# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for iron and steel production (notified under document C(2012) 903) (Text with EEA relevance) (2012/135/EU), Division: Description

Extent: E+W+S+N.I.

Two kinds of potentially reusable waste energies are discharged from the sinter plants:
the sensible heat from the waste gases from the sintering machines
the sensible heat of the cooling air from the sinter cooler.
Partial waste gas recirculation is a special case of heat recovery from waste gases from sintering machines and is dealt with in BAT 23. The sensible heat is transferred directly back to the sinter bed by the hot recirculated gases. At the time of writing (2010), this is the only practical method of recovering heat from the waste gases.
The sensible heat in the hot air from the sinter cooler can be recovered by one or more of the following ways:
steam generation in a waste heat boiler for use in the iron and steel works
hot water generation for district heating
preheating combustion air in the ignition hood of the sinter plant
preheating the sinter raw mix
use of the sinter cooler gases in a waste gas recirculation system.
