To provide a combustion control method and a combustion control device of a stoker incinerator which adjust a primary air quantity and an oxygen quantity adapted to a temperature state of a combustion surface by highly accurately detecting a combustion surface temperature of a combustibles layer by removing influence of 'trailing' of a combustion flame, prevent the occurrence of inconvenience such as damage and transport impossibility of an ash sintering and ash processing unit, and also adjust an enriched oxygen supply quantity by quickly following a movement of a burn-off point.
This stoker incinerator performs: primary combustion including gasification by supplying primary air from a primary air pipe with a primary air flow regulating valve in the combustibles layer of a combustion furnace; and secondary combustion by supplying secondary air to a secondary combustion chamber. The incinerator also supplies oxygen in the combustibles layer on the combustion furnace via an oxygen supply pipe opened and closed by an oxygen flow regulating valve, detects a surface temperature of combustibles in the combustion furnace by removing influence of the combustion flame, and adjusts: a supply quantity of the primary air via the primary air flow regulating valve on the basis of a detecting valve of the surface temperature; and a supply quantity of oxygen via the oxygen flow regulating valve.
