Abstract
A process and a reactor for the of a carbonaceous feed. The reactor has a reactor chamber; steam generating heat exchange units; at least one steam drum; and recirculation lines for circulating water and steam between one or more of the heat exchange units and the steam drum. The steam drum further includes a steam feed line for transporting steam via a heat exchange unit and a superheated steam line to a superheated steam header. The superheated steam line is split into a return line leading to a heat exchange line through the steam drum, and a header feed line.

A gasification reactor comprising:
- a reactor chamber;
- steam generating heat exchange units;
- at least one steam drum;
- recirculation lines for circulating water and steam between one or more of the heat exchange units and the steam drum
- wherein the steam drum further comprises a steam feed line for transporting steam via a heat exchange unit and a superheated steam line to a superheated steam header, wherein the superheated steam line is split into a return line leading to a heat exchange line through the steam drum, and a header feed line, wherein the reactor comprises one or more valves for selectively opening or closing the return line or the header feed line wherein the heat exchange line through the steam drum is connected to a secondary superheated steam feed line leading to the superheated steam header and wherein the secondary superheated steam feed line joins the header feed line before opening into the superheated steam header.
