A plasma burner (100) and a diesel particulate filter (DPF) trap (80) that can effectively oxidize and remove a particulate material (PM) within an exhaust gas by preheating fuel and mixing the fuel with the exhaust gas are provided. The DPF (80) includes: a filter that is connected to an exhaust conduit at a side opposite to that of an engine (20); a plasma burner (100) that is provided within the exhaust conduit between the engine (20) and the filter (80), and that includes a fuel inlet (122) that supplies fuel and a flame vent (128) that projects a flame by a plasma discharge, and that heats exhaust gas; and a fuel inflow conduit (112) that connects the fuel inlet (122) and a fuel tank (30). |
