<P> Fuel flows into the burner and is burnt with air provided from an air blower . There can be more than one burner in a particular furnace which can be arranged in cells which heat a particular set of tubes . Burners can also be floor mounted , wall mounted or roof mounted depending on design . The flames heat up the tubes , which in turn heat the fluid inside in the first part of the furnace known as the radiant section or firebox . In this chamber where combustion takes place , the heat is transferred mainly by radiation to tubes around the fire in the chamber . </P>
