Air Venting Theory | Spirax Sarco

Air is present within steam pipes and steam equipment at start-up. Even if the system were filled with pure steam when used, the condensing steam would cause a vacuum and draw air into the pipes at shutdown. Air can also enter the system in solution in the feedwater. At 80°C, water can dissolve about 0.6% of its volume, of air.

Deaeration - an overview | ScienceDirect Topics

Though not a direct part of the boiler, this provides mechanical-type deaeration for the removal of the dissolved gases (CO 2 and O 2) that are highly desirable for a boiler's safe operation. The same is accomplished prior to dose chemical oxygen scavengers (hydrazine) by heating feed water by steam to reduce the concentration of oxygen and carbon dioxide from the feed water.

CHAPTER 2 Steam Generators

The primary function of a steam generator is to generate steam under pressure, but modern steam generators are also required to do the following: i. Ensure generation of exceptionally high-purity steam by eliminating all impurities from saturated steam. ii.

High-Pressure Steam Cycle and Boiler Water Treatment

The use of steam to preheat boiler feedwater was common when energy was cheap, but using surplus process heat instead (from below the "process pinch" temperature) represents a significant opportunity for improved cycle efficiency.

Power Plant Efficiency – Simulator Laboratory

Excluding hydroelectric power plants, most power generating plants employ a type of boiler and steam turbine. A schematic diagram of a simple steam power plant is shown below: High-pressure steam leaves the boiler and enters the turbine. The steam expands in the turbine and does work which enables the turbine to drive the electric generator.

Scaling in boilers - Lenntech

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.

Steam and Condensate - A basic overview of a steam …

Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle . The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam .
