Abstract

In order to allow an efficient energy recovery from off-gas in the steel industry, the high variability of heat flow should be managed. A temperature smoothing device based on phase change materials is inserted into the off-gas line. To address overheating issues of the phase change material containers, a heat transfer fluid is also introduced. Performances of the smoothing system are analysed by thermo-fluid dynamics simulations and economics of the resulting energy recovery are provided.
