Superheater - Wikipedia

2020-9-3 · A convection superheater is located in the convective zone of the furnace usually ahead of economizer ( in the path of the hot flue gases). These are also called primary superheaters. A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system.
