CFB Boiler: Credit: Valmet

Valmet will deliver a multifuel boiler plant to Veolia Energie in Prerov in the Czech Republic. The new boiler will replace an old coal-fired unit and strengthen Veolia’s strategy to move toward more environmentally friendly production of district heat and electricity.

“…We will even reuse the existing boiler house to help reduce not only CO2 emissions from energy production but also from constructing the power plant. With flexible use of biomass and waste in all possible mixtures, the plant is fit for the challenging energy transition,” says Jari Niemelä, director, boilers and gasifiers, Valmet.

Valmet’s delivery scope includes a 40MWth Valmet BFB Boiler utilising bubbling fluidized bed combustion technology. The boiler steam production is 52 t/h at 4.2 MPa(g) and 420°C. The multifuel boiler is designed to run from 0 to 100% on refuse-derived fuel (RDF) and/or biomass.

Additionally, the delivery includes a flue gas cleaning system, refurbishment of an existing steel structure and its modification, electrification and instrumentation, as well as an upgrade of an existing automation system.

“We chose Valmet based on the criteria of public procurement, in other words, on the combination of price and operational costs for 15 years. Valmet has a high number of running references and long experience with boilers. That is why we trust Valmet and already cherish our future relationship,” says Jaromir Novak, head of technical department, Veolia Energie ČR.

Veolia Energie is one of the largest independent producers of electricity and district heat in cogeneration in the Czech Republic and will take over the boiler plant in January 2023.
