Zusammenfassung:	Disclosed is an apparatus for treating SO contained in a combustion gas more readily with high efficiency and at lower cost. Specifically disclosed is an exhaust gas treatment facility (100) comprising a desulfurizing agent supply unit (10), a combustion furnace (20), an exhaust gas temperature decreasing facility (30), and an electrical dust collector (40). The desulfurizing agent supply unit (10) enables the introduction of a desulfurizing agent into a position located adjacent to an upper nose section (21) in the combustion furnace (20) through a desulfurizing agent inlet (14). The facility (100) may be so adapted that an exhaust gas is supplied into the exhaust gas temperature decreasing facility (30) through a smoke path (22), a dust is removed by means of the electrical dust collector (40) while decreasing the temperature of the exhaust gas, and the dust is discharged into air through a smoke stack (49).
