Description

ak Attorney Patents Specification in or relating to gas burners Allan a subject of do y declare the of this and in what same is to he to described in and by following this relates to an gas for internal combustion evacuating the like for the combustion of inter a hy rocarbons and carbon which occur in the exhaust by reason of in engine or of invention its to provide an exhaust burner which can function continuously without particular heat source being clogged by solid articles accompanying the exhaust and can be at low costs to enable extensive for instance motor invention provides an exhaust gas burner comprising an elongated combustion chamber which is for connection in an exhaust gas conduit to permit exhaust gases to flow therethrough which for this has an exhaust gas inlet and an exhaust gas outlet and is with an inlet for air into the and an insert of catalysing material in the combustion chamber for continuous ignition of combustible components occuring in the said insert being adapted to be kept by combustion in the For better elucidation the invention will described in detail in the following with reference to drawings in 1 is an axial section of an the exhaust gas burner according to the intended for use with motor 66 is an axial section of another embodiment of the exhaust gas burner according to the likewise intended for with motor vehiclesj 66 4 is an axial section o a of gas burner to for use with motor 66 exhaust in 1 comprises a combustion chamber of shape o by fireproof iron or sheet An exhaust gas inlet pipe 11 is at of the for air through injector action by gas of the engine there is arranged with gas 11 with the on pipe there is arranged a further pipe for air by of a fan the supplied air been heated in the water or air cooling of the engine

the pi is an 17 which has an internal conical surface which s towards the interior of the combustion This likewise adjustable longitudinally of the to prevent shocks in the combustion ehassbor being transferred against the direction of the exhaust into the and This action be improved in that the is neck portion surrounds the pipe 12 leaving an annular space to pipe By this the air entering the combustion chamber 10 through the 12 excerts an injector action upon the air in the and injector action may be so pronounced that a specific fan or the like for supplying air through the pipe 13 possibly dispensed As the together with the neck portion the turbulator are adjustable of the combustion 10 the same combustion chamber is easily adjustable to different engine A socket 19 is provided at the other of the cha ber for the connection of the exhaust gas burner to an outlet For Maintaining the combustion in the chamber after the latter has reached a certain a of without the intermediary
