The present invention relates to a duct structure of a combustion system for preventing dust particles from being accumulated, which effectively removes dust particles generated when fossil fuel is burned in equipment having a combustion system, such as a coal boiler. The duct structure of a combustion system for preventing dust particles from being accumulated comprises: a first conduit in which a discharge path where exhaust gas generated from a combustion device flows is extended in a horizontal direction; a second conduit which is extended upward from the first conduit and has an inner diameter bigger than the first conduit; a third conduit which is horizontally extended from the second conduit and has an inner diameter smaller than the second conduit; and a perforated plate which is installed inside the second conduit in a direction crossing the flow direction of the exhaust gas. |
