Title
(EN) IMPROVED SYSTEMS AND METHODS FOR UTILIZING FLUE GAS
(FR) SYSTÈMES ET PROCÉDÉS AMÉLIORÉS PERMETTANT D'UTILISER UN GAZ DE COMBUSTION
Abstract
(EN)
Systems and apparatuses for cooling flue gases emitted from an industrial facility, such as a coke oven in a coke manufacturing plant. A representative system includes a heat recovery steam generator (HRSG) having a steam generation system that converts liquid feedwater into steam by absorbing heat from the flue gases. The steam generation system includes a plurality of tubes that carry the liquid water feedwater and the steam. Some or all of the tubes include steel and a non-corrosive material cladded to the steel that helps to reduce corrosion caused by the high temperature flue gases and extremely corrosive contaminants within the flue gas that can corrode steel.
(FR)
L'invention concerne des systèmes et des appareils pour refroidir des gaz de combustion émis par une installation industrielle, telle qu'un four à coke dans une usine de fabrication de coke. Un système représentatif comprend un générateur de vapeur à récupération de chaleur (HRSG) ayant un système de génération de vapeur qui convertit l'eau d'alimentation liquide en vapeur par absorption de la chaleur dégagée par les gaz de combustion. Le système de génération de vapeur comprend une pluralité de tubes qui transportent l'eau d'alimentation liquide et la vapeur. Certains ou tous les tubes comprennent de l'acier et un matériau non corrosif plaqué sur l'acier qui aide à réduire la corrosion provoquée par les gaz de combustion à haute température et les contaminants extrêmement corrosifs à l'intérieur du gaz de combustion qui peuvent corroder l'acier.
