Gasification Gaseous Product and Oxidizing Atmosphere

Gasification proceeds under higher temperatures (above 900°C) than pyrolysis and often under oxidizing conditions. It is essentially a two- or three-step incineration. An Italian pilot plant [42] has the following operating parameters  

Input per hour 4200 kg of MSW, compacted and degassed Output per kilogram charged  

The compacted waste is pyrolyzed at 600°C and then fed to a gasifier at 2000°C and pressures of 20-65 bar. The syngas after cleaning is used to drive a gas turbine producing 300 kW of electricity.
