What are the four main systems/components of a boiler?

The four main systems or components of a boiler are accurately identified as the Draft, Fuel, Steam, and Feed Water System. Each component plays a vital role in the overall functioning and efficiency of a boiler.

The Draft System is crucial for ensuring proper airflow, which is necessary for the combustion process. It helps in maintaining the right balance between fuel and air, allowing for efficient burning and ultimately producing steam.

The Fuel System involves the delivery of the fuel source, whether it be natural gas, oil, or another type of fuel, to the combustion chamber. This system is essential because it dictates the primary energy input into the boiler.

The Steam System is responsible for carrying the steam generated by the boiler to the areas that require heating or process heat. This system allows for the distribution of steam throughout an industrial or heating system.

Lastly, the Feed Water System is critical as it supplies water to the boiler that is needed for steam production. This system also typically includes components for water treatment, which are important for preventing scaling and corrosion inside the boiler.

The other options presented do not accurately encompass the crucial components necessary for boiler operation as comprehensively as the mentioned choice does. Therefore, the identification of these four systems provides a complete and accurate representation of a boiler's main
