Power Boiler Feedwater and Steam - Convergence Training
In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated and changes to steam, free oxygen is released, carbon dioxide is released from the solids, and the solids drop out (precipitate). 2.2.3 As the steam is used in the end process, it cools and condenses
If you have a steam boiler, your boiler system produces steam. 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
Mar 28, 2016 · The boiler starts, raising condensate temperature to 212 degrees at sea level. Steam generation begins and the water expands, minutely increasing the volume in the boiler. Suddenly the volume expands about 160 times as steam moves from the boiler into the header and system piping. The water level drops as more and more water becomes steam.
Sizing boiler feed units vs. condensate return units - Xylem Applied Water Systems - United States
Condensate return. As steam is generated, the water within the boiler evaporates and is replaced by pumping feedwater into the boiler. As the steam passes around the system to the various items of steam-using plant, it changes state back to condensate, which is, essentially, very good quality hot water.
STEAM PREHEAT. A steam preheat assembly is recommended if the blended makeup/condensate return temperature is lower than 140F. This component includes a self contained temperature control valve, check valve, and copper sparge tube to evenly distribute the steam under the water line of the feedwater system. ELECTRICAL OPTIONS
The water supplied to the boiler, which is converted to steam, is called feedwater. This feedwater system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it then returns it to the power boiler steam drum. The power boiler control system maintains the proper flow of feedwater to the boiler.
The Superior Boiler package condensate return and feed water units are completely automatic systems for the recovery of condensate and the feeding of boilers.
