NOx sensors are commonly used in gas turbines to monitor and control nitrogen oxide emissions, which can contribute to pollution and environmental damage.
In gas turbines, NOx sensors are typically installed in the combustion chamber, exhaust ducting, or exhaust stack to continuously measure the levels of NOx emissions in the exhaust gas. The data collected by the NOx sensors is then used by the control system to adjust the combustion process and minimize NOx emissions.
Some of the major gas turbine manufacturers such as General Electric, Siemens, and Mitsubishi Heavy Industries use NOx sensors in their gas turbine designs to meet environmental regulations and improve performance. The specific part numbers for NOx sensors used in gas turbines can vary depending on the manufacturer, model, and application of the gas turbine.
Overall, NOx sensors play an important role in improving the environmental performance of gas turbines and helping to reduce their impact on the environment.
Gas turbine generators are an efficient and cost-effective solution for smaller power sources. They are flexible, simple, and come in packages that range in capacity from 20MW to over 1000MW. The gas turbine engine is reliable and has been proven to be a successful technology for almost any location. However, regulating agencies are reducing emissions standards to limit the release of pollutants into the atmosphere, and to meet these stricter standards, manufacturers are developing systems that can reduce the emission of pollutants, such as NOx.
NOx is produced as a result of fuel combustion in air and any nitrogen component in the fuel, making it the primary pollutant generated by standard gas turbines. Water injection systems have been developed to directly inject water vapor into the gas turbine combustor to reduce NOx emissions. Water injection works by reducing flame temperature, which reduces NOx emissions.
Demineralized water is directly injected into the gas turbine, along with fuel, such as natural gas or fuel oil. The water helps to reduce the turbine firing temperature, which results in a reduction in NOx emissions. Using demineralized water means that there will be minimal scaling and build-up in the nozzles and combustion chamber. As the load increases, more water is added to maintain the turbine firing temperature and reduce NOx emissions to about 25ppm. For precise control, a flow meter is required and the FT Series turbine meter is an ideal choice with accuracies of up to 0.1% of reading.
The FT Series turbine meter is used with the LA-5 linearizing electronics to give an extended range calibration that provides a turndown of 100:1 over the flow range. The meter can be supplied with either meter-mounted or remote-mounted electronics. High-temperature amplified pickoffs are used to reduce noise generated by the non-grounded electrical system of the turbine generator. The FT Series turbine meter is compact and can be located inside the generator room due to its ability to withstand extreme conditions, making it the perfect solution for your gas turbine generator.
