Abstract

PURPOSE: To maintain a good rate of denitration stably over a long period of time and, at the same time, to facilitate the maintenance and control of the nozzles for injecting NH3, by installing the injection nozzles of which on the outer circumferential part the corrosionresisting and heat-shielding means has been applied in a specified high temperature range of the exhaust gas containing NOx and by feeding NH3 spraying through these nozzles.
