Waste heat recovery potential in systems of integrated smelters of the ...



With the sintering plant, blast furnace, oxygen steel plant, continuous casting plant and hot rolling mill, five main plants of integrated metallurgical plants with regard to waste heat and their potential uses were investigated in this project.

Supported by interviews with the plant operators of Hüttenwerke and a plant manufacturer, the waste heat potentials of individual plants were analyzed in detail and presented in detail. Furthermore, barriers were identified that prevent a possible use of waste heat. In addition to the waste heat already in use, an additional waste heat potential of 0.322 gigajoules per tonne of crude steel (solid), which can be used for operations, was calculated - an estimated 9.45 petajoules a year.
