Abstract: Having been put into use in a large domestic coal-fired power plant, through experimental studies this in-depth flue gas waste heat utilization system exhibits remarkable effects on energy saving and emission reduction. Under the 600-MW load conditions, the net standard coal consumption rate is decreased by 4.9 g/(kW·h), and the dust emission concentration is lowered by 7.8 mg/m3 at the electrostatic precipitator outlet with the water consumption substantially being reduced in the wet flue gas desulfurization process. Moreover, the system operation is safe and reliable and the tuning procedures are quite flexible, which shows significant economic and environmental benefits.

Key words: coal-fired power plant, in-depth waste heat utilization, energy saving, net standard coal consumption rate, dust emission concentration, boiler efficiency
