Which one of the following groups of devices are used for part recover...
Superheaters: It is used to dry the wet steam and raise the temperature of the steam above its saturation temperature. It is generally placed in the path of the furnace gases so as to utilize the heat from the hot flue gases.
Economizer: It is also known as feed water heater. It is a device in which the waste heat of the flue gases is utilised for heating the feed water.
Air Preheater: It is used to increase the temperature of air before it enters the furnace. It is generally placed after the economiser; so that the flue gases pass through the economiser 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 air or other gases in smokestacks and other flues.
Boiler Drum is a pressure vessel it is used to Separate steam and water mixture.
So super heaters, economiser and air preheater are used for part recovery of heat from the flue gases.

Which one of the following groups of devices are used for part recover...
Answer:
The correct answer is option D, which includes superheaters, economisers, and air preheaters. These devices are used for part recovery of heat from the flue gases leaving the tube banks in a water tube boiler.
Superheaters:
- Superheaters are devices in a boiler that increase the temperature of steam beyond its saturation point.
- They are typically installed in the path of flue gases before the gases exit the boiler.
- Superheaters recover heat from the flue gases by transferring it to the steam, increasing its temperature and energy content.
Economisers:
- Economisers are heat exchangers that recover heat from the flue gases and transfer it to the incoming feedwater.
- They are placed in the flue gas path after the boiler's combustion chamber but before the chimney.
- Economisers preheat the feedwater, reducing the energy required to raise its temperature to the desired level.
Air Preheaters:
- Air preheaters are devices that recover heat from the flue gases and transfer it to the incoming combustion air.
- They are typically installed in the path of flue gases before they enter the chimney.
- Air preheaters preheat the combustion air, increasing the efficiency of the combustion process and reducing fuel consumption.
Explanation:
- The flue gases leaving the tube banks in a water tube boiler contain a significant amount of heat energy.
- By using superheaters, economisers, and air preheaters, a portion of this heat can be recovered and utilized, increasing the overall efficiency of the boiler system.
- Superheaters recover heat from the flue gases by transferring it to the steam, increasing its temperature and energy content.
- Economisers recover heat from the flue gases and transfer it to the incoming feedwater, preheating it before it enters the boiler's combustion chamber.
- Air preheaters recover heat from the flue gases and transfer it to the incoming combustion air, increasing the efficiency of the combustion process.
- By utilizing these devices, the heat energy in the flue gases is maximized, resulting in reduced fuel consumption and improved overall thermal efficiency of the boiler system.
