Boiler feed water begins as what type of water?

Boiler feed water typically begins as distilled water, which is a type of water that has been purified through the process of distillation. This process removes impurities, minerals, and contaminants that could otherwise lead to scaling or corrosion within the boiler system. The primary aim of using distilled water is to ensure high quality and efficiency in steam generation and to maintain the integrity of the boiler components.

While rainwater may seem like a viable option, it can contain impurities that affect boiler performance. Wastewater would carry contaminants unsuitable for boiler operations. Seawater, although abundant, contains high levels of salt and other minerals that would be detrimental to boiler systems. Therefore, using distilled water as the starting point for boiler feed water ensures optimal operation and longevity of the equipment.
