What is the role of dilution air in flue gas systems?

Dilution air plays a vital role in flue gas systems by mixing with the exhaust gases produced during combustion. The primary purpose of introducing dilution air is to reduce the concentration of harmful components within the flue gases, thereby lowering the overall emission levels as the gases exit the system. By providing a larger volume of air to mix with the flue gases, dilution air helps ensure that any harmful pollutants are adequately dispersed, contributing to better environmental compliance and safety. This mixing process is essential for optimizing combustion efficiency and reducing the risks associated with hazardous emissions.

While enhancing combustion temperature, eliminating hazardous emissions, and creating a vacuum are important factors in combustion appliance safety, they do not accurately describe the specific function of dilution air in flue gas systems.
