Abstract:Psychrometric chart analysis was used to study the wet desulfurization process of coalfired units chimney exports tend to form “white  smoke plume” reason, pointed out that at present although direct heating method is generally used  to  eliminate the  “white smoke plume”, but will increase the run of unit  energy consumption, and finally put forward by condensation and then heating process is governance “white smoke plume” effective energy saving measures.
