2020-3-17 · The increase in overall efficiency of the boiler plant varies from 2 to 10 percent when an air pre-heater is used. This increase depends on location, rating and on the fact that whether other heat saving devices are employed or not. Draught losses in the pre-heater varies between 60 to 100 mm of water at the usual maximum output of the boiler.
