Le rev\u00eatement du four de craquage doit r\u00e9pondre \u00e0 des exigences \u00e9lev\u00e9es en mati\u00e8re de mat\u00e9riaux isolants r\u00e9sistants au feu, qui doivent pr\u00e9senter une bonne \u00e9tanch\u00e9it\u00e9 \u00e0 l'air et une faible conductivit\u00e9 thermique. Par cons\u00e9quent, la paroi du four de craquage d'un grand dispositif de craquage de l'\u00e9thyl\u00e8ne adopte une structure en briques l\u00e9g\u00e8res dans la zone de lavage du flux d'air du br\u00fbleur, et d'autres parties adoptent une structure en fibres et modules de fibres r\u00e9sistants au feu avec de bonnes performances d'isolation thermique.<\/p>\n

\"four<\/p>\n

Les conditions de fonctionnement de chaque partie \u00e9tant diff\u00e9rentes, les mat\u00e9riaux d'isolation r\u00e9sistants au feu utilis\u00e9s sont \u00e9galement diff\u00e9rents. Lors de la construction du rev\u00eatement du four de craquage, celui-ci peut \u00eatre divis\u00e9 en quatre parties en fonction de sa structure : la chambre de radiation, la section de transition, la section de convection, le conduit de fum\u00e9e et la chemin\u00e9e. La configuration sp\u00e9cifique des mat\u00e9riaux isolants r\u00e9fractaires pour chaque partie est la suivante :<\/p>\n

1. Chambre de radiation<\/h2>\n

The radiation chamber is the heating reaction site for light hydrocarbons in the cracking medium. The furnace temperature is 1260\u00b0C. There are oil and gas burners on both sides of the wall and the bottom. The refractory insulation materials used in the bottom, side walls, and top of the radiant chamber are different.
\nA. The furnace bottom mainly uses insulation boards, insulation refractory bricks, refractory bricks, etc.<\/p>\n

B. Les parois lat\u00e9rales sont constitu\u00e9es de feutre de fibres c\u00e9ramiques, de panneaux isolants, de briques isolantes r\u00e9fractaires, de modules de fibres, de crochets, de plaques de fixation des crochets et de clous d'ancrage des modules de fibres.<\/p>\n

C. Le dessus de po\u00eale utilise principalement du feutre de fibre c\u00e9ramique, des modules de fibre et des clous d'ancrage de module de fibre.<\/p>\n

2. Section de transition<\/h2>\n

Comme la paroi du four de la chambre radiante, les parois lat\u00e9rales sont install\u00e9es avec des modules de fibres, les modules dans les parties de forme sp\u00e9ciale sont install\u00e9s avec des modules sp\u00e9cialement con\u00e7us, et la structure du rev\u00eatement de fond est la m\u00eame que celle du fond du four de la section radiante. Les mat\u00e9riaux requis pour la section de transition comprennent le feutre de fibre c\u00e9ramique, les panneaux d'isolation, les briques d'isolation r\u00e9fractaire, les modules de fibre et les clous d'ancrage des modules de fibre.<\/p>\n

3. Section de convection<\/h2>\n

Les panneaux des parois lat\u00e9rales sont pr\u00e9fabriqu\u00e9s avec des mat\u00e9riaux moul\u00e9s r\u00e9fractaires sur le sol, avec une \u00e9paisseur de 200 mm. Avec un panneau d'isolation de 100 mm d'\u00e9paisseur comme support, le rev\u00eatement de la plaque du tube d'extr\u00e9mit\u00e9 a \u00e9t\u00e9 construit \u00e0 ce moment-l\u00e0. La structure du rev\u00eatement de la bo\u00eete \u00e0 coude est un pav\u00e9 de fibres de 50 mm d'\u00e9paisseur (divis\u00e9 en deux couches de 25 mm). Les mat\u00e9riaux requis pour les parois lat\u00e9rales comprennent des panneaux en fibre c\u00e9ramique, des pi\u00e8ces moul\u00e9es, des clous d'ancrage en forme de \"Y\" et des clous d'ancrage en forme de \"V\". Les bo\u00eetes coud\u00e9es n\u00e9cessitent des ancrages et du feutre en fibre c\u00e9ramique.<\/p>\n

4. Conduit de fum\u00e9e et chemin\u00e9e<\/h2>\n

La structure du rev\u00eatement de la chemin\u00e9e et du conduit de fum\u00e9e est constitu\u00e9e de b\u00e9ton r\u00e9fractaire d'une \u00e9paisseur de 50 mm. Elle n\u00e9cessite l'utilisation d'ancrages et de b\u00e9tons d'isolation.<\/p>\n
