What are common components found in boiler control systems?

Common components found in boiler control systems include controllers, sensors, and actuators, which are essential for regulating the operation of the boiler efficiently and safely. Controllers manage the various functions based on input from sensors, which monitor parameters such as temperature, pressure, and water level. Actuators respond to the controller's signals to adjust mechanical components like valves and dampers to maintain optimal operating conditions.

The other options do not encompass the necessary elements that facilitate the control and optimization of boiler systems. While gauges and valves play a role in monitoring and managing the boiler's operation, they do not provide the full range of control capabilities offered by the combination of controllers, sensors, and actuators. Similarly, while heat exchangers and pumps are important in the overall boiler system, they serve specific functions rather than the comprehensive control of the system. Lastly, boiler insulation and decoration materials are not functional components of the control system itself; rather, they serve to improve energy efficiency and aesthetic appeal, respectively. Therefore, the option highlighting controllers, sensors, and actuators accurately captures the critical elements of boiler control systems.
