What is the purpose of the diffuser in an air register?

• A. To increase airflow
• B. To provide primary mixing of fuel droplets with air
• C. To regulate temperature
• D. To filter impurities from air

Answer: (B)

The purpose of the diffuser in an air register is primarily to facilitate the mixing of air with fuel droplets to ensure efficient combustion in systems such as burners. By providing this primary mixing function, the diffuser helps create an optimal air-fuel mixture, which is essential for achieving the desired combustion efficiency and performance. In many applications, especially in combustion systems, the quality of the air-fuel mixture significantly influences the system's overall efficiency and emissions. The other functions mentioned in the incorrect options—such as increasing airflow, regulating temperature, or filtering impurities—are not the primary roles of a diffuser in an air register. While airflow and temperature regulation might be influenced by various components in a heating or combustion system, they are not the direct responsibilities of the diffuser itself. Additionally, filtering impurities is typically managed by different components, such as air filters, rather than a diffuser designed for mixing air and fuel.
