Abstract:
(EN) The purpose of the present invention is to enable a boil-off gas to be processed while simultaneously utilizing energy of the boil-off gas. Provided is a boiler that is supplied with a boil-off gas generated in an LNG tank which stores an LNG, wherein the boiler comprises a burner (23) that burns the boil-off gas. The burner (23) includes: a continuous discharge-type igniter (56); and an intermittent discharge-type igniter (43) having a higher spark frequency during ignition than the continuous discharge-type igniter. The intermittent discharge-type igniter (43) is used when processing the boil-off gas in the boiler.
(FR) La présente invention a pour but de permettre le traitement d'un gaz d'évaporation et l'utilisation simultanée de l'énergie du gaz d'évaporation. À cet effet, l'invention concerne une chaudière alimentée en gaz d'évaporation produit dans un réservoir de GNL permettant de stocker du GNL, la chaudière comprenant un brûleur (23) destiné à brûler le gaz d'évaporation. Le brûleur (23) comprend : un allumeur du type à décharge continue (56) ; et un allumeur du type à décharge intermittente (43) présentant une fréquence plus élevée d'étincelles pendant l'allumage que l'allumeur du type à décharge continue. L'allumeur du type à décharge intermittente (43) est utilisé lors du traitement du gaz d'évaporation dans la chaudière.
(JA) ボイルオフガスを処理することができ、同時に、ボイルオフガスのエネルギーを利用することを目的とする。ボイラは、LNGを貯留したLNGタンクで発生したボイルオフガスが供給されるボイラであって、ボイルオフガスを燃焼するバーナ(23)を備える。バーナ(23)は、連続放電式イグナイタと、連続放電式イグナイタ(56)よりも点火の際のスパークの頻度が多い間欠放電式イグナイタ(43)とを有している。間欠放電式イグナイタ(43)は、ボイラにおいて、ボイルオフガスを処理する際に用いられる。
