Air‐blown auto‐thermal bubbling fluidized bed gasification of refuse derived fuel (RDF) and wood pellet mixtures was investigated at 725 °C, 800 °C, and 875 °C. Gasification of mixtures containing RDF at 875 °C resulted in agglomeration of bed material, which prevented steady state operation of the gasifier. Results from the analysis of produced gases, equivalence ratios, and feed rates, did not indicate significant interactions between the two different types of fuel pellets during gasification. RDF was found to yield more tar than wood pellets, but wood pellets tended to produce more problematic tar compounds. Only small variations in the lower heating value of produced gases were observed, though a greater portion of the heating value of the gases produced with RDF was provided by C 2 and C 3 hydrocarbons.
