Groupe ÉS open new 36 MWth biomass-fired CHP in Strasbourg
Representatives of Électricité de Strasbourg (Groupe ÉS) and the l’Eurométropole de Strasbourg have formally opened the 36 MWth biomass-fired combined heat and power (CHP) facility enabling the French City of Strasbourg to significantly reduce its dependency on fossil fuels for generating heat and power.
The official opening, which took place November 24, marks the completion of the EUR 42 million investment which enables the historic Alsatian city of Strasbourg to significantly reduce its use of fossil fuels for generating heat and power. The plant is designed to generate 70 GWh of electrical power and 112 GWh of district heat per annum, cutting fossil carbon dioxide (CO2) emissions by an estimated 40 000 tonnes per annum.
Thermal energy system provider, France-headed Leroux & Lotz Technologies (LLT), was selected by Dalkia Bas-Rhin, the original developer of the project and since merged with Groupe ÉS’ subsidiary Écotral, to create ÉS Services Energétiques, to design, manufacture, erect and commission the woodchip-fired boiler island ‘chute to stack’ scope.
The combustion system is based on LLT’s in-house design bubbling fluidized bed (BFB) technology to meet tight control on NOx emissions without the need for post-combustion NOx control measures.
LLT capabilities covered both the BFB system, boiler design, and manufacturing along with the supply of ancillary equipment and components such as the surge bin, flue gas treatment, stack, and control system. According to LLT, the project marks its 11th biomass boiler island delivery to date.
