A mathematical model of a rotary kiln oxy-pyrolyzer of sewage sludge is presented. The specific feature of the model is the axial staging of O2 feeding to the reactor as one important key to the quality of the syngas. The steady operation of the oxy-pyrolyzer is analyzed in terms of fluxes of the solid fuel and of the gaseous species, temperature of the solid and of the gas phases along the reactor. The performance of the reactor is characterized in terms of process rate and chemical composition of the produced syngas, heating value and thermal power.

Abstract
A mathematical model of a rotary kiln oxy-pyrolyzer of sewage sludge is presented. The specific feature of the model is the axial staging of O2 feeding to the reactor as one important key to the quality of the syngas. The steady operation of the oxy-pyrolyzer is analyzed in terms of fluxes of the solid fuel and of the gaseous species, temperature of the solid and of the gas phases along the reactor. The performance of the reactor is characterized in terms of process rate and chemical composition of the produced syngas, heating value and thermal power.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
