What is the primary function of an air receiver in a boiler system?

The primary function of an air receiver in a boiler system is to equalize pressure fluctuations. Air receivers are designed to store compressed air temporarily, which helps in regulating the pressure in the system. This ensures a consistent supply of air for the operation of various components within the boiler and the overall heating system.

When air is compressed, it can cause fluctuations in pressure due to the varying demands of the system. The air receiver acts as a buffer, absorbing these fluctuations and providing a more stable pressure level for continuous operation. This is crucial for maintaining efficiency and performance in a boiler system, reducing the risk of stress on equipment and enhancing overall reliability.

While other options mention functions related to steam storage, condensate collection, and water level monitoring, these do not accurately reflect the role of an air receiver. An air receiver does not store steam or collect condensate; these tasks are typically handled by specific components like steam drums or condensate tanks. Monitoring water levels is a function related more to the boiler’s water management system rather than the air receiver itself. Thus, the role of the air receiver primarily focuses on managing pressure variations in the system.
