Experimental Study of a Downdraft Char Gasifier: Variation of Temperature and Gas Concentration in the Radial and Longitudinal Directions

A. De Paula-Oliveira, J. Brammer & L. Van De Steene
Biomass gasification is considered today as a promising route for energy production, including electricity, natural gas or synthetic biofuels. Mechanisms involved in such processes are very complex and need further understanding. In downdraft gasification processes, the gasification zone containing carbon residues (char) is fundamental to the energy efficiency and the quality of gas produced. This work provides the necessary data for validation of 2D CFD codes to investigate the behaviour of the gasification zone of...
