The subject of the study was the cycle proposed as the "initial thermal cycle structure" during the completion of the project "Advanced Technologies for Energy Generation" with the steam parameters of 650/670 °C/30 MPa. Two configurations of internal reheat were analysed: with a four- and seven-section exchanger. The effect of reheat on the operation of the power unit under a partial load was also analysed, and preliminary calculations of the heat exchange area of the internal reheat were made.}, type={Artykuły / Articles}, title={The effect of the internal reheat application on the efficiency of the 900 MW ultra-supercritical coal-fired power unit}, URL={http://www.czasopisma.pan.pl/Content/94248/PDF/09_paper.pdf}, doi={10.2478/v10173-011-0018-0}, keywords={Internal reheat, Ultra-supercritical coal-fired power units, Electricity generation efficiency}, }
