The impact of make-up water on your boiler feedwater. In addition to deaeration, it is vitally important to understand boiler feed water quality. Hard water, most notably calcium or lime, will plate out on the boiler tubes and piping under high temperature and pressure. That can lead to two problems: reduced heat transfer, which limits the

The importance of the boiler feedtank, where boiler feedwater and make-up water are stored and into which condensate is returned, is often underestimated. Most items of plant in the boiler house are duplicated, but it is rare to have two feedtanks and this crucial item is often the last to be considered in the design process.
