heat loss negligible cyclone 21 heat lost via radiant heating produces energy heat lost in fly ash produces energy net energy produces unusable energy heat loss significant baghouse 22 heat loss via radiant heating produces energy heat lost in fly ash produces energy net energy produces unusable energy heat loss significant acid gas scrubber 23 heat loss via radiant heating produces energy heat lost in quenching gas with caustic produces energy solution net energy produces unusable energy heat loss significant carbon dioxide scrubber 24 heat loss via radiant heating produces energy heat loss via compressive heating produces energy heat lost in cryogenic chilling produces energy net energy produces unusable energy heat loss significant heat balance heat produced 100 heat used to produce steam 88 heat loss through radiant convection 10 heat loss from ash 2 heat loss through combustor fire tube lt 0 001 and boiler to ensure that the heat loss from heating unnecessary oxidant and diluent is minimized the quantity of oxygen and carbon dioxide at each point of the combustion process is stringently controlled this control benefits the combustion process in three ways the first way is by minimizing the heat loss in the combustion process this minimizes the amount of carbon monoxide produced carbon monoxide a priority pollutant is produced indirectly proportional to the combustion temperature therefore by maximizing the temperature while maintaining a slight excess of.
