| Abstract: | A multi-burner-port annular flameless ceramic burner (MAFCB) of the shaftless stove for blast furnaces was designed. The characteristics of pressure drop, homogeneousness of the flows at burner ports, and distribution of the flows in the chambers and joint were studied by cold model experiments. This type of ceramic burner was successfully applied in 6# blast furnace at Liuzhou Iron & Steel Co. Ltd. (LISC) and this practice proved that it could be used in the hot blast stove and other stoves with a higher efficiency and a higher steadiness of hot blast temperature at 1200°C. With the combustion of blast furnace gas alone, the thermal efficiency was up to 78.95%, saving energy remarkably. |
