What is the purpose of NOx control technologies in gas turbines?

The purpose of NOx control technologies in gas turbines is to reduce nitrogen oxide emissions during combustion. Nitrogen oxides (NOx) are harmful pollutants that contribute to smog and have adverse effects on health and the environment. Gas turbines operate at high temperatures, which can lead to the formation of NOx as nitrogen in the air reacts with oxygen. Implementing NOx control technologies is crucial for compliance with environmental regulations and to minimize the ecological impact of gas turbines.

These technologies may include alterations in combustion temperature, the use of low-NOx burners, and systems that introduce water or steam into the combustion process to lower peak temperatures. By effectively lowering the production of NOx, these technologies help in promoting cleaner combustion and improving the overall sustainability profile of gas turbine operations.
