The invention discloses a method for controlling ultralow emission of sintering flue gas, which is characterized by comprising the following steps: and introducing low-temperature sintering flue gas in the large cold air flue into a sintering ore cooling system, raising the temperature of the sintering flue gas by using sensible heat of the sintering ore, introducing the raised flue gas into a waste heat power generation system, and discharging the generated flue gas from a chimney through a main exhaust fan after desulfurization and denitrification. The method for controlling the ultralow emission of the sintering flue gas can reduce the cost of a sintering flue gas emission reduction system, increase the waste heat power generation capacity of a sintering machine and have good application prospects. |
