PURPOSE:To obtain an active-radiation irradiating apparatus, whose irradiating efficiency is excellent, by arranging a plurality of radiators on the inner wall of a tubular container, so that the main irradiation beam from each radiator in the tubular container is not directly projected on the facing radiator. CONSTITUTION:On the inner wall of a tubular container, which is surrounded by a heat iusulating material 3 in the inside of a protecting tubular outer wall 2, each radiator 5 for active radiation such as infrared rays is held by each holder 6. A plurality of the radiators are arranged in the same horizontal zone. In a zone under said horizontal zone, a plurality of radiators 5' are attached to the inner wall by holders 6' so that the radiators 5 and 5' are alternately arranged. Spacers 8 are arranged only at one side of the bottoms of the holders 6 and 6'. The radiators are inclined so that the main irradiation of each of the radiators 5 and 5' is not directly projected on each of facing radiators 5 and 5'. Thus, an active-radiation irradiating device, whose irradiation efficiency is excellent, is obtained. |
