Burner And Method For The Regeneration Of Filtration Cartridges And Devices Equipped With Such Burner

A method for heating at least one filter cartridge for the exhaust gases of an internal combustion engine at a temperature above the oxidation temperature and/or the combustion temperature of the solid particulates trapped in the filter cartridge, by means of a burner comprising a burner body having a symmetry of revolution, the burner body having a closed end and having on the side opposite the closed end a discharge opening suitable for connection to a duct for removing the exhaust gases;

• said method consisting of:
• injecting, in a direction essentially tangential to the burner body, a mixture of fuel and oxidiser, so as to apply a swirl motion to the mixture inside the burner body;
• supplying electricity to an electrical ignition means positioned inside the burner body, in order to ignite the mixture, the burner body comprising a closure element obstructing a substantial portion of the burner body, so as to limit the turbulence that may be generated by the exhaust gases on fluid flows within the volume of the burner body bounded by the closure element;
• interrupting the mixture injection after the oxidation temperature and/or the combustion temperature has(have) been reached during a period depending on parameters such as a load withstood by the engine and a pressure drop due to a clogging of the filter medium by these solid particulates.
