In this paper

the influence factors of plume elimination are studied by numerical simulation. The results show that

under conditions with lower ambient temperature

higher environmental humidity

smaller ambient wind speed

higher flue gas velocity at the stack outlet and higher flue gas temperature at the chimney outlet

the white plume will become more obvious. Conversely

the smoke plume is reduced. The visual pollution caused by white plume

and the operation pressure as well as the operation cost of the equipment for subsequent plume treatment can be reduced by improving the coal quality

burning coal with high heat and low water content

thus to reduce the flue gas volume

the flue gas flue gas velocity and the saturated wet flue gas temperature after desulfurization.
