Abstract: A process for the production, treatment and combustion of synthesis gas for the purpose of generating electric power is disclosed. The synthesis gas is produced from a solid, carbon-containing fuel with the aid of an oxygen-containing gas and treated by a slag-separating device and a device separating alkalis. Subsequently, the synthesis gas produced is fed to an expansion turbine where the pressure energy is used for generating power. On account of the treatment and separation of alkalis the expansion turbine is protected from corrosion and mechanical impact. The expanded synthesis gas is then burnt under pressure and the combustion is used in a combined-cycle process using a gas turbine, steam generator and steam turbine for generating power. The process thus has an increased efficiency. Apparatus for use of the process is also described.

Abstract: A process for the production of synthesis gas by gasification with the aid of air or oxygen or oxygen-saturated air as well as water vapor, a solid or liquid carbon-bearing fuel material being fed to a reactor, is shown. The fuel material is converted with the aid of air or oxygen or oxygen-saturated air and water vapor at an elevated temperature into a synthesis gas essentially consisting of hydrogen, carbon dioxide and carbon monoxide; the reaction also yields mineral slag droplets which are removed from the reactor separately from the synthesis gas obtained, and the synthesis gas being discharged from the reactor in any random direction desired; the vaporous alkalis contained in the synthesis gas come into contact with a getter ceramic material so that they separate from the synthesis gas and hence, the synthesis gas can be sent to a slag separation device without previous cooling step and the slag droplets being withdrawn from the said device as liquid slag.
