COMBUSTION APPARATUS

To provide a combustion apparatus capable of improving economical efficiency and work efficiency in operation while performing safe operation even when using hydrogen gas as fuel gas.SOLUTION: A combustion apparatus includes a control device S that can control a first flow regulating valve V1 capable of adjusting a flow rate of hydrogen gas flowing in hydrogen gas flowing piping L1 and a second flow regulating valve V2 capable of adjusting a flow rate of hydrocarbon gas flowing in hydrocarbon gas flowing piping L2. The hydrocarbon gas flowing piping L2 is in communication and connected with a downstream side piping portion on the downstream side of an installation position of the first flow regulating valve V1 of the hydrogen gas flowing piping L1 in the state where hydrocarbon gas can flow. The control device S is configured to execute hydrocarbon gas purge control for purging hydrogen gas in the downstream side piping portion of the hydrogen gas flowing piping L1 by using hydrocarbon gas with the first flow regulating valve V1 closed and the second flow regulating valve V2 opened.SELECTED DRAWING: Figure 1 【課題】燃料ガスとして水素ガスを用いる場合にも安全な運用を図りながら、経済性の向上及び運用における作業効率の向上を図り得る燃焼装置を提供する。【解決手段】水素ガス通流配管Ｌ１を通流する水素ガスの流量を調整可能な第１流量調整弁Ｖ１と、炭化水素ガス通流配管Ｌ２を通流する炭化水素ガスの流量を調整可能な第２流量調整弁Ｖ２とを制御可能な制御装置Ｓを備え、炭化水素ガス通流配管Ｌ２は、水素ガス通流配管Ｌ１の第１流量調整弁Ｖ１の設置位置より下流側の下流側配管部位に対し、炭化水素ガスを通流可能な状態で連通接続されており、制御装置Ｓは、第１流量調整弁Ｖ１を閉止状態とすると共に第２流量調整弁Ｖ２を開放状態として、水素ガス通流配管Ｌ１の下流側配管部位の水素ガスを炭化水素ガスによりパージする炭化水素ガスパージ制御を実行可能に構成されている。【選択図】図１
