Method and apparatus for treating a gas flow including guiding the gas flow through a gas treatment unit ( 18 ) adapted for filtering particles in the gas flow, and eliminating the particles in the gas treatment unit ( 18 ). Particles are filtered from the gas flow by means of accumulating the particles in, or in connection with, a number of ducts ( 21 ) forming part of the gas treatment unit ( 21 ) during passage of the gas flow through the gas treatment unit ( 18 ). The temperature of the gas flow is controlled along the ducts ( 21 ) to a value that provides combustion of the particles, and eliminates the filtered particles in the gas treatment unit ( 18 ) by means of combustion in the ducts ( 21 ). An improved treatment of a gas flow is provided, in particular in connection with exhaust gas purification in a diesel engine, for eliminating particles in its exhaust gases. |
