Learn More2021-1-5 · The first boiler pass begins at the end of the furnace, above the last secondary air injection. For regulatory reasons, a flue gas temperature of at least 850°C must be maintained for 2 seconds up to the boiler ceiling. As well here, the unprotected steel walls are exposed to high temperature corrosion.
Learn More----- • Pretreatment cools and saturates the flue gas and reduces the concentrations of corrosive chloride ions entering the absorber. Typical flue gas tem- peratures range from 290° to 310° F (145° to 155° C) before pretreatment and from 125° to 135° F (50° to 55° C) following pretreatment.1 Fly ash removal may occur in the first stage of a double-stage venturi scrubber (Figure 3).

Learn MoreThe flue gas desulfurization process could generate a large number of particulate matters (Bao et al., 2009). These aerosol particles formed during desulfurization can easily escape from the demister and enter the atmosphere. The addition of a desulfurization agent (e.g., limestone, caustic soda) could also greatly change the PM 2.5 components
