EXHAUST GAS CLEANING APPARATUS AND METHOD FOR CLEANING AN EXHAUST GAS

摘要

There is described an exhaust gas cleaning apparatus for the cleaning of exhaust gas which originates from a combustion process in a combustion chamber. The exhaust gas cleaning apparatus comprises an exhaust gas flow path which is arranged in fluid communication with the combustion chamber and through which the exhaust gas is flowing, and a cold flame gas supply which provides a cold flame gas. The cold flame gas supply is arranged in fluid communication with the exhaust gas flow path such that the cold flame gas can be injected into the exhaust gas flowing in the exhaust gas flow path and thereby, at least partly, remove impurities such as particulate matter, NOx and hydrocarbons, which are present in the exhaust gas. There is also described a method for cleaning of exhaust gas.
