Modern CoalFired Power Units for UltraSupercritical Steam ... Springer

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...
