance and breakdown service operations. However, the company's commissioning engineers, who connect 2G plants to the grid all over the world, also use the analyzer. For them, the analyzer's robust case, which also means it can be transported by plane without any problem, is one of the elements that has proved its worth. Furthermore, the research and development department uses the testo 350 for efficiency measurements. One of the most important functions of the testo 350 for 2G is dilution (measuring range extension). This gives the possibility of diluting the measurement gas to a ratio of 39:1, so as to be able to measure particularly high concentrations as well.
