Abstract
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。 The present invention relates to a premixed combustion apparatus 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、回転式ポンプ例えば過流ポンプ、ギヤーポンプ等を使用する為にキャビテーションを起こし酸水素ガスの混合比率が４％〜７％と限度がある。 In recent years, due to the depletion of petroleum resources, research and development on the use of clean energy using oxyhydrogen gas has been carried out. However, when oxyhydrogen gas is added to liquid fuel and burned in a combustion device, cavitation occurs due to the use of a rotary pump such as a turbulent pump or gear pump when gas-liquid mixing is performed, and the mixing ratio of oxyhydrogen gas is increased. There is a limit of 4% to 7%.
予混合燃焼装置について、特開２００７−１３９４０５号公報や特開２０１７−１２２５４０号公報のように水素混合燃焼装置が提案されている。 As for the premixed combustion device, hydrogen mixed combustion devices have been proposed as in JP-A-2007-139405 and JP-A-2017-122540.
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過流ポンプ等を使用しても４％〜７％前後であるため、気液混合燃焼装置としては未解決な部分があった。 However, when oxyhydrogen gas is added to the liquid fuel and mixed combustion is performed, the mixing ratio of oxyhydrogen gas in the liquid fuel can be stably mixed at around 4% to 7% even if a vortex pump or the like is used. Therefore, there was an unsolved part as a gas-liquid mixed combustion device.
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％に近いクリーンな燃焼をすることが課題である。 The present invention is to freely adjust the mixing ratio of oxyhydrogen gas to liquid fuel to enable combustion, increase the mixing ratio of oxyhydrogen gas, and perform clean combustion in which the combustion efficiency of liquid fuel is close to 100%. Is an issue.
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、酸水素ガス発生装置で発生した酸水素ガスを混合して燃焼する予混合バーナーにあって、前記予混合燃料を燃焼するロータリーバーナー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接続管を有する気液混合ポンプが有り、液体燃料タンクに接続した液体燃料供給配管に連接している。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, and in order to solve the above problems, as in claim 1, a premix burner that mixes and burns oxyhydrogen gas generated by an oxyhydrogen gas generator. There is a gas-liquid mixing pump having a connecting pipe for sucking oxyhydrogen gas supplied from the oxyhydrogen gas generator between the rotary burner that burns the premixed fuel and the liquid fuel tank. It is connected to the liquid fuel supply pipe connected to. A premixed combustion device characterized in that the gas-liquid mixing ratio is adjusted so that combustion can be performed without causing cavitation.
本発明は酸水素ガスを液体燃料に気液混合し、燃焼装置で燃焼する場合、気液混合するにあたり、回転式ポンプ例えば過流ポンプ、ギヤーポンプ等を使用しない為にキャビテーションを起こさず酸水素ガスの必要量を予混合燃焼装置に供給することができ、液体燃料のクリーンな燃焼ができる。 In the present invention, when oxyhydrogen gas is mixed with a liquid fuel in a gas-liquid manner and burned in a combustion device, the oxyhydrogen gas does not cause cavitation because a rotary pump such as an overflow pump or a gear pump is not used in the gas-liquid mixing. The required amount of liquid fuel can be supplied to the premixed combustion device, and the liquid fuel can be burned cleanly.
