Boiler Hot Water Temperature Setting

  • Passivating carbon steel / when to

    Mar 27, 2009 · To begin with, carbon steel boilers don't rust because the pH of the water is kept above the oxidizing point of steel which is about 8.2 - 8.3. The magnetite coating is a chemically induced conversion coating (also called black oxide), that if left in a pH environment below 8.2 will start to rust.Learn More

  • Economiser in Thermal Power Plant - Electrical4U

    Feb 24, 2012 · You can well understand form the discussion above that, cooling the flue gas below 250 o F and transferring that additional heat to the boiler feed water would have resulted in greater efficiency, but in a coal fired power plant, this should not be done, since coal as a fuel contains sulphur in a very large extent as impurity. And the flue gas thus formed by burning this coal, results in the Learn More
