What is the main purpose of a blow-off tank?

The main purpose of a blow-off tank is to prevent damage to the sewer. When water is blown off from a steam boiler or a system, it typically contains contaminants, sediment, and high temperatures. Discharging this water directly into the sewer could cause damage to the sewer system or create environmental concerns.

A blow-off tank is designed to safely receive this blow-off water, allowing it to cool down and settle any harmful substances before the water is either discharged into the sewer or treated further. This not only protects the infrastructure of the sewer but also helps in complying with environmental regulations regarding waste disposal.

While regulating steam pressure, increasing water temperature, and storing surplus steam are functions related to boiler operation and steam systems, they do not pertain to the primary role of a blow-off tank, which centers on ensuring safe and compliant waste management.
