Title (EN) COAL-FIRED POWER GENERATION EQUIPMENT
(FR) ÉQUIPEMENT DE GÉNÉRATION D'ÉNERGIE AU CHARBON
(JA) 石炭火力発電設備
Abstract:
(EN) The present invention provides coal-fired power generation equipment that makes it possible to minimize the degradation of a denitration catalyst by preventing the surface of the denitration catalyst from becoming coated with sediment having an extremely small particle size. The coal-fired power generation equipment 1 is provided with: a coal pulverizer 30 that pulverizes coal in order to produce pulverized coal; a fine coal removal device 10 that is arranged downstream from the coal pulverizer 30 and that removes fine coal, i.e., fine pulverized coal; a combustion boiler 40 that burns the pulverized coal from which the fine coal has been removed in the fine coal removal device 10; and a denitration device 60 that is arranged downstream from the combustion boiler 40 and that removes nitrogen oxides included in exhaust gas generated when the pulverized coal is burned in the combustion boiler 40.
(FR) La présente invention concerne un équipement de génération d'énergie au charbon permettant de réduire au minimum la dégradation d'un catalyseur de dénitration en empêchant la formation, sur la surface du catalyseur de dénitration, d'un revêtement de sédiment présentant une taille de particules extrêmement petite. L'équipement 1 de génération d'énergie au charbon est pourvu : d'un pulvérisateur de charbon 30 qui pulvérise du charbon afin de produire du charbon pulvérisé ; d'un dispositif d'élimination 10 de fines de charbon qui est disposé en aval du pulvérisateur de charbon 30 et qui élimine les fines de charbon, c'est-à-dire, des fines de charbon pulvérisé ; d'une chaudière de combustion 40 qui brûle le charbon pulvérisé à partir duquel ont été éliminées les fines de charbon dans le dispositif d'élimination 10 de fines de charbon ; et d'un dispositif de dénitration 60 qui est agencé en aval de la chaudière de combustion 40 et qui élimine les oxydes d'azote inclus dans les gaz d'échappement générés lorsque le charbon pulvérisé est brûlé dans la chaudière de combustion 40.
(JA) 微小な粒径の堆積物が脱硝触媒の表面を被覆することを防ぐことで脱硝触媒の劣化を抑制できる石炭火力発電設備を提供すること。 石炭火力発電設備1は、石炭を粉砕して微粉炭を製造する微粉炭機30と、微粉炭機30の下流側に配置され微小な微粉炭である微小炭を除去する微小炭除去装置10と、微小炭除去装置10において微小炭が除去された微粉炭を燃焼させる燃焼ボイラ40と、燃焼ボイラ40の下流側に配置され燃焼ボイラ40において微粉炭が燃焼されて発生した排ガス中に含まれる窒素酸化物を除去する脱硝装置60と、を備える。
