A heat sensor installed at the Tokai Cobex factory in Vénissieux
A new installation, allowing the capture of heat rejected by the Tokai Cobex factory in Vénissieux, was put into service this Tuesday, November 4.
A new installation is designed to capture the heat released by the furnaces at the Tokai Cobex plant in Vénissieux. To limit the emissions of hot fumes from the combustion of graphite blocks, a new system has been installed at the Vénissieux plant. Commissioned today, this new installation will capture the heat emitted by the chimneys by intercepting the fumes.
But how exactly does this system work? Once intercepted by the device, the fumes are directed to a high-performance heat exchanger, transferring the heat to the water. The superheated water is then piped into the Lyon metropolitan area's district heating network. Once the heat has been recovered, the fumes, which were previously expelled through the chimney at 155°C, are released at a reduced temperature of 60°C.
Designed by EDF subsidiary Dalkia, the device should make it possible to recover 4 MW of waste heat and avoid the emission of 8,000 tonnes of CO2 annually.
The cost of this project, mainly financed by the Lyon Metropolitan Area, amounts to 5.4 million euros.
