Polish energy company to bring 460MW coal-biomass power plant on line in 2009
Poland's second largest power group, Poludniowy Koncern Energetyczny (PKE), announces it will put on line a new coal and biomass fired 460 MW power station in Bedzin in the first quarter of 2009. Construction on the €500 (US$735) million plant began in January 2006 and is now in its final stages. The power station will burn 1.2 million tonnes of coal and renewable biomass per year. The biomass component and an efficient combustion system ensures that emissions are reduced by 25 per cent compared with the country's most efficient generators.
Bedzin is a small city located in the South-West of Poland, in the Silesian Voivodship, a forest-rich area, from where biomass will be supplied for co-firing. The electricity generated will be fed into a new 400kV power line being built by Energoprojekt Kraków S.A. servicing the large urban agglomeration of Krakow.
The cleaner coal plant will be the least polluting in Poland because it utilizes an efficient fluidized bed combustion (FBC) system, which allows for the flexible use of both coal and biomass. FBCs suspend solid fuels on upward-blowing jets of air during the combustion process. The result is a turbulent mixing of gas and solids. The tumbling action, much like a bubbling fluid, provides more effective chemical reactions and heat transfer.
Partly due to co-firing biomass and to the efficiency of the FBC, both SO2 and NOx emissions will not exceed 200mg/m³, which is in line with EU regulations. The lowered emissions will count as part of Poland's obligations to lower greenhouse gas emissions from industry and energy.
The company created a dedicated website showing progress at the construction site live. In november last year, the last important block of the plant was added, its 133,2 meter high cooling tower. A successful test with cooling water was conducted on 23 November. This allowed for the start of the construction of the boiler segment. The next milestone was the construction of a 60 tonne impeller, as well as the 288 tonne generator, the biggest single element on the block. This year in August the first full firing tests will take place, with synchronisation trials beginning in december:
ethanol :: energy :: sustainability :: biomass :: bioenergy :: biofuels :: coal :: co-firing :: fluidized bed combustion :: Poland ::
The investment in the biomass-coal plant is the first step in PKE's strategy to phase out its older coal power stations. PKE planning to build another two power stations, with capacity of 800 and 1000 MW each. Company spokesman Pawel Gniadek said that by the end of March, PKE would decide on the sites of these and possibly select partners to build them. Partners being included are E.ON, RWE, ESB International, Sempra Energy and JES Energy:
In the long run, PKE plans to maintain its capacity close to the current level, at around 5 GW, but needs to replace old capacity, which does not meet environmental standards.
