This invention relates to a gas reburning and double-channel rich/lean integrated combustor of low Nox, in which 7 air nozzles and 7 fuel nozzles interlace with each other. The air nozzles are all connected to a bellow and receive air supply from a large tank-type bellow. The fuel nozzles are connected to respective fuel system through the bellow. From up to down, the 7 fuel nozzles are: the gas nozzle, the double-channel up-lean and down-rich coal powder nozzle, the double channel up-rich and down-lean coal powder channel, 3 double-channel level rich/lean coal powder nozzle (the rich phase is near the flame), and the oil nozzle inside the nethermost air nozzle.
