  NOx Monitoring in Gas Turbines
  • A gas turbine is basically an engine. First, the compressor compresses air and converts it to high pressure air. Then, combustion takes place, and high pressure hot gas is produced. In the last stage, energy is extracted from high pressure hot gases, and for instance a rotor is driven at high speeds.
  • Control of combustion temperature plays an important role in running a gas turbine efficiently. If the combustion temperature increases, the NOx levels also increase, while the CO goes down. Reverse happens when the combustion temperature is brought down. A turbine therefore, has to be run at optimum temperature, to keep a control over NOx and CO levels.
  • A wear and tear of turbine parts is also indicated by an increase in NOx levels. Hence, it is very important to monitor exhaust gases coming out of a turbine.
  • O2, CO, and NOx are measured at the Gas Turbine exhaust. .
  • The testo 340 with sensors for CO, NO, NO2 is the perfect solution.
