The invention discloses a pulverized coal coupled combustion device and a combustion method. The device comprises a gas combustion chamber, and a pulverized coal combustion chamber arranged in the gascombustion chamber; a gas flameless combustor is mounted at the top of the gas combustion chamber; gas is combusted in a flameless mode in a cavity inside the gas combustion chamber and outside the pulverized coal combustion chamber through the gas flameless combustor; a pulverized coal flameless combustor is mounted at the top of the pulverized coal combustion chamber, and penetrates through thetop of the gas combustion chamber; and pulverized coal is combusted in a flameless mode in the pulverized coal combustion chamber through the pulverized coal flameless combustor. The pulverized coalcoupled combustion device can spontaneously maintain the pulverized coal flameless combustion with an uniform temperature field, generated by the gas flameless combustion, as an uniform radiation heatsource, and can stabilize the oxidation under a low-temperature and low-oxygen atmosphere, so that the generation quantity of nitric oxides is greatly reduced, and the ultralow emission of the nitricoxides in the pulverized coal combustion is realized.
