What is an economizer?

Explanation:
An economizer is a heat exchanger that recovers energy by transferring heat from hot exhaust gases to a cooler stream, typically preheating boiler feedwater or intake air. By using this recovered heat, the system requires less fuel or energy to achieve the desired process conditions, improving overall efficiency and reducing energy consumption. It isn’t a valve for regulating pressure, a device for measuring humidity, or a pump for circulating coolant, which are different components serving other roles.
