<p>In an energy-producing installation comprising a diesel engine (12), a steam generator (13) and a combustion chamber assembly (11) which is connected between the exhaust discharge system of the diesel engine and the steam generator for heating the engine exhaust gases by means of an oil burner (15) utilizing the oxygen of the exhaust gases, the combustion chamber assembly has an exhaust gas intake (14) subdivided into a plurality of intake passageways (21, 25, 29, 32) arranged in parallel-flow relation. Of these, two intake passageways (21, 25) supply exhaust gases serving as primary and secondary combustion air and a further one (29) supplies exhaust gases to a cooling passage (27) which surrounds a first mixing chamber (24) for combustion gases and opens into a second mixing chamber (30) which also receives the combustion gases from the first mixing chamber (24) and exhaust gases supplied through a still further intake passageway (32). The volume flow rate in the cooling passage (27) is kept substantially constant, regardless of the total volume flow rate of the exhaust gases.</p> |
