At the end of the acid cleaning, the boiler surfaces will be of bare metal and most of the copper spread around as elemental plating. During rinsing, exposed steel will "flash-rust". The passivation process will remove the flash-rust and copper in a step-by step process, finally impressing a positive potential on the steel exceeding the passive potential but not exceeding the transpassive
In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of
