- Reheat Cycle in Steam Power Plant and Methods of Reheating - EEEGUIDE
In reheat cycle in steam power plant, the steam is taken out from the turbine and it is heated by the flue gases in the boiler The main purpose of reheating is to increase the dryness fraction of steam passing through the lower stages of the turbine
- Superheat and Reheat – Rankine Cycle - Nuclear Power for Everybody
One of the possible ways is to superheat and reheat the working steam Both processes are very similar in their manner: Superheater – increases the steam temperature above the saturation temperature; Reheater – removes the moisture and increases steam temperature after a partial expansion
- Reheat Steam Cycle - an overview | ScienceDirect Topics
The HP cylinder exhaust steam must be sufficiently superheated to avoid any wetness in the cold reheat pipework, which would cause severe erosion As in the previous section, the exhaust steam from the LP cylinder must be wet, but not greater than 12% wetness
- What is Superheat and Reheat – Rankine Cycle - Thermal Engineering
One of possible ways to increase thermal efficiency is to superheat or reheat the working steam For this purpose superheater or reheater must be used Thermal Engineering There are several methods, how can be the thermal efficiency of the Rankine cycle improved
- Steam Power Plants 3- THE IDEAL REHEAT RANKINE CYCLE
Superheat the steam to very high temperatures before it enters the turbine This would be the desirable solution since the average temperature at which heat is added would also increase, thus increasing the cycle efficiency This is not a viable solution, however, since it requires raising the steam temperature to unsafe levels 2
- Super heated steam - Nuclear engineering | Eng-Tips
The steam itself is used in secondary heat exchangers to reheat cooler steam Wet steam would destroy the turbines After the steam generators have created the steam, it passes through a series of moisture separators to dry the steam before going to the high pressure turbine
- Explain the reheat cycle in steam power plants.
Nuclear power plants where reheating is essential to manage steam quality Supercritical and ultra-supercritical plants commonly employ double or triple reheat cycles for maximum efficiency Practical Considerations Reheating requires extra boiler surfaces, increasing equipment size and cost
- Steam vapour cycles - heatandwork. com
When heated above its saturation temperature steam is termed "superheated steam" (to the right of the water-vapour curve) When cooled below its saturation temperature water is termed "subcooled water" (to the left of the water-vapour curve)
- Superheated Steam - Spirax Sarco
Superheated steam has to cool to saturation temperature before it can condense to release its latent heat (enthalpy of evaporation) The amount of heat given up by the superheated steam as it cools to saturation temperature is relatively small in comparison to its enthalpy of evaporation
- Reheat Attemperator Spray - Emerson
In order to increase the thermal efficiency of a steam generator and improve the overall heat rate of a unit, what is called reheat is incorporated into the power cycle Reheat involves steam that is extracted from a turbine prior to complete expansion
