Foss and Paul Larsen, delivered the first cement plant to a manufacturer in Sweden. In 1898, he was the first to introduce the rotary kiln in the cement industry and became later one of the major suppliers of rotary kilns worldwide. Thomas A.

Avoiding the formation of rings in rotary kilns is an issue of primary concern to the cement production industry. We developed a numerical combustion model that revealed that in our case study rings are typically formed in zones of maximal radiative heat transfer. This local overheating causes an overproduction of the liquid phase of the …Web
