What is one function that a bottom blowdown does not perform?

The function of bottom blowdown primarily involves the removal of sediment, sludge, and other accumulated impurities from the lowest parts of a boiler. By performing this action, it helps to maintain the efficiency of the boiler system, prevent damage, and ensure safe operation.

One of the key purposes of bottom blowdown is also to assist in water treatment by allowing for the regular removal of concentrated solids, contributing to effective water chemistry management. This action thereby helps maintain the appropriate balance of chemicals necessary to prevent corrosion and scaling, which can be detrimental to boiler operation.

While bottom blowdown effectively controls solids concentration by removing sludge and suspended particles, its design and function do not extend to directly assisting with low water problems. Low water level issues are typically addressed via other means, such as automatic controls and alarms, rather than through the bottom blowdown process, which is focused on managing sludge and improving water quality rather than monitoring water levels directly.
