Disclosed is a method for generating power from exhaust heat by effectively using the heat emitted from an incinerator. The method for generating power from exhaust heat includes: a first heat exchange step, in which hot air (2) heated by the exhaust gas from the incinerator (101) of a sewage treatment system (S) is supplied to a superheater (19), which is provided to the power generation system (G) at a position upstream from a turbine (10) and downstream from a separator (18), and undergoes heat exchange with a working liquid (L); a second heat exchange step, in which the hot air (2) is supplied to a heater (17) located upstream from the separator (18) and undergoes heat exchange with the working liquid (L); a waste water heat exchange step, in which the hot air (2) from the heater (17) undergoes heat exchange with the waste scrubbing water (W) emitted from the sewage treatment system (S) after scrubbing the exhaust gas; a third heat exchange step, in which the waste scrubbing water (W) is supplied to a vaporizer (16) upstream from the heater (17) and undergoes heat exchange with the working liquid (L); and a contact step when the hot air (2) comes into contact with the exhaust gas. |
