Abstract
Gasification of biomass or biomass-containing streams offers a means to produce syngas that can be combusted directly or converted to higher value products. Facilities of three gasification technologies that have been put into operation have encountered issues with degradation of structural components. Our laboratory has investigated the causes of degradation of structural components of these gasifiers. In all cases, the likely causes of degradation have been determined and alternate materials identified. In some cases, these alternate materials have been put into use and found to provide improved performance. Results from examination of two types of gasifiers have been reported previously, but they are summarized in this report in order to show the parallels in materials issues for biomass gasifiers.
