The main purpose of boiler blowdown is to remove impurities and maintain water quality. In a boiler system, water is heated to produce steam, but during this process, various minerals and contaminants can accumulate, leading to a buildup of sludge or scale. These impurities affect the efficiency and operation of the boiler, potentially causing issues such as overheating, reduced heat transfer, and even equipment failure.

Regular blowdown is performed to eliminate a portion of the water from the boiler, thereby reducing the concentration of dissolved solids and other contaminants. This practice helps maintain the chemical balance of the boiler water, ensuring optimal performance and longevity of the equipment. By keeping the water quality in check, blowdown contributes to the safe and efficient operation of the boiler system, preventing potential operational issues.

The other options do not accurately reflect the primary function of blowdown. While blowdown can have a secondary effect on steam production by maintaining overall efficiency, increasing steam production is not its main purpose. Cooling down the boiler, while potentially a side effect of removing hot water during blowdown, is not the goal of this process. Additionally, blowdown does not serve to reduce pressure in the system; instead, it is primarily focused on water quality management.
