Abstract

The invention relates to a device for producing mechanical energy. Said device contains an internal combustion engine and an expansion engine (20, 21) which is fed with superheated steam from a steam generator. Exhaust gases of the internal combustion engine are injected into the steam generator (24) to use the waste heat thereof. In order to eliminate pollutants and non-burned fuel in the exhaust gases of the internal combustion engine in a simple and effective manner, the steam generator (24) is heated by a non-catalytic burner (16) at a burner temperature of between 1100° and 1300° C. The exhaust gases of the internal combustion engine can be combined with the combustion gases in the burner (16). The after-burning of non-burned fuel and the combustion of pollutants is thus carried out in a burner (16) in a non-catalytic manner. The combustion gases in said burner (16) are at a temperature such that non-burned fuel components in the exhaust gases of the internal combustion engine which are introduced into the burner are after-burned, but form, however, essentially no nitrogen oxides at excessive temperatures. The burner (16) is used to heat the steam generator (24) and can be des…
