In a gas turbine, the production of which compound is reduced by water injection systems?

• A. Carbon dioxide
• B. Ozone
• C. Nitrogen oxides
• D. Sulfur dioxide

Answer: (C)

In gas turbines, water injection systems are primarily used to reduce the formation of nitrogen oxides (NOx). During the combustion process, reaching higher temperatures leads to the formation of NOx due to the reaction between nitrogen and oxygen in the air. Water injection helps to lower the combustion temperature and increases the overall cooling effect in the combustion chamber. This cooling minimizes the potential for NOx formation since these compounds are produced predominantly at elevated temperatures. By introducing water into the combustion process, the temperature is reduced, helping to prevent the thermal conditions that favor NOx generation. This approach is vital for meeting environmental regulations and reducing the emissions of harmful pollutants from gas turbines, making it an effective strategy for clean energy production.
