Coal boiler flue gases contain many impurities which are highly detrimental to an amine-based liquid absorbent. Flue gas pretreatment is needed, which generally consists of two sections: one dedicated to NO2 and SO 2 removal, and one dedicated to flue gas water saturation and cooling to 3040°C.

Coal-burning Flue Gas Wet Scrubber For Boiler

01/06/2017 · The content of water vapor in the flue gas of coal-fired power plant is 1216% ; the main source of moisture in flue gas mainly comes from coal combustion and wet desulfurization system. In addition, flue gas denitrification systems and wet dust collector can also increase humidity of flue gas, but the amount of water is much lesser than that produced by coal and wet FGD system.

the water is in alkaline side. Atomized water droplets are collected easily on electrodes by electrostatic force because of their larger diameter compared with particulate matters contained in the flue gas, and they form water film flow on the collecting electrodes. Particulate matters collected by electrostatic force are captured in this water
