Double reheat ultra-supercritical thermal power generation technologies

Combined with the current requirements and development situation of ultra-supercritical units, analyze the impact of secondary reheat technology to ultra-supercritical units to improve efficiency and environmental benefits. Steam temperature control is a key to double reheat systems, in addition to improving the material resistance unit, a well-designed control system is essential. 

Common control strategies have reheated steam temperature control regenerative heating system, flue gas baffle and surface heat exchanger regulation, and flue gas recirculation, flue gas bypass baffle and flue gas recirculation.
