Sweco to design power plant in Hungary

Sweco has been commissioned for engineering design and project management of a Circulating Fluidised Bed (CFB) power plant to be built in connection with a paper mill. The result will be a more efficient and environmentally-friendly process.

Previously, steam for the paper industry in Dunaújváros, Hungary, was supplied via an old 4.5 km transfer line from a nearby steelworks and electricity was purchased from the national grid. Sweco has been selected to build a new power plant under an EPCM contract that gives Sweco responsibility for all engineering design, project management, building contracting and worksite services needed for construction of the new plant.

The plant will produce steam and electricity for the local paper industry in a cost-effective and environmentally-friendly manner. The new CFB steam turbine, with specifications of 80 kg/s, 130 bara and 540 °C, has the capacity to burn waste paper and other by-products from the paper mill and biomass fuels equal to 40 per cent of the plant’s total fuel demand, thereby decreasing the use of coal and reducing carbon dioxide emissions.

The combined energy and heat production from the 49.9 MW steam turbine will increase the overall efficiency. The power plant will have an efficiency of 86 per cent, giving the investment a good payback time while reducing the local environmental load.
