Phase de s\u00e9chage<\/h3>

Depuis le d\u00e9but de l'allumage jusqu'\u00e0 ce que la temp\u00e9rature du four atteigne 160 \u00b0C, l'humidit\u00e9 contenue dans la tige de charbon du m\u00e9canisme s'\u00e9vapore principalement gr\u00e2ce \u00e0 la chaleur externe et \u00e0 la chaleur g\u00e9n\u00e9r\u00e9e par la combustion elle-m\u00eame. La composition chimique de la tige de charbon du m\u00e9canisme a \u00e0 peine chang\u00e9.<\/p>

La phase initiale de carbonisation<\/h3>

\u00c0 ce stade, la chaleur de la tige elle-m\u00eame est principalement g\u00e9n\u00e9r\u00e9e pour augmenter la temp\u00e9rature du four du four de carbonisation<\/strong><\/a> entre 160 et 280 \u00b0C. \u00c0 ce moment, la mati\u00e8re ligneuse subit une r\u00e9action de d\u00e9composition thermique et sa composition commence \u00e0 changer. Parmi ceux-ci, la composition instable, telle que l'h\u00e9micellulose, se d\u00e9compose pour former du CO2, du CO et une petite quantit\u00e9 d'acide ac\u00e9tique.<\/p>

Phase de carbonisation compl\u00e8te<\/h3>

La temp\u00e9rature \u00e0 ce stade est de 300 \u00e0 650 \u00b0C.<\/p>

\u00c0 ce stade, le mat\u00e9riau en bois subit une d\u00e9composition thermique brusque, et un grand nombre de produits liquides tels que l'acide ac\u00e9tique, le m\u00e9thanol et le goudron de bois sont produits. De plus, des gaz inflammables tels que le m\u00e9thane et l'\u00e9thyl\u00e8ne sont g\u00e9n\u00e9r\u00e9s, et ces gaz inflammables peuvent \u00eatre br\u00fbl\u00e9s par un cycle de contr\u00f4le de vanne. La d\u00e9composition thermique et la combustion des gaz g\u00e9n\u00e8rent une grande quantit\u00e9 de chaleur, provoquant une augmentation de la temp\u00e9rature du four, et le mat\u00e9riau en bois est distill\u00e9 \u00e0 sec pour se transformer en charbon \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es.<\/p>

Pour calciner du carbone \u00e0 haute temp\u00e9rature, en plus des trois \u00e9tapes ci-dessus, nous devons augmenter la chaleur afin que la temp\u00e9rature dans le four continue d'augmenter jusqu'\u00e0 environ 800 \u00b0C \u00e0 1000 \u00b0C, de sorte que les substances volatiles restantes dans le charbon puissent \u00eatre \u00e9vacu\u00e9es et que le charbon puisse \u00eatre am\u00e9lior\u00e9. La teneur en carbone du charbon augmente la structure graphite du carbone et am\u00e9liore la conductivit\u00e9 \u00e9lectrique.<\/p>","protected":false},"excerpt":{"rendered":"
