The water is scrubbed by a large volume of steam and heated to the saturation temperature prevailing at that point. As the water-steam mixture rises in the scrubber, the deaerated water is a few degrees above the saturation temperature, due to a slight pressure loss.

exits the steam generator, the water content is less than 0.25 pounds. It is important to maintain the moisture content of the steam as low as possible to prevent damage to the turbine blading. The Babcock & Wilcox design uses a once through steam

9/11/2020 · Steam turbines are used to generate the majority of the world's electricity and they accounted for about 48% of U.S. electricity generation in 2019. Most steam turbines have a boiler in which a fuel is burned to produce hot water and steam in a heat exchanger, and the steam powers a turbine that drives a generator.

Makeup Water. Most of the furnace heat is absorbed by the boiler tubes, superheater and reheaters. However, some of the remaining heat that would otherwise go out the stack is left to heat the feed water. The economy of the system is increased by adding a bank of tubes to preheat the water. This bank of tubes is called the______________.

Steam produced in any shell-type boiler, where the heat is supplied only to the water and where the steam remains in contact with the water surface, may typically contain around 5% water by mass. If the water content of the steam is 5‰ by mass, then the steam is said to …
Learn MoreA steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.[1] The narrow-tube construction, without any large …

Learn MoreCombined-cycle power plants ( Fig. 2.3) are compound gas turbine–steam turbine systems wherein the extreme hot exhaust from a gas turbine is employed to run a boiler, and the steam thus produced is fed into a steam turbine to generate power. These plants can deliver high power output at efficiencies as high as 50%–60% with low emissions and
