ABSTRACT:
The process for cooling of partial oxidation crude gas includes partially oxidizing a fine grained to powdery combustible material in a flow gasifier in the presence of water vapor and an oxidizing member selected from the group consisting of oxygen and air at pressures of up to 100 bar and at temperatures above a cinder melting point to form a crude gas flow; feeding the crude gas flow in a crude gas duct in an upward crude gas flow direction; and feeding an annular cooling flow of a gaseous or vaporous cooling fluid into the crude gas flow in a downward direction opposite to the crude gas flow direction, the annular cooling flow being bounded by interior walls of the crude gas duct. In a preferred embodiment the annular cooling flow is fed into an upper quenching chamber having a diameter smaller than a downstream connected lower quenching chamber through which the crude gas flows so as to prevent upward extension of any growing cinder layer.
