CHAPTER 2 Steam Generators - EMU Academic Staff

2017-3-22·The water fed into a steam generator is called feedwater. Steam and feedwater together is called working fluid. The name steam generator is also still called boiler, but modern steam generators in the supercritical class do not involve the boiling phenomenon. The fuel-firing equipment of a steam

Why Return Condensate to the Boiler Operation - Swagelok

2017-6-13·One of highest return on investments is to return condensate to the boiler plant. As fuel costs continue to rise, it is imperative to focus on recovering condensate in all industrial steam operations. Condensate contains not only water, but also boiler treatment chemicals and energy that was transferred during the combustion process in the boiler.

How to deal with abnormal boiler pressure? - EPCB

Boiler looks like a simple industrial equipment, but incorrect application may cause large-scale chemical accidents. Boiler pressure gauge is one of the important indicators to reflect boiler state and prevent boiler accidents. If the pressure gauge is abnormal, how to deal with the problem in time? Firstly, we should analyze the causes of pressure gauge []
