Abstract
Method and apparatus for treating a gas flow including guiding the gas flow through a gas treatment unit () adapted for filtering particles in the gas flow, and eliminating the particles in the gas treatment unit (). Particles are filtered from the gas flow by means of accumulating the particles in, or in connection with, a number of ducts () forming part of the gas treatment unit () during passage of the gas flow through the gas treatment unit (). The temperature of the gas flow is controlled along the ducts () to a value that provides combustion of the particles, and eliminates the filtered particles in the gas treatment unit () by means of combustion in the ducts (). 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.
