Abstract

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 system, in addition to improving the material resistance unit, well-designed control system is essential. Common control strategies have reheat steam temperature control regenerative heating system, flue gas baffle and surface heat exchanger regulation, attemperating water and flue gas recirculation, flue gas bypass baffle and flue gas recirculation.
