The subject of the injection of ammonia in a brief description of a type of dry smoke exhaust

摘要

P in a first processing unit is stored temporarily a certain quantity of nitrogen oxides contained in the exhaust gases of combustion as a function of a numerical value representing a quantity of combustion. In a second processing unit, it is stored temporarily a mixture of ammonia and of nitrogen oxides according to a certain ratio, as a function of the temperature of the exhaust gases of combustion. A digital value observed representing the quantity of combustion is sent into the first processing unit to determine the quantity of nitrogen oxides in the exhaust gases of combustion. The temperature is observed of the exhaust gases of combustion is sent into the second processing unit to determine the ratio of the mixture, ammonia and nitrogen oxides. . The optimum quantity of injection of ammonia is obtained by multiplying the quantity of nitrogen oxides obtained by means of the first processing unit by the ratio between the ammonia and the nitrogen oxides obtained by means of the second processing unit / p
