regeneration topic in thermal engineering
Dear Student,
Significant increase in the thermal efficiency of steam turbine power plants can be achieved by reducing the amount of fuel that should be added in the boiler.
This can be done by transferring heat (partially expanded steam) from certain sections of the steam turbine, which is normally well above the ambient temperature, to the feedwater.
This process is known as heat regeneration and a variety of heat regenerators can be used for the same purpose.
Also, Sometimes engineers use the term economiser which are heat exchangers, intended to reduce energy consumption, especially in case of preheating of a fluid.
Happy Learning!
