November 9, 2022 (press release) –

Valmet will rebuild Koehler Paper’s power boilers at its Oberkirch and Kehl paper mill sites in Germany to increase the production of sustainable energy from renewable sources.

The orders were included in Valmet’s orders received of the third quarter 2022. The value of the orders will not be disclosed. The joint value of such rebuilds and supply scopes is typically around EUR 20 million.

In Oberkirch, Valmet will convert an existing circulating fluidized bed (CFB) boiler from combusting coal to biomass. The delivery will be taken over by Koehler in October 2024. In Kehl, Valmet will supply a fuel upgrade on a CFB boiler, and this delivery will be taken over by the customer in September 2023. With the modification, new fuels – mainly sludges – will be added to the existing biomass fuel portfolio.

“By switching from bituminous coal to biomass as the primary fuel for our location in Oberkirch, we will be cutting more than 150,000 tonnes of CO2 emissions a year. By converting away from fossil fuels, Koehler is proactively playing its part in reducing global warming,” says Dr. Stefan Karrer, COO, Koehler Group.

“Valmet is serving customers with solutions for decarbonization and sustainable energy production, and we are happy to share the journey toward a carbon neutral future with Koehler Paper,” says Aleksi Salmirinne, Vice President, Energy business unit, Pulp and Energy business line, Valmet.

The combined heat and power (CHP) plant in Oberkirch produces approximately 100,000 MWh of electric power and 330,000 metric tonnes of steam per year for paper production. The Kehl CFB boiler has a 44 MW thermal capacity, and the plant power generation capacity is 9 MW.

Information about Valmet’s delivery

Valmet's delivery scope to the Oberkirch plant includes boiler modifications and external equipment for converting the coal-fired CFB boiler for biomass; a new biomass feeding system, new burners for renewable fuel, additional heating surfaces, ash removal improvement, a selective non-catalytic reduction (SNCR) system and additive feeding for the baghouse filter.

At the Kehl CHP plant, Valmet will modify the existing CFB boiler and deliver equipment to add paper sludge and sewage sludge to the fuel portfolio of the plant. Sludge feeding systems, bottom and fly ash system upgrades, and modifications to superheaters will be supplied for the Kehl boiler.
