Burning diesel oil with little excess oxygen may be performed while limiting the maximum temperature in one single step by means of a method, which according to the invention comprises feeding back of a very large part of the exhaust gases to the combustion zone after they have released part of their heat contents, but before they have left the combustion apparatus. The invention also relates to a device for working the method. This comprises a fuel injection device 1, at least one introduction duct 3 directed towards this for gas containing oxygen, and an exhaust duct 2, 8, 11 containing a heat exchanger 4, 5 cooling the exhaust gases. A channel 12 for introduction of pure oxygen gas opens into an introduction duct 3 and corresponds with the exhaust duct 11 downstreams of the heat exchanger 4, 5 in such a way that the pure oxygen gas is mixed with the cooled exhaust gases by ejector action. <IMAGE> |
