Shock Pulse Generator Reference Plant:Waste Heat Boiler – Cokenergy, Chicago / USA

1

• Waste heat boiler with 48 t/h (107klbs/h) steam capacity processingwaste heat from heat recovery cokeovens

• Finned tube design of EVAP and ECOlocated downstream SH

• Each boiler cleaned solely by2xEG10L SPG installed upstream SHand ECO (Shock Pulse Interval = 2h)

• Replaced 12 x steam soot blowers perboiler (type T20, D5E) - saved2.5 t/day of steam per boiler

• Trial run performed in 2016/2017 onboiler D3 – delivered SPGs for batteryA to C (in total 12 boilers) since then

• OEM waste heat boiler:Nooter/Eriksen (commissioned 1998)

• Operator: Cokenergy (SunCoke, USA)
