What is the function of a primary air fan?

The primary air fan plays a crucial role in supplying the necessary air for combustion in a boiler. Adequate air supply is essential for the combustion process to occur efficiently, allowing the fuel to burn properly. This involves providing the right amount of oxygen required to react with the fuel, which directly influences the efficiency of the combustion and the overall performance of the boiler.

In the context of a boiler system, proper combustion is vital for optimizing fuel use and minimizing emissions. The primary air fan ensures that the air reaches the combustion chamber at the correct pressure and velocity, facilitating an effective combustion process. Without this fan, the combustion process would be insufficient, leading to incomplete burning of fuel and potentially causing operational issues, such as increased emissions and reduced efficiency.
