The invention provides a uniform continuous feeding device for garbage incineration fly ash particles. The uniform continuous feeding device comprises a fluidized bed feeder. The fluidized bed feederis provided with a wind inlet and a material storing bin. A tail outlet of the fluidized bed feeder is connected with an inlet of a cyclone material separator. The upper portion of the cyclone material separator is connected to the upper portion of a high-temperature melting furnace through a wind pipe. A solid particle collector is arranged on the bottom of the cyclone material separator. The solid particle collector is connected with a preheating furnace. The connecting position is arranged on the upper portion of the preheating furnace. The preheating furnace is located above the high-temperature melting furnace and communicates with the high-temperature melting furnace. An oxygen inlet and a molten slag outlet are formed in the bottom of the high-temperature melting furnace. Accordingto the uniform continuous feeding device, by means of the coordinative effect of the fluidized bed feeder and the cyclone material separator, continuous uniform feeding of materials is achieved.
