As the name suggests, an economizer is a mechanical device used to economize the process of electrical power generation.
Function of the economizer:
Economizer works as a heat exchanger by preheating a fluid which as a result minimizes energy consumption.
In a steam boiler, it heats the fluid and recovered residual heat which in turn is used to preheat the boiler feed water that is ultimately converted to superheated steam. In this way, it saves fuel consumption and gathers the residual heat to use it wherever it is required.
In addition to this, the economizer also used the heat produced from the combustion of the flue gases before releasing them through the chimney.
Power plant engineering is also known as power station engineering that copes with the production, transmission, sharing and usage of electric power. In this process, energy from chemical forms like c...
