The economizer plays a crucial role in enhancing the overall thermal efficiency of a boiler system by preheating the feedwater that is supplied to the boiler. In a typical boiler operation, energy is lost through the exhaust gases as they exit the system. The economizer captures some of this waste heat and uses it to warm the incoming feedwater. This process reduces the amount of fuel needed to reach the required steam production temperature because less energy is required to heat the preheated water to its boiling point.

By improving the thermal efficiency in this manner, the economizer not only contributes to energy savings but also lowers greenhouse gas emissions, making the boiler operation more environmentally friendly. The increased efficiency can lead to significant cost savings on fuel over time, making the use of an economizer a valuable component in many boiler systems.

Other options reflect different aspects of boiler operation, such as fuel supply efficiency, cleaning procedures, or water consumption, but they do not encapsulate the primary function of the economizer in boosting thermal efficiency through preheating feedwater.
