| Zusammenfassung: | To reduce emissions of carbon dioxide while suppressing emissions of nitrogen oxide similarly as in the case where only hydrocarbon-based fuel is burned.SOLUTION: A method of controlling combustion of mixed gas obtained by mixing hydrogen gas with hydrocarbon-based fuel in a combustion facility by using a control device includes processing of: causing the control device to calculate emissions of carbon dioxide and nitrogen oxide included in exhaust gas passing through a flue of the combustion facility; causing the control device to determine an addition rate of hydrogen gas included in the mixed gas so that each of the calculated emissions of carbon dioxide and emissions of nitrogen oxide satisfies each target value; and causing the control device to control combustion of the mixed gas in accordance with the determined addition rate.SELECTED DRAWING: Figure 6
【課題】窒素酸化物の排出量を炭化水素系燃料だけを燃焼させる場合と同等に抑制しつつ、二酸化炭素の排出量を削減する。【解決手段】炭化水素系燃料に水素ガスを混合した混合ガスの燃焼設備による燃焼を、制御装置が制御する方法において、制御装置が、燃焼設備の煙道を通過する排ガスに含まれる二酸化炭素と窒素酸化物の排出量を計算する処理と、制御装置が、計算された二酸化炭素の排出量と窒素酸化物の排出量のそれぞれが各目標値を満たすように、混合ガスに含まれる水素ガスの添加率を決定する処理と、制御装置が、決定された添加率に応じ、混合ガスの燃焼を制御する処理とを設ける。【選択図】図６ |
