Abstract

A process for treating steam-saturated crude gases from an entrained flow gasification of fuels before entry into heat exchangers sited upstream of a crude gas converting operation. To avoid solid deposits in an entrance region of the heat exchangers, the crude gas is converted from a saturated into a superheated state by supply of a hot gas to the crude gas. Hot gas contemplated is superheated high pressure steam or recycled superheated converted crude gas.
