What is the primary function of a safety control in a boiler?

The primary function of a safety control in a boiler is to prevent accidents and ensure safe operation. Safety controls are integral components designed to monitor various operational parameters and intervene when those parameters approach hazardous levels. They help manage risks associated with high pressures, temperatures, and other critical operational factors. For example, if pressure exceeds safe limits, a safety control can trigger a shutdown or activate a relief valve, preventing potential explosions or equipment failure.

While optimizing fuel usage, monitoring water quality, and regulating steam pressure are important aspects of boiler operation, these functions are typically part of broader operational or efficiency controls rather than the primary focus of safety controls. The central aim of safety controls is to protect both the equipment and personnel, making their proper functioning essential for safe boiler operation.
