The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.
