Zusammenfassung:	To provide a boiler control system capable of improving energy efficiency.SOLUTION: A boiler control system comprises: a boiler group including plural boilers; and a control device storing plural combustion patterns prescribing the respective operation loads of the plural boilers per total load of the boiler group to control the operation loads of the boilers based on the combustion patterns. In the plural combustion patterns, the operation numbers of the boilers prescribed in at least a part of the total load are mutually different. The control device derives the average load of the boiler group in a predetermined period, determines one of the plural combustion patterns based on the derived average load, and determines the respective operation loads of the plural boilers based on the determined combustion pattern and the total load.SELECTED DRAWING: Figure 7 【課題】エネルギー効率を向上させることができるボイラ制御システムを提供する。【解決手段】複数台のボイラを含むボイラ群と、複数台のボイラそれぞれの運転負荷をボイラ群の合計負荷ごとに規定する複数の燃焼パターンが記憶され、燃焼パターンに基づいてボイラの運転負荷を制御する制御装置と、を備える。複数の燃焼パターンは、少なくとも一部の合計負荷に規定されるボイラの稼働台数が互いに異なる。制御装置は、予め定められた期間におけるボイラ群の平均負荷を導出し、導出された平均負荷に基づいて、複数の燃焼パターンの中からいずれかを決定し、決定された燃焼パターンと合計負荷とに基づいて、複数台のボイラそれぞれの運転負荷を決定する。【選択図】図７
