What Is an Economizer?
An economizer is a device designed to recover heat from exhaust gases for preheating boiler feedwater in heating systems.
The operational principle involves the transfer of heat from exhaust gases to the feedwater through a heat exchanger. This process preheats the feedwater, improving the overall energy efficiency of the boiler system.
Economizers are primarily used in various settings, including power plants, factories, buildings, and apartments. Their implementation leads to fuel savings and reduced exhaust emissions. There are two main types: the heat exchanger method, which uses tube-type heat exchangers, and the heat recovery boiler method, which employs plate-type heat exchangers.
The advantage of relatively low-cost implementation makes economizers an environmentally friendly choice, contributing to both energy savings and reduced emissions. When using economizers, it is crucial to select the appropriate model based on performance and specifications, ensure correct installation, and prioritize safe usage.
