1/5/2016, · After the desulfurization wastewater is injected into the flue gas, flue gas humidity increases from 7.14% to 7.56% together with the decrease of flue gas temperature from 142 °C to 136 °C. The flue gas is unsaturated under the conditions, and the flue gas temperature is higher than the acid dew point, thus the flue duct and electrostatic precipitator will not be corroded.
