CONVERTER FLUE GAS RESIDUAL HEAT RECOVERY PROCESS

WIPO Patent Application WO/2019/100648

A1

A converter flue gas residual heat recovery process is disclosed, comprising the following steps: S1. flue gas discharged from a converter is inputted to a first residual heat boiler, and flue gas is discharged after heat exchange in the first residual heat boiler; S2. flue gas discharged from the first residual heat boiler is inputted to a carbon dioxide generating device, and the flue gas is discharged after a spontaneous redox reaction with iron ore; S3. flue gas discharged from the carbon dioxide generating device is inputted to a second residual heat boiler, and flue gas is discharged after heat exchange in the second residual heat boiler; S4. flue gas discharged from the second residual heat boiler is outputted to a heat exchange device, and flue gas is discharged after heat exchange in the heat exchange device; S5. flue gas discharged from the heat exchange device is inputted into a carbon dioxide purification cooling recovery device by way of an electrostatic dust-removal device to collect CO2 gas.
