Economizer

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases and transfer it to the boiler feedwater. This raises the temperature of the boiler ...

What is an Economizer? How an Economizer Works

Stack economizer. A stack economizer recovers some heat for pre-heating water. This water is either used for make-up water or another need within the boiler system. This type of economizer is an efficiency measure when large amounts of make-up water is involved or when large amounts of hot water is needed somewhere else.

Why is an economiser used in a boiler?

10/18/2017 · As the name may imply, the Economizer is a device built into a boiler to help improve the economy of the boiler. The water heading into the boiler has typically been preheated by some steam flow that was extracted, or bled, from the steam turbine. This water is under very high pressure, and enters the boiler inside high pressure water lines.
