As the flue gas is discharged from the chimney to the atmosphere, some of the vapor water and pollutants in the flue gas will condense because of temperature drop, forming the misty water vapor at the chimney and the misty water vapor will have slight color change because of sky background color, sky illumination, observation angle and other reasons, forming the "colored plume", usually in white, grey white, blue or other colors. The plume elimination technology mainly achieves the plume elimination effects by changing the temperature and humidity of flue gas discharged from the chimney.
