ONCE-THROUGH BOILERS - Thermopedia

Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20-30 bar lower. Sliding pressure operation is adopted to accommodate requirements of part-load running.

Superheated Steam Generators - MHI-INC

What is superheated steam? What is saturated steam? When water molecules exist in a gaseous-state, at a temperature above the boiling temperature of water, it is called the superheated steam-state.. Steam only at the boiling-temperature, is called saturated steam.. The boiling temperature depends on the pressure (e.g. 100°C for 1 atmosphere, or 134°C for 3 atmosphere and so on).

heat - Difference between Superheated steam and

Boilers and similar steam generators usually produce wet steam, which is a mixture of saturated steam and liquid water droplets.Saturated steam is steam that is in equilibrium with liquid water. The temperature of the steam is equal to the temperature of the liquid water; it corresponds to the boiling point at the given pressure.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Saturated steam boiler vs Superheat steam boiler

Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful. This is because superheated steam has the same heat transfer coefficient of air, making it an insulator and poor conductor of heat. Saturated steam is preferred for heating applications, while superheated steam is used mostly in

Boiler - Wikipedia

Energy. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Electric steam boilers use resistance-or immersion-type heating elements. Nuclear fission is also used as a heat source for generating steam, either directly (BWR) or, in most cases, in specialised heat exchangers called "steam generators" (PWR).

Superheated_steam : definition of Superheated_steam and

Superheated steam is steam at a temperature higher than water's boiling point.If saturated steam is heated at constant pressure, its temperature will also remain constant as the steam quality (think dryness) increases towards 100% dry saturated steam. Continued heat input will then generate superheated steam. This will occur if saturated steam contacts a surface with a higher temperature. [1]
