ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot-strip rolling mill in Duisburg. The animation shows how it all works.
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
