Hermann Wenzel Power Station Unit 4 SCR Retrofit, Germany


Hermann Wenzel Power Station is owned and operated by thyssenkrupp Steel Europe and located in Duisburg-Ruhrort in Germany.  The plant consists of four coke and blast furnace gas-fired boilers, which convert the excess blast furnace gas and coke gas from the nearby steel mill to electricity. The 180 MWel Unit 4 is being retrofitted with a high-dust SCR system in order to comply with the stringent German NOx emission regulations.

VPC was awarded the contract by thyssenkrupp Steel Europe for this retrofit and integration into the existing boiler and operating power plant on a turn-key basis including the general planning, detail engineering, technical tender specification, procurement and construction management, startup and commissioning services as well as the trial run and performance acceptance testing.

Technical Data:

·         Electric generating capacity:      1 x 180 MWel gross
·         Fuel:                                          Blast furnace and coke gas
·         SCR configuration:                     high-dust, single reactor
·         Reagent:                                    Aqueous ammonia (24.9%)

Capital Investment:                        €4 million

Client:                                              thyssenkrupp Steel Europe AG


Schedule:                                          2016 – 2018
