| Description |
Français : Coupes du four à cornues inventé par Carl Wilhelm Siemens en 1867. Les cornues sont charges par le haut. une pièce centrale, consistant en des entonnoirs inversés superposés, sert à drainer les gaz qui sont amenés dans les condenseurs E. Ce four, incompatible avec les opération de décrassage, semble ne pas avoir eu de carrière industrielle. |
