Abstract: Disclosed is a gas conditioner and a method for treating crude, relatively impure gases produced from a gasification process to yield a relatively clean, tar-free producer gas having an energy value of about 1200 to 1500 Kcal/m.sup.3. The gas conditioner comprises a reaction chamber for retaining a fuel supply and containing a cracking reaction. An upper portion of the reaction chamber includes an internal reaction housing which provides a primary reaction zone. The gas conditioner also includes a grate structure for filtering producer gas prior to its exit from the conditioner.
