The HRS can be optionally supplied with a vent condenser to recover flash steam. Reducing the pressure of saturated condensate will cause a portion of the liquid to flash to low-pressure steam. The flash steam may contain approximately 10-40% of the energy content of …
Unfired steam boilers are used to protect fired boilers from harmful chemicals in the return condensate, such as in pulp and paper processing. Unfired steam boiler tube bundles and/or drum can be fabricated using materials that will be cost effective for the process steam condition. These can range from copper tube …

Water-steam cycle in a high pressure, conventional drum-type plant. Mineral salt contaminants enter the system through condenser tube leaks and atmospheric carbon
The hot water in the condenser is released into the cooling systems, i.e., cooling tower, river, sea, or cooling pond. Condensates collected from these condensers are reused as feedwaters in the boiler. Since cold water and steam do not mix, condensate is reclaimed, and any type of cold water can be used.
•Steam cycle – Begins at the boiler where thermal energy in superheated steam is converted to mechanical energy in the propulsion turbine – Steam is then converted into condensate in the main condenser – Condensate is combined with distilled makeup water …
Steam Generators - Electric & Fuel-Fired A 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.
Steam Generator vs. Steam Boiler | Powerhouse
Mar 27, 2020 · Working of Steam Condenser. The steam condenser receives exhaust steam from one end and gets in contact with the cooling water flowed within it form the cooling tower. As the low-pressure steam comes in contact with the cooling water, it condenses and turns into water. It is attached to the air extraction pump and condensation extraction pump.
Large Steam System Condensers Stainless Steel Condenser Tube. The steam condenser, shown in Figure 9 below, is a major component of the steam cycle in power generation facilities.It is a closed space into which the steam exits the turbine and is forced to give up its latent heat of vaporization.

Flexible Water Tube Boilers from Bryan Boilers High
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
Define water tube boiler. water tube boiler synonyms, water tube boiler pronunciation, water tube boiler translation, English dictionary definition of water tube boiler. n a steam generator consisting of water drums and steam drums connected by banks of tubes through which the water is circulated.
Inside a steam condenser, there is a flow of cooling water which is continuously circulating from condenser to cooling tower and cooling tower to the condenser. So when exhaust low-pressure steam comes from the turbine and passes through the condenser, it (steam) gets condensed to water, as the steam loses the heat, the extracted heat from the
