An air preheater is installed :
Answer: D
An air preheater is installed between the economizer and chimney.
The flue gases leaving the furnace pass in turn through the superheater, the economiser and then the air preheater before going up the chimney. The air preheater uses the last useful heat in the gases to warm the combustion air, which improves boiler efficiency.
Placing it before the superheater or the economiser would rob those higher-temperature heat exchangers of the heat they need, so they always come first in the gas path.
