The stack of a 600 MW power plant emitted opaque plumes after modification of the air pollution devices.To solve this problem
the flue gas components and the SCR system
which affect the opacity of the plumes most
were studied.The results show that
the concentration of SO_3 in the flue gas grew with the sulfur content in the coal
it increased significantly after the flue gas passed through the SCR denitration system
which induced visible plume.The distribution of NO_x at the SCR reactor outlet indicated the flow filed was uneven
which increased the ammonia slip and thus intensified the smoke plumes.The abrasion and inactivation of the SCR catalysts aggravated the plumes.By analyzing the factors of the plume formation
theoretical basis were provided for control of the plumes.
