The invention discloses a fuel and air mixing device for a low-pollution burning chamber of a gas turbine. Fuel comprises a main burning level and a duty burning level; and air is supplied by a three-stage cyclone. The fuel and air mixing device is characterized in that the central duty level adopts diffusive burning, and the peripheral main burning level adopts premixing or semi-premixing burning. The central duty level consists of a centrifugal atomizing nozzle and first-stage cyclone air; and the rotating directions of the first-stage cyclone air and second-stage cyclone air are opposite. The fuel of the main burning level is supplied by a multipoint direct-injection type nozzle, the air is respectively supplied by the second-stage cyclone air and third-stage cyclone air, and the rotating directions of the second-stage cyclone air and third-stage cyclone air are opposite.
