Economizer: It is also known as a feedwater heater. It is a device in which the waste heat of the flue gases is utilized for heating the feed water.

Superheaters: It is used to dry the wet steam and raise the steam temperature above its saturation temperature. It is generally placed in the path of the furnace gases to utilize the heat from the hot flue gases.
Air Preheater: It is used to increase the temperature of the air before it enters the furnace. It is generally placed after the economizer; so that the flue gases pass through the economizer and then to the air preheater.
Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets from the air or other gases in smokestacks and other flues.

Pre-heating of the Feedwater
The correct answer is option 'B', which states that economizers are used for the pre-heating of the feedwater. Here is an explanation of why economizers are used for this purpose:
What is an Economizer?
An economizer is a type of heat exchanger that is used to recover heat from the flue gases of a boiler. It is typically installed between the boiler and the chimney and helps in increasing the overall efficiency of the boiler system.
Pre-heating of Feedwater
One of the main functions of an economizer is to pre-heat the feedwater before it enters the boiler. By pre-heating the feedwater using the heat recovered from the flue gases, the economizer helps in reducing the amount of fuel required to heat the water to the desired temperature in the boiler.
Benefits of Pre-heating Feedwater
- Pre-heating the feedwater using an economizer helps in reducing the energy consumption of the boiler system.
- It also helps in increasing the overall efficiency of the boiler by utilizing waste heat that would otherwise be lost through the chimney.
- By pre-heating the feedwater, the economizer helps in reducing the thermal shock to the boiler and extends its lifespan.
Conclusion
In conclusion, economizers are primarily used for the pre-heating of the feedwater in a boiler system. This helps in improving the efficiency of the boiler and reducing energy consumption.
