BWE-30-0005rev.5 Dimensions: Type: GV 29.0 / 625 Rotor diameter 10.53 m Rotor height 745 mm Rotor speed 1.2 min Heating elements UNF+E Height 400 mm Heating surface 5,815 m Total weight 173 tons -1 2 Untreated Flue Gas: Flow, inlet 292 Nm /s Temperature, inlet 180 °C Temperature, outlet 142 °C Treated Flue Gas: Flow, inlet 322 Nm /s Temperature, inlet 66 °C Temperature, outlet 101 °C 3 3 contributes to the significant improvement in local air quality. The GGH is used to preheat the treated flue gas above the 95 °C required by the legislation in order to secure the necessary lift of the flue gas. The necessary heat for this reheating is taken from the hot untreated flue gases entering the FGD plant. The GGH is of the counterflow rotary regenerative type with a
