Combined combustion and exhaust gas cleansing plant

Abstract

A combined combustion and exhaust gas filter plant including a combustion chamber (5) for pressurized combustion of combustible substances, a supply device (3, 8) for supplying up to 100 percent oxygen enriched combustion air to the combustion chamber (5), and a scrubber (10, 12) for pressurized cooling and washing with water of exhaust gases produced by the combustion chamber (5). The scrubber (10, 12) separates environmentally endangering materials and other contaminants from the exhaust gases and includes a deducting device for deducting the washing water and the environmentally endangering materials and other contaminants captured, dissolved or condensed in the washing water. An expansion device (14, 20) is coupled to the scrubber (10, 12) and expands remaining exhaust gases in one or more steps such that a sufficiently low temperature is achieved at an output of the expansion device (14, 20) for condensing remaining environmentally endangering materials and other contaminants contained in the remaining exhaust gases. A separating device (16, 22) is coupled to the expansion device (13, 20) for separating the condensed remaining environmentally endangering materials and other contaminants from the remaining exhaust gases and for collecting the condensed remaining environmentally endangering materials and other contaminants in solid or liquid form. A pump (27) is coupled to the separating device (22) for sucking out the remaining exhaust gases from the separating device (22) at a predetermined pressure close to 0 bar.
