Heating Boiler Blowdown A blowdown sample taken September 1., 1985 from the heating boiler which was placed in use on July 16, 1985 after a considerable period of in-activity, was found to contain an iron concentration of 3.9 PPM. Since chemical treatment of this boiler is made by batch addition, we believe the iron level in the blowdown is due

Steam Pressure Reduction: Opportunities and Issues

Boiler Blowdown Loss. When boiler pressure is reduced, the blowdown loss is also reduced. If the energy from blowdown is being . recovered through a blowdown heat recovery system, there will be no further savings by reducing the boiler pressure. If however, blowdown water is being drained and flash steam is being vented, savings will result

Boiler blowdown - YouTube

Nov 08, 2016 · Most boilers have a bottom drain line with two different valves: a knife valve and a gate valve. The optimum way to blowdown a boiler is to begin with the valves fully closed. Start by opening the knife valve, then open and close the gate valve. This should be done to both back and front valves if the boiler comes equipped.
