What is one benefit of using water injection systems in gas turbines besides reducing NOx?

Using water injection systems in gas turbines provides several advantages, and one of the key benefits is that they stabilize the combustion process. When water is injected into the combustion chamber, it can effectively moderate the flame temperature and control the reaction rates within the turbine. This leads to more stable combustion, reducing the likelihood of problems such as combustion oscillations or hotspots, which can be detrimental to the overall performance of the gas turbine.

By maintaining a stable combustion environment, water injection not only helps lower emissions of nitrogen oxides (NOx) but also enhances the overall reliability and efficiency of the turbine. Additionally, a stable combustion process contributes to improved operational consistency, leading to better performance under varying load conditions.

In contrast, decreasing power output, keeping compressor blading clean, and reducing thermal efficiency would not align with the intended benefits of a water injection system. Instead, these systems are specifically designed to improve performance and reduce emissions, making stabilization of combustion a vital element of their operation.
