Which component is responsible for controlling the temperature in a high-pressure boiler?

The component responsible for controlling the temperature in a high-pressure boiler is the temperature controller. This device continuously monitors the temperature of the boiler’s water and steam, and it adjusts the heat input to maintain the desired temperature setting. The temperature controller works by receiving feedback from temperature sensors, enabling it to make real-time adjustments to fuel or energy input, ensuring that the boiler operates efficiently and safely at the required temperature levels.

A safety valve, while critical for safety by preventing excessive pressure build-up, does not regulate temperature. The pressure switch primarily monitors pressure levels, triggering shutdowns or alarms if pressure exceeds safe limits, but it does not provide temperature control. The water level sensor monitors the water level to ensure safe operation, preventing the boiler from running dry, but it does not influence the temperature of the water or steam within the boiler.
