Abstract

The present invention is for a heat exchanger for cooling of gases having high temperature and high carbon potential as is the case by production of carbon black. Natural gas and/or oil and possible additives, such as aromatic oils and steam, are supplied to a burner (1). After the combustion the gases are brought to a heat exchanger (2). This may schematically be split up in two sections, a lower section (4) with high gas temperatures and an upper section (5) where the gas temperatures are lower. In order to make the heat exchanger tubes in the lower part of the heat exchanger closest to the inlet of the combustion gases resistant to corrosion and heat, tubes made from an alloy comprising 2-10 weight % aluminium, 10-40 weight % chromium, balance mainly iron are used.
