DescriptionDust catcher drawing.png |
Français : Pot à poussière et descente de gaz d'un haut fourneau. Cette conception, décrite comme primitive par l'auteur, s'est finalement avérée plus efficace que ses variantes "améliorées". English: Dust catcher (or dust pot) and gaz downcomer of a blast furnace. This design, described as an early form by the author, was finally recognized as more efficient than its "upgrades". |
