Waste Heat Boilers for Energy Recovery In Sintering Plants

Tried-and-tested waste heat boilers for energy recovery and the use of heat from exhaust air from sinter coolers form a substantial part of the extensive Oschatz portfolio. These cool hot sintered material with ambient air. By means of the hood construction above the sinter cooler, the heated cooling air is collected and processed in a waste heat boiler to generate steam and/or hot water. The installation of an Oschatz waste heat boiler means that the significant heat being produced can be captured, saving large amounts of primary energy. Waste heat boilers for installation downstream of both sinter belts and sinter coolers with and without auxiliary firing and incorporating hot air recirculation from sinter coolers provide combustion air for auxiliary burners. If desired, it is also possible to raise the temperature level of the waste heat boiler through the installation of a gas burner. Superheated steam can then be produced for running a steam turbine.
