Characterization of syngas produced from MSW gasification at commercial-scale ENERGOS Plants.

Characterization of the syngas produced in the gasification process has been performed at commercial-scale Energy-from-Waste plants under various conditions of lambda value and syngas temperature. The lambda value from the gasification process is here defined as the ratio of the gasification air to the total stoichiometric air for complete combustion of the fuel input. Evaluation of the syngas calorific value has been performed by three different methods, i.e., estimation of the syngas calorific value from continuous in-line process measurements by mass and energy conservation equations, measurement of the syngas composition based on gas chromatography and calculation of the Gross Calorific Value from the measured composition, and direct continuous measurement of the calorific value using based on gas calorimeter.
