To appropriately estimate a fuel supply state in a combustion furnace.SOLUTION: A state estimation device for a combustion furnace comprises: a model acquisition unit constituted so as to acquire a first model using a plurality of time-series furnace interior image data indicating a combustion state in the combustion furnace over a first period as an input, and a second model using a plurality of time-series measurement values of one or more state quantities indicating a state in the combustion furnace over a second period longer than the first period as an input; a first output calculation unit constituted so as to calculate a first output by using the plurality of furnace interior image data and the first model; a second output calculation unit constituted so as to calculate a second output by using the plurality of measurement values and the second model; and a score calculation unit for calculating a score indicating a fuel supply state in the combustion furnace on the basis of the first output and the second output.SELECTED DRAWING: Figure 2 【課題】燃焼炉における燃料供給状態を適切に推定する。【解決手段】燃焼炉の状態推定装置は、第１期間にわたる燃焼炉内の燃焼状態を示す時系列の複数の炉内画像データを入力とする第１モデル、及び、前記第１期間よりも長い第２期間にわたる前記燃焼炉内の状態を示す１以上の状態量の時系列の複数の計測値を入力とする第２モデルを取得するように構成されたモデル取得部と、前記複数の炉内画像データ、及び、前記第１モデルを用いて、第１出力を算出するように構成された第１出力算出部と、前記複数の計測値、及び、前記第２モデルを用いて、第２出力を算出するように構成された第２出力算出部と、前記第１出力及び前記第２出力に基づいて、前記燃焼炉における燃料供給状態を示すスコアを算出するスコア算出部と、を備える。【選択図】 図２
