A full-mixing overfire air device of a W-shaped flame boiler relates to an overfire air device of a boiler. The invention aims to solve the problems of the prior W-shaped flame boiler adopting overfire air nozzles in direct flow structure form, such as higher carbon content in fly ash resulting from the fact that the gas and pulverized coal in the jet flow of the conventional boiler are unlikely to be mixed with those between adjacent jet flows due to the poor lateral diffusion capacity. The higher carbon content in the ash can lower the heat efficiency of the boiler and increase coal consumption of power plants. One end of an outer air channel of the overfire air device is fixed on the outer side wall of an upper furnace at an overfire air nozzle, wherein the overfire air accounts for 25to 30% of the total amount of air fed into the boiler. The overfire air is divided into two portions when entering the overfire air channel, one portion enters an inner air channel and is ejected to the furnace to achieve higher momentum, and the other portion enters the outer air channel to achieve higher rotation intensity, so that the two portions of the overfire air can achieve higher lateraldiffusion capacity when entering the upper furnace and can be mixed with gas between two adjacent portions of the overfire air jet flow.
