Waste Heat Recovery in Sponge Iron and DRI Plants
Waste Heat Recovery in Sponge Iron and DRI Plants Sponge iron and Direct Reduced Iron (DRI) plants operate at high temperatures and generate hot gases during the production process. These gases contain thermal energy that can potentially be recovered and used within the plant. Waste heat recovery is an important approach for improving the utilization of energy generated during industrial processes. What Is Waste Heat Recovery? Waste heat recovery involves capturing heat from hot gases or other process streams that would otherwise be released into the atmosphere. In an industrial plant, the recovered heat can be transferred to water to produce steam. Depending on the plant configuration, this steam can be used for process requirements or power generation. Waste Heat Recovery in DRI Plants DRI production involves high-temperature kiln operations. The exhaust gases leaving the process can contain considerable amounts of thermal energy. A waste heat recovery boiler can be in...
