Practice of Sintering Waste Heat Recovery of Baosteel
Sintering,as one of the most important processes before iron making,is rich in waste heat resources,and there is much room for reducing energy consumption.On the basis of summarizing the main energy-saving technologies of sintering,such as ultra-high bed sintering technology,hot-air sintering technology and flue gas circulation technology,in view of the current operation status and the problems of the sintering machine,the company has implemented ultra-high bed modification,added hot-air sintering,modified the liquid-sealed circular cooler into a rotary-arm type circular cooler,modified a floor-standing type of waste heat boiler into a direct-connected hood type of waste heat boiler,and carried out frequency conversion modification on the main exhaust fan.The renovation has significantly improved the efficiency of energy utilization,so that the energy consumption of the process has reached the domestic advanced level.
