What is the primary function of the air register in a combustion system?

• A. To regulate fuel flow
• B. To admit combustion air and mix it with fuel oil
• C. To increase burner pressure
• D. To filter impurities from the fuel

Answer: (B)

The primary function of the air register in a combustion system is to admit combustion air and mix it with fuel oil. This component plays a crucial role in ensuring that the correct amount of air is supplied for efficient combustion when the fuel is burned. Proper mixing of air and fuel is vital for achieving optimal combustion efficiency, which helps to minimize unburned fuel and reduces emissions. Effective air-fuel mixing leads to a more stable flame, better heat output, and improved overall performance of the combustion system. Understanding this function is essential for maintaining the combustion process, as the air register adjusts the air supply to support various operating conditions, such as load changes or fuel characteristics. This makes the air register a critical element in achieving the desired combustion characteristics and ensuring the system operates effectively.
