What is the function of a boiler ignition system?

The function of a boiler ignition system is to initiate the combustion process within the boiler. This system is essential for starting the boiler by igniting the fuel, which may include natural gas, oil, or other types of fuel. Once the ignition system successfully initiates combustion, it ensures that the fuel mixes with air and is ignited to produce heat, raising the temperature of the water or steam in the boiler.

While controlling the temperature of the boiler, draining excess water, and monitoring pressure levels are important functions in the overall operation and safety of the boiler, they are not the primary role of the ignition system. The ignition system's primary focus is on the crucial first step of ignition, which sets the stage for all subsequent processes within the boiler system.
