Abstract: The traditional ultra-low emission technology of coal-fired power plants has been difficult to meet the environmental
requirements. Zheneng Jiahua Power Generation Co., Ltd. of Zhejiang conducted a study on deep recovery of flue gas waste heat
based on "ultra-low emission + chimney white smoke elimination". This paper introduced the operation status of the power unit
after adding a flue gas waste heat recovery system to the ultra-low emission system, and systematically analyzed the optimization
measures and methods of deep recovery of flue gas waste heat, which can provide reliable reference experience for the design,
operation and optimization of "ultra-low emission + chimney white smoke elimination".

Key words: ultra-low emission; flue gas waste heat; deep recovery; energy saving and emission reduction
