Key issues and innovative double-tangential circular boiler configurations for the 1000 MW coal-fired supercritical carbon dioxide power plant

When supercritical carbon dioxide (S–CO2) Brayton cycle is introduced into conventional coal-fired power plant, there exists the problems in S–CO2 boiler configurations due to the working medium physical properties’ change. This paper is taking a typical 1000 MW single reheat double-tangential circular boiler as example and investigations focus on the key issues of S–CO2 power plant with traditional boiler configuration from the thermodynamic...
