2020-3-10 · Theoretically, maintaining a high residual of an oxygen scavenger would consume all dissolved oxygen. In reality, competing chemical reactions between oxygen and boiler surfaces are more likely to occur, resulting in significant corrosion within the system. Consequently, maintaining high scavenger levels may not provide adequate protection.

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases. Get a Quote
2012-4-11 · The organization I work for requires that boilers already in operation receive hydrostatic testing every year if steam or high temperature hot water. I have read conflicting information regarding the test pressure the boiler must be brought up to.
In addition to providing many questions (many of which appeared on my licensing exam), this book gives an excellent overview of high pressure boiler operation. This is probably the best companion piece to another text booknow. It's not terribly in depth, what I did was read a text book then read this as a supplement before my exam.
