Description
即ちエンジンの回転数を上げるために供給する燃料を多くすると、それだけ不完全燃焼として排出される軽量炭化水素の量が増える。特許文献2では水素ガスの供給量をどのようにコントロールするかについての開示がない。
したがって、本願発明による運転方法は実際の運転に則した方法と言える。
ガスエンジン(ディーゼルエンジン)1とLNGなどの燃料ガスタンク2との間には、ガス燃料を供給する供給ライン3が設けられている。
この実施例では、必要最小限の水素量で、ガスエンジンにおける燃料ガスの不完全燃焼を解決する自動制御方法を示す。水素の爆発限界は空気量に対する割合で決まる。すなわち、単位時間にエンジンに取り込まれる空気量と同じ時間で投入される水素量の比が限界値以下で燃料ガスを完全燃焼させる最少の水素量と成るよう自動制御するものである。このシステムの構成は、エンジンの排ガス中の未燃ガス分を測定する検出器と、この値に基づき、効果のある最少水素量を求める制御器、および、制御器からの指令に基づき水素ガスをエンジンに送る供給装置である。
Claims (1)
- 天然ガス、バイオガス、石炭ガス、プロデューサーガスなどのガス燃料を使用するエンジンへの水素ガス供給装置であって、この装置は前記エンジンの排ガス中の未燃ガス分を測定する検出器と、前記ガス燃料中への水素ガスの供給を調整する調整バルブと、前記検出器および調整バルブを制御する制御装置を備え、前記検出器からの信号が制御装置に送られ、この制御装置から前記調整バルブに、エンジンの未燃ガス分に対応し且つ供給されるガス燃料に対する割合が爆発限界以下となる量の水素を供給する開度となる信号が送られることを特徴とする水素ガスの供給装置。
