Zusammenfassung:	To provide a boiler control device capable of estimating a fuel heating amount to stably operating a boiler, a boiler, a boiler control method, and a boiler control program.SOLUTION: A boiler control device 50 for controlling a boiler, comprises a state quantity acquisition unit 51 that acquires a state quantity of the boiler, and a calculation unit 52 that calculates a fuel calorific value, which is a heating value of fuel input to the boiler, based on the state quantity of the boiler and boiler efficiency that is preset in the boiler control device 50. When a fluctuation amount in the fuel calorific value calculated by the calculation unit 52 satisfies a predetermined condition, the fuel calorific value is used to perform control to correct a fuel flow rate input to the boiler.SELECTED DRAWING: Figure 4 【課題】燃料発熱量を推定しボイラを安定稼働させるボイラ制御装置、ボイラ、ボイラ制御方法およびボイラ制御プログラムを提供する。【解決手段】ボイラの制御を行うボイラ制御装置５０であって、ボイラの状態量を取得する状態量取得部５１と、ボイラの状態量及びボイラ制御装置５０に予め設定されたボイラ効率に基づき、ボイラに投入される燃料の発熱量である燃料発熱量を算出する算出部５２と、を備え、算出部５２によって算出された燃料発熱量の変動量が所定の条件を満たす場合に、燃料発熱量を用いてボイラに投入される燃料流量を補正する制御を行う。【選択図】図４
