The invention discloses a method and equipment for reburning combustible solid particles. The equipment comprises devices such as a gas storage tank, an ash storage bin, a delivery pump, an ash bin and a hot-blast stove and further comprises connecting pipelines and valves. The connecting pipelines and the valves are arranged between the devices. The method includes steps of collecting the combustible solid particles; conveying the combustible solid particles and starting the equipment; delivering inlet delivered gas; separating the combustible solid particles from the delivered gas; reburning the combustible solid particles and the like. The delivered gas is non-combustion-supporting single-component gas or mixed gas. The method and the equipment have the advantages that particulate matters can be efficiently conveyed, the running cost can be reduced, and the method and the equipment are high in safety.
