Energoprojekt-Katowice SA, Siemens AG and Rafako SA presents their joint concept of the solution which is a 2on1 concept – replacing two unit by two ultra-supercritical boilers feeding one turbine. Polish market has been taken as an example.}, type={Artykuły / Articles}, title={Environmentally Friendly Replacement of Mature 200 MW Coal-Fired Power Blocks with 2 Boilers Working on One 500 MW Class Steam Turbine Generator (2on1 Unit Concept)}, URL={http://journals.pan.pl/Content/105655/PDF/10_paper.pdf}, doi={10.1515/aoter-2017-0030}, keywords={coal fired power plant, flexibility increasing, old units replacement}, }
