| description | A system and method for purification of combustion gases cools the combustion gases to an optimal oxidation temperature, oxidizes the combustion gases, injects water or uses natural moisture content to form acid aerosols, neutralizes the acid aerosols with an alkaline solution, and then filters the acid aerosol, alkaline solution and water from the combustion gases. The purified gas stream is then exhausted from the system. Oxidation can be provided in stages to obtain optimal oxidation of different combustion gas components with different optimal oxidation temperature ranges. When used in a thermal power plant, the cooling of exhaust gases can be accomplished by regenerative preheating of combustion air, boiler feedwater or combustion fuel, and the clean exhaust gas can be cooled below the conventional exhaust stack temperature range, thus enhancing power plant efficiency. |
