Steel sintering waste heat power generation is an energy-saving technology that converts sintering waste gas waste heat resources into electricity. In the production process of sintered ore, especially during the cooling process of sintered ore by a blast ring cooler, a large amount of low-temperature flue gas with a temperature of 200-400 ℃ is discharged, resulting in a waste of a large amount of recoverable heat, which is approximately 33% of the heat consumption of the sintered ore sintering system. The recovery of a large amount of heat energy from low-temperature flue gas waste heat maximizes power generation, thereby improving the energy utilization rate of the sintered ore production process, reducing process energy consumption, and bringing considerable economic benefits to the factory.
