An Economizer is used to increase boiler operation efficiency. It is a waste heat recovery equipment which uses the waste heat from flue gas to preheat feed water.
Economizers can increase boiler efficiency. It is a solution to save fuel, because the higher temperature of incoming feed water reduces the need for additional energy input into the boiler.
• Improved boiler efficiency.
• Increasing the steam raising capacity of the boiler ( by shortening the time required to convert water into steam ).
