A cyclone body 2 that partially burns coal internally using swirling air is attached to the side wall of the secondary furnace 1 either directly or via a connecting duct 14, and this cyclone body 2 is used to combust coal. In a cyclone coal combustion furnace provided with a gas discharge port 5 and a slag flow port 7 for guiding gas to a secondary furnace, a vertical precombustor 15 is tangentially connected to the upper end of the cyclone body 2. A coal inlet 17 is provided in the axial direction at the end of the cyclone body, a coal inlet 18 is provided in the tangential direction, and a coal inlet 18 is provided in the vicinity of the gas outlet 5 at the end of the cyclone body. A cyclone coal combustion apparatus characterized in that an input port 20 and/or a coal input port 21 are provided in the secondary furnace. 2 A cyclone body 2, which internally partially burns coal using swirling air, is attached to the side wall of the secondary furnace 1, either directly or via a connecting duct, and a gas exhaust system is attached to the cyclone body 2, which guides the combustion gas to the secondary furnace. In a cyclone coal combustion furnace provided with an outlet 5 and a slag flow outlet 7, a vertical precombustor 15a is tangentially connected to the upper end of the cyclone body 2, and the upper end of the vertical precombustor is filled with chia, air, and fuel gas. An inlet 16 and a burner 19 are provided to form a chire precombustion chamber 22 in the upper part of the vertical precombustor, and a coal inlet 23 is tangentially connected to the lower side of the chare precombustor to form a vertical precombustor. A cyclone coal combustion apparatus characterized in that a coal precombustion chamber 24 is formed below a chia precombustion chamber in a precombustor.
