Method and apparatus for reducing the concentration of oxides of nitrogen. |
摘要 |
<p>Ammonia is introduced into hot products of combustion leaving a furnace chamber, to reduce the concentration of oxides of nitrogen. A minor proportion of the reacted gas flow is directed to a condenser (24) and the pH of the condensate is measured. The rate of addition of ammonia is controlled according to the measured pH to maintain a small excess of ammonia.</p> |
