【 摘 要 】

The method and procedure of ammonia injection optimization test in SCR denitrification unit in thermal power plant are introduced.The SCR in a 220MW unit is investigated, through ammonia injection optimization test, the distribution uniformity of NOx at SCR outlet is improved, ammonia escape concentration is reduced, then the damage of ammonia escape to boiler tail equipment is reduced, the economic and reliability of unit is improved.
