ABSTRACT:
A process and installation for preheating scrap containing organic matter, in which flue gas is afterburned in an afterburner combustion chamber at a temperature at more than 1200.degree. C. The after-burned hot flue gases are guided, without being cleaned, via a heat exchanger. Fresh intake air is heated in the heat exchanger by sensible heat of the after-burned hot flue gases. A first portion of the heated intake air at a temperature above an ignition temperature of organic matter is guided in adjustable amounts through at least one basket filled with scrap. Another portion of the heated air exiting the heat exchanger is made available in adjustable quantities to the afterburner as hot blast and/or mixed in the another portion of heated intake air with the after-burned hot flue gases.
