Economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming water.
Boiler efficiency can be increase by 1% for every 5 DegC reduction in flue gas temperature.
Economizer often reduce fuel requirements by 5% to 10%, in term of Monetary Savings.
Important Data & Info for Sizing an Economizer:
- Boiler Capacity
- Boiler Working Pressure
- Fuel Used
- Feed Water Flow-Rate
- Feed Water Inlet Temperature
- Feed Water Outlet Temperature
- Flue Gas Inlet Temperature
- Flue Gas Outlet Temperature
