What is the function of the bottom blowdown valve?

To control steam pressure
To dump the boiler
To add water
To ignite fuel

The correct answer is: To dump the boiler

The function of the bottom blowdown valve is primarily to remove accumulated sludge, sediment, and other impurities from the bottom of a boiler. This process is essential for maintaining the efficient operation of the boiler, as it prevents the buildup of debris that can lead to corrosion or overheating. By "dumping the boiler," the valve facilitates the safe expulsion of these unwanted materials, ensuring that the boiler operates smoothly and effectively. The other options, while relevant to different aspects of boiler operation, do not accurately describe the role of the bottom blowdown valve. Controlling steam pressure, adding water, and igniting fuel each pertains to different systems and valves within the boiler operation, but they are not functions of the bottom blowdown valve. This valve specifically focuses on maintaining water quality and operational efficiency rather than controlling steam pressure or fuel management.
