The oxidization zone temperature in an updraft gasifier is usually sufficiently high to cause slagging of the ash. Exhaust gas recirculation (EGR) was tested and shown to effectively reduce grate temperatures for updraft gasification of woodchips and to have no significant effect on system efficiency. A simple damper controlled EGR duct design was found to provide uniform grate temperature over a wide range of gasification rates in the fan motivated system.
