Steam leaves the boiler through piping to transfer heat to something; usually a heat exchanger or steam jacket. When the steam condenses in the pipe it is called condensate. This condensate water has very little impurities in it. In fact, condensate is practically pure, clean water… and it's very hot, which makes it the perfect fit for

In modulating steam generation systems, feedwater flow is controlled by varying the speed of the feedwater pump using a variable speed drive. Flow varies directly with speed because Clayton Industries uses a positive displacement pump. For example, at 40% of boiler output, the pump runs at 40% of full/maximum speed.

Return condensate is distributed on a tray to generate flash steam. The flash steam helps remove any residual oxygen in the condensate return, as well as the incoming boiler feed water. Large boiler systems with higher boiler feed water rates may utilize a vacuum system. These tend to operate at 212 0F or less. A vacuum pump or steam ejector is used to pull nearly full vacuum on a spray tower to remove …

Jun 25, 2014 · So if the boiler were in a dry cleaner's shop producing, say, 90 psi, the pump would have to discharge at 100 psi. Most condensate pump manufacturers set their standard pumps to discharge at 20 psi. This is good for a low pressure system that can operate up to 15 psi (15 psi + 5 psi = 20 psi).

A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.
