Abstract

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