Description
本発明は、液体燃料と酸水素ガスの混合燃焼方法における、予混合燃焼装置に関するものである。TECHNICAL FIELD The present invention relates to a premixed combustion device in a mixed combustion method of liquid fuel and oxyhydrogen gas.
近年、石油資源の枯渇化から、酸水素ガスを利用したクリーンエネルギー利用の研究開発が行われている。しかし、液体燃料に酸水素ガスを添加して燃焼装置で燃焼する場合、気液混合するにあたり、気液混合ミキサー、ポンプ等を使用する為に酸水素ガスの混合比率が５％～８％と限度がある。In recent years, due to the depletion of petroleum resources, research and development of clean energy utilization using oxyhydrogen gas has been conducted. However, when oxyhydrogen gas is added to liquid fuel and burned in a combustion device, the mixing ratio of oxyhydrogen gas is 5% to 8% because a gas-liquid mixing mixer, pump, etc. are used to mix the gas and liquid. There are limits.
予混合燃焼装置について、特開２０１７－００２３４６号公報や特開２０１５－０４５０３２号公報のように水素、酸素混合燃焼装置が提案されている。As for the premixed combustion device, a hydrogen/oxygen mixed combustion device has been proposed as in JP-A-2017-002346 and JP-A-2015-045032.
しかし、液体燃料に酸水素ガスを添加して混合燃焼した場合、液体燃料に占める酸水素ガスの混合割合が安定して混合出来るのは気液混合ミキサー等を使用する為に５％前後であるため、気液混合燃料としては未解決な部分があった。However, when oxyhydrogen gas is added to liquid fuel and mixed combustion is performed, the mixing ratio of oxyhydrogen gas in liquid fuel can be stably mixed at around 5% due to the use of a gas-liquid mixing mixer or the like. Therefore, there was an unresolved problem as a gas-liquid mixed fuel.
本発明は、液体燃料に酸水素ガスの混合比率を自由に調整して、燃焼出来るようにし、酸水素ガスの混合比率を高め、液体燃料の燃焼効率を１００％に近ずけクリーンな燃焼をすることが課題である。The present invention freely adjusts the mixing ratio of oxyhydrogen gas to liquid fuel to enable combustion, increases the mixing ratio of oxyhydrogen gas, and brings the combustion efficiency of liquid fuel close to 100% for clean combustion. The challenge is to
本発明は上記のような点に鑑みたもので、上記の課題を解決するために、請求項１のように、予混合燃料を燃焼するバーナーノズルと液体燃料タンクとの間に酸水素ガス発生装置より供給された酸水素ガスを吸引するガス吸引口を有するインジェクターが有り、バーナーノズルとインジェクターの間に気体をナノバブル化する混合器を連接し、インジェクターのガス吸引口と酸水素ガス発生装置の間に加圧ポンプを設置し、キャビテーションを発生することなく気液混合の比率を自由に調整して、燃焼出来るようにしたことを特徴とする予混合燃焼装置。The present invention has been made in view of the above points. There is an injector with a gas suction port for sucking oxyhydrogen gas supplied from the device, and a mixer that converts the gas into nanobubbles is connected between the burner nozzle and the injector, and the gas suction port of the injector and the oxyhydrogen gas generator are connected. A premixed combustion apparatus characterized in that a pressurizing pump is installed between them so that the ratio of gas-liquid mixture can be freely adjusted without generating cavitation so that combustion can be performed.
