Plant Operation Test 2025 – 400 Free Practice Questions to Pass the Exam

The correct answer identifies four essential systems necessary for the operation of a boiler: feedwater, fuel, draft, and steam. Each of these systems plays a critical role in ensuring the boiler functions efficiently and safely.

Feedwater is essential as it is the water that is supplied to the boiler for heating. It undergoes treatment to ensure the removal of impurities, which helps prevent scaling and corrosion within the boiler.

The fuel system is equally important, as it provides the energy source required to generate heat. This can include various types of fuel such as natural gas, oil, or coal, depending on the design of the boiler.

The draft system is crucial for proper ventilation and the removal of combustion gases. It ensures that the necessary airflow is maintained for the combustion process and that any harmful exhaust gases are safely expelled from the boiler area.

Finally, the steam system is responsible for delivering the steam generated by the boiler to where it is needed, such as for heating or powering turbines for electricity generation.

Together, these systems interact to keep the boiler operating effectively, making their presence indispensable in any boiler operation. The other choices incorporate some of these systems but lack a complete representation of all essential components needed for boiler operation.
