Characteristics of boiler feedwater - Lenntech

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed …

Types of High Pressure Boilers | Sciencing

The Benson boiler is called a supercritical steam generator and is often used to produce electric power. It operates at such high pressure, more than 3,200 psi, that actual boiling stops and there is no water-steam separation…

DRAFT BOILER/FEEDWATER GUIDELINES

Lake water has approximately 180 ppm of dissolved solids. 1,000,000 pounds of this water will contain approximately 180 pounds of solids. A 100 hp boiler vaporizing 3,450 pounds of this as make-up water would leave behind 0.62 pounds of solids. Well water can have as high as 1,250 ppm of dissolved solids.

7.0 Chemical Treatment - Steam Turbine, Steam Boiler

As a general rule, the higher the boiler pressure, the higher the quality of feedwater required. Therefore, the higher the pressure, the more chemical treatment is concentrated outside the boiler in water preparation (chapter 2), and the less internal boiler water …

      Boiler feedwater - Wikipedia

      History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was “blown down”. It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.
