Which two types of combustion control systems are modern boilers equipped with?

Modern boilers are typically equipped with throttle control and automatic control systems for combustion management.

Throttle control allows operators to adjust the flow of fuel and air into the combustion chamber, essentially regulating the burner output based on the demand for steam or hot water. This form of control provides a level of manual oversight, ensuring that the combustion process remains efficient and responsive to changes in operational needs.

In contrast, automatic control systems leverage sensors and feedback loops to continuously monitor parameters such as temperature, pressure, and the concentration of combustion gases. These systems can automatically adjust the fuel and air supply, optimizing combustion efficiency and reducing emissions. They enhance safety by responding to fluctuations in operating conditions without the need for constant manual intervention.

Combining these two forms of control helps ensure that boilers operate efficiently, safely, and in compliance with environmental standards.
