Where is the Boiler Safety Valve located?

The Boiler Safety Valve is typically located on top of the steam drum. This is because the safety valve is crucial for preventing excessive pressure build-up within the boiler system. It is designed to open automatically if the pressure exceeds a predetermined limit, allowing steam to escape and maintaining safe operating conditions.

Positioning the valve at the top of the steam drum allows it to effectively monitor the pressure in the steam space, where pressure is most critical. This placement ensures that the valve can operate promptly and effectively, providing a safety mechanism for the boiler system to prevent potential hazards associated with overpressure situations.

The other locations mentioned would not provide the same level of efficiency or safety. For instance, having the safety valve on the ground floor or behind a control panel would hinder its ability to respond to pressure changes quickly since these locations do not directly monitor the pressure environment within the steam drum.
