What is the purpose of a boiler economizer?

1. To reduce water usage

2. To recover waste heat

3. To increase steam production

4. To enhance insulation

The correct answer is: To recover waste heat

The purpose of a boiler economizer is primarily to recover waste heat from the flue gases that exit the boiler. By capturing this heat, the economizer increases the overall efficiency of the boiler system, allowing it to use less fuel to produce the same amount of steam or hot water. This not only reduces operational costs but also minimizes the environmental impact by decreasing greenhouse gas emissions associated with fuel combustion. In contrast, while the other options may seem relevant, they do not accurately represent the primary function of a boiler economizer. Reducing water usage pertains more to water management systems rather than heat recovery. Increasing steam production typically relates to boiler capacity and design rather than directly to economization. Enhancing insulation is an important aspect of energy efficiency but does not pertain specifically to the function of an economizer.
