Economizer
A heat exchanger that lowers the flue gas temperature of a boiler, recovers that low-grade heat and provides additional fuel savings.
By definition, an economizer is a heat exchanger that lowers the flue gas temperature of a boiler, recovers this low-temperature heat and provides additional savings in fuel.
Energy recovery with economizers holds a critical position today, both for maintaining competitiveness by reducing costs and for sustaining environmental awareness by reducing emissions.
The most important parameter limiting recovery in economizers is low-temperature corrosion on the flue gas side.
Typical Applications
- Boiler feed water or combustion air heating
- Process or heating water generation
- Additional energy recovery from cogeneration stacks
- Heat recovery from marine engine stacks
- Heat recovery from furnace stacks
