Description

technical field

[0001] The invention belongs to the technical field of waste heat power generation, in particular to a sinter waste heat efficient recovery power generation equipment and process. Background technique

[0002] The iron and steel industry is an important basic industry of the national economy, and its energy consumption accounts for about 15% of the total industrial energy consumption in the country. It is a key industry for energy conservation and emission reduction. In the process of iron and steel production, the energy consumption of the sintering process is relatively high, generally accounting for 10-12% of the total energy consumption of iron and steel enterprises, second only to the ironmaking process, and has a huge potential for energy saving. In the sintering process, the hot sintered ore discharged from the sintering machine must be cooled to about 150°C before entering the next process. At present, the sinter is cooled by using the air medium thr...
