This article presents the results of a techno-economic analysis of repowering a coal-fired power plant’s steam turbine system to instead accept heat produced by a pressurized water reactor-type small modular nuclear system (PWR SMR). This type of r

Coal-fired power units, now balancing power shortages in the power system, must be characterised by increasingly higher flexibility of operation. This means faster start-ups and the capacity for frequent decreases and increases in the power output. T

The increasing share of renewable energy sources in the overall energy mix forces a change in the character of operation of coal-fired power units. Their task is now to balance the system under variable loads and they have to change from base-to cycl

The changing role of coal-fired power units which are now used more and more often as sources balancing the demand for electricity in the power system calls for a change in the character of their operation. They have to be able to respond appropriate

The paper discusses optimization issues related to start-ups from intermediate states defined as hot and warm, i.e. start-ups carried out after a few or several hours of downtime. Such start-ups are characterized by a non-uniform field of the initial

An efficiency enhancement of coal-fired power units becomes a basis for the reduction in the consumption of primary fuels and as a result in CO2 emissions. Steam parameters increasing is an effective way to improve the efficiency of electricity gener
