The invention relates to a system for producing energy from conventional waste utilization, consisting of: a combustion chamber (1) having a combustion grate; an exhaust gas cleaning system (3); an evaporator (2, 9, 13, 14); a steam drum (10, 15, 16); a steam turbine (4); a generator (12); a condenser (12); a flue (19); and lines, wherein: the steam generator (9) consists at least of a low-pressure (LP) evaporator (13) and a high-pressure (HP) evaporator (14) and each evaporator (13, 14) is assigned a steam drum (15, 16) and a separate condenser (17.1, 17.2); and the condensers (17.1, 17.2) couple the evaporators (13, 14) to an ORC turbine (28). The invention further relates to a method for producing energy. The system according to the invention and the method according to the invention combine, in a conventional waste incineration system (waste incineration system), a conventional steam boiler with an ORC process, with the advantage that the corrosion caused by exhaust gases at the steam boiler is minimized by means of a special heating surface circuit, high efficiency being achievable at the same time.
