Description

Class  F22G : SUPERHEATING OF STEAM


Subclass 1/04: Steam superheating characterised by heating method (exothermal chemical reactions not involving a supply of free oxygen gas, apparatus or devices for using the heat therefrom F24J) with heat supply by hot flue gases from the furnace of the steam boiler by diverting flow or hot flue gases to separate superheaters operating in reheating cycle, e.g. for reheating steam between a high-pressure turbine stage and an intermediate turbine stage
