What is the function of the steam smothering system?

The steam smothering system is specifically designed to extinguish fires that may occur in the boiler's air casing. In the event of a fire, the system operates by releasing steam, which helps to displace oxygen and effectively smother the flames. This is crucial for safety, as boiler air casing fires can pose serious risks to personnel and equipment.

While other systems may help with boiler efficiency, pressure control, or maintenance cooling, these functions are not the primary role of the steam smothering system. By focusing on fire suppression, the smothering system plays a vital role in maintaining operational integrity and ensuring safety within the boiler environment.
