PURPOSE:To obtain a satisfactory diffusing and mixing condition of fuel gas with combustion air of the title combustion device and to secure a good combustion state of short flame length causing low fuel loss by disposing plural numbers of fuel pipe and plural numbers of air ejecting port separately but adjacent to each other. CONSTITUTION:Combustion air 201 is introduced into an air chamber B, then town gas is fed to a pilot burner 41 and ignited by generating spark from a discharge electrode 404, and ignition is confirmed by a flame current value of the pilot flame 403 with a sensing electrode 405 for the pilot flame. Thereafter, preheating fuel 101 introduced into a fuel chamber A is ejected through plural fuel pipes 110 disposed to a perforated plate 211, and mixed with combustion air ejected from plural air injection holes 210 scattered adjacently to the fuel pipes 110. The fuel/air mixture is ignited with a pilot 403 forming thus burning flame 102, and a reforming furnace is preheated with the burning flame, and the preheating combustion is ceased thereafter. Then, a mixture of feed gas with H2O is introduced into a reforming reaction pipe 903, and generation of electric power is commenced by introducing H2-enriched reformed gas into a generating cell 902. |
