A stoker-type incinerator includes: a recirculated exhaust gas supply unit which allows exhaust gas resulting from treating combustion gas to reflux to a combustion gas channel (15) via a recirculated exhaust gas nozzle (36) provided on the combustion gas channel (15) and supplies the exhaust gas as recirculated exhaust gas (S3); and a secondary combustion air supply unit which supplies secondary combustion air (S2) on a downstream side of the recirculated exhaust gas nozzle (36) on the combustion gas channel (15) via a secondary combustion air nozzle (31) provided on the combustion gas channel (15), in which the recirculated exhaust gas nozzle (36) and the secondary combustion air nozzle (31) are arranged in different positions in a plan view.
