Local public company Chartres Métropole Énergies in charge of heat and electricity production and distribution in Chartres urban area recently launched upgrading and extension work on its urban heating network. Clévia’s teams were appointed to build a biomass-fuelled power plant to supply the city of Chartres and surrounding communities.
Gellainville (28) cogeneration plant is to supply heat and electricity from wood biomass combustion (including woodchip, prunings, bark etc.) and waste or reclaimed wood from demolition, packaging and collection. The system installed by our specialists will operate by co-incineration, enabling energy to be supplied from reclaimed wood (75%) and wood chip (25%).
The water-steam cycle designed by our teams of industrial heating specialists includes a steam turbine (with vacuum condensing) combined with an air condenser. This system should enable the heat surplus produced to be transformed into electricity. Our staff are also to commission a heat exchanger (or steam condenser) enabling the injection of hot water at 105 ° C into the city’s heating network.
By optimizing utilities production (or energy fluids like reverse osmosis-purified water, cooling water and dried compressed air) Gellainville power plant will produce sustainable energy in total compliance with current environmental standards.
The project will be delivered in February 2019.
