Power generation in eastern Germany is mainly based on lignite as a domestic fuel.More than 90% of lignite is converted into electricity in large-scale power facilities; the remainder is used to heat homes and in decentralized facilities.With specific CO₂ emissions of 0.40 kg/kWh-fuel used, CO₂ composes the largest problem regarding lignite acceptance for long-term power generation.For this reason, power facilities were completely modernized over the last 5 years.Besides increasing efficiency, biomass co-combustion offers another important possibility to improve the CO₂ balance of lignite-fired power facilities.At the Schwarze Pumpe Power Station (part of VEAG Vereinigte Energiewerke AG Berlin), wood chip biomass co-combustion has been tested for some time.Development work conducted by VEAG (logistics, operation management, emission behavior with co-combustion) and development work concerning biomass co-combustion in smaller facilities for the decentralized heat supply market is discussed.At the Power Station Technol. chair of Brandenburg University of Technol. Cottbus and the Energy Resource Institute Cottbus, a cycloidal firing system (cyclone firing) for the decentralized heat supply market was developed in co-operation with industrial partners.Lusatian fluidized-bed lignite is the primary fuel.Cycloidal fired combustion occurs in an upward-directed rotational flow.Using this technique makes highly-efficient co-combustion of wood chip biomass possible.Besides reduced CO₂ emissions, fuel substitution offers the possibility to reduce SO₂ emissions such that existing boundary value requirements regarding pollutant emissions can be met without any addnl. flue gas desulfurization.

Experience with the co-combustion of sewage sludge in the Boxberg lignite-fired power plant of VEAG

Author: Mielke, F. ; Brunne, Th. ; Heinze, D. ; Richter, S. ; Wierick, H.-G.

VEAG as largest East German electricity generating company and operator of the interconnected grid is being realizing a number of projects in the field of waste management in order to extend business opportunities.Among the first projects was the investigation of the possible co-combusting of municipal sewage sludge in the existing 500 MW lignite-fired units of the Boxberg power plant.A large-scale test was realized in 1996.The results of this test proved that co-combustion of sewage sludge up to 5% weight together with lignite is not affecting regular power plant operation.Another important result was the unrestricted utilization of residues and byproducts from the viewpoint of emissions.Thus, a plant with a throughput of 2 × 16 t/h sewage sludge was planned and erected in 1998/1999.The first operating experience with this facility has shown that problems have occurred mainly in the field of logistics and with sewage sludge feeding into the boiler.The repeated emission measurements confirmed the results of the large-scale test.The economic targets of the planning phase were largely met in the first calendar years of operation.

Operational and energy optimization of flue gas desulfurization units in the Janschwalde Power Plant

Author: Sparmann, A. ; Welp, H. ; Braun, W. ; Heinze, G.

Measures to optimize the 12 flue gas desulfurization units operated since 1995 at the 3000-MW, lignite-fired Janschwalde power station are described.Scaling in absorbers was essentially decreased by structural and operational changes.Gypsum quality was improved (lower chloride and water content (6.5-7.5%)) without addnl. energy demand.More than 3 MW elec. power were saved by optimizing the pump switching points and decreasing the amount of air for oxidationIn addition, a regime was elaborated that allows to operate the flue gas desulfurization for further 15-20 h after total breakdown of limestone supply.
