Superheater Working Principle

11/17/2017 · Superheater Working Principle – Superheater is a subcritical boiler’s component that heat the saturated vapor, at constant pressure, so it becomes superheated steam. Superheater technology has been used since the use of steam engines early 20th century. The main purpose is to increase the heat energy contained by the steam, so that increasing the thermal efficiency of the engine.

Boiler

Boilers can be classified into the following configurations: Pot boiler or Haycock boiler/Haystack boiler: A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere.

Evaporation takes place in a single pass. This principle used in the BENSON/SULZER boiler, the world's most frequently constructed steam generator type. Flow through the evaporator is induced by the feed pump. The system can therefore be operated at any desired pressure i.e. at either subcritical (Close to critical) or supercritical pressure.

43 PERFORMANCE ANALYSIS OF SUPERCRITICAL BOILER

Subcritical boilers operate below 220 bars, the supercritical pressure of water. homogeneous mixture of water and steam in the evaporator part of the boiler. used because the steam needs to be separated from water before it is superheated and led into the turbine. The remaining water in the drum re-enters the boiler for further conversion to steam.

How Supercritical Power Plant Differ from Conventional Power

In subcritical units the drum acts as a fixed evaporation end point. The furnace water walls act as the evaporator. Not so in the case of a supercritical unit. The evaporation end point can occur in various levels of the furnace depending on the boiler load. The percentage of Superheat in supercritical units is higher than subcritical units.
