Abstrakti

Selective Non-Catalytic NO_x reduction based on ammonia injection has been tested in a 2000 tds/d recovery boiler. The results showed good reduction rates with limited ammonia slip over the load range 60-100%. For the other emissions, ammonia addition had no or minor impact. Special attention was paid to the ash chemistry to evaluate the potential for ammonium salt formation on the heating surfaces. Analyses of deposit samples together with thermodynamic equilibrium calculations show that this potential is limited and will not affect the deposit characteristics.
