The fixed capture device (4) for the large particles is cleaned by guiding a suction nozzle (7) back and forth over its upstream side in a pendulum motion. DETAILED DESCRIPTION - A method for treating a flow of gas (A) containing particulate contaminants through a reactor comprising narrow gas channels (1) is used to prevent blockage of these channels. Large particles are selectively captured using a fixed capture device (3), which is cleaned by guiding a suction nozzle back and forth over the upstream side of the device in a pendulum motion. An INDEPENDENT CLAIM is also included for the treatment apparatus. |
