Results of experimental and theoretical investigations of a sewage sludge gasification process have been presented. They show that higher oxygen content in sewage sludge causes a reduction in the reaction temperature. As expected, increasing the air flow rate caused a decrease in the heating value of the produced gas. A higher amount of oxidizer increases the amounts of noncombustible species and volumetric fraction of nitrogen, thus reducing the heating value of the obtained gas. Higher water content in the sewage sludge affects the gasification gas composition. As a result, combustible components are in the minority in the syngas.
