  Abstract Text

  In 2006 ALSTOM was awarded a contract for a study for increase of power output, efficiency and availability on the Power Plant TE NT A, unit 6. In another contract was performed a study for the Power Plant TE NT B, unit 2 in 2007 with the same aims. Both plants are lignite fired. Forming a joint team of EPS and ALSTOM the three units have been assessed and areas for potential improvements have been defined. The potential improvements are mainly focused on: - Increase of unit power output based on increased main steam generation in the boiler and modernisation of steam turbines - Increase of unit efficiency based on improvements in Ljungstroem type air preheater, electrostatic precipitator, boiler feed pump and steam turbine - Increase of availability based on a change in maintenance strategy - Necessary adoptions and modernisations of other equipment like alternator, pulverisers, pumps, fans, piping etc. in order to meet the requirements of an increased power output. In a first phase after the assessment the jointly defined potentials have been elaborated conceptually and the economic effects have been defined. Based on those economic effects several potentials have been selected for further elaboration in detail during the phase 2. It has been defined, that the unit power output can be increased in the range of 10 % mainly based on the increased steam generation in the boiler while the efficiency increase is based on steam turbine modernisations and improvements in the equipment as mentioned above. Based on these results principle examples will be explained in detail. The approach used by EPS and ALSTOM in this study and the further project execution is of wide interest for other power plant owners as it can be easily used and grant improvements in power plant output, efficiency and availability. « hide
