摘要： 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 via a recirculated exhaust gas nozzle provided on the combustion gas channel and supplies the exhaust gas as recirculated exhaust gas. The stoker-type incinerator further includes a secondary combustion air supply unit which supplies secondary combustion air on a downstream side of the recirculated exhaust gas nozzle on the combustion gas channel via a secondary combustion air nozzle provided on the combustion gas channel, in which the recirculated exhaust gas nozzle and the secondary combustion air nozzle are arranged in different positions in a plan view.
