Finnish technology company Valmet is to deliver a flue gas condensing heat recovery system to Veolia's EC4 combined heat and power plant in Łódź, Poland, as part of the utility's HeatUp! decarbonisation programme.
The system will capture more than 50 MW of energy from flue gases and feed it into the city's district heating network, with projected CO2 savings of over 82,000 tonnes per year.
Veolia says renewable heat production at EC4 will increase by a third without any increase in biomass consumption.
Valmet's scope of supply covers three flue gas condensing stages designed to maximise heat recovery, a condensate treatment system to produce raw water for use in plant processes, and an extension to the existing Valmet DNA automation system already installed at the site. Start-up is scheduled for the third quarter of 2027.
The project forms part of Veolia's broader GreenUp decarbonisation strategy for the Łódź district heating system, which also includes a planned gas-fired unit and heat accumulator.
Together, the investments are intended to eliminate coal combustion in the city entirely from 2031.
Valmet director Lari-Matti Kuvaja said the project demonstrated the benefits of integrating condensing heat recovery with high-efficiency heat pumps, and of sourcing both automation and process technology from a single supplier.
The order was included in Valmet's fourth-quarter 2025 order intake. Financial terms were not disclosed.
