COKE DRY COOLING PLANT BOILERS In waste heat recovery boiler the steam is produced by utilizing waste heat in the circulating gases coming out of cooling chamber. chamber. The gases first pass through superheater, then through evaporator and then through economizer economizer.. The gases after leaving the economizer pass through cyclones and then re--circulated to the chamber by running the mill re fan.. fan
