To eliminate this possibility, some operators may discard hot condensate rather than recycle it as boiler feedwater. With condensate containing around 25 percent of the useful energy in the original steam, recovering it can substantially reduce water, energy, effluent and chemical treatment costs.
During a preliminary inspection of the boilers and auxiliary systems, I noticed that both of the 100 hp boiler feedwater pumps were running.
This was preferable because the temperature differential between the cold water supply and flue gas was greater than if the boiler feedwater had been circulated through the heat exchanger.
