Latest Patents

Heikki Siirilä holds a patent for a "Method for reducing build-up on a roasting furnace grate." This innovative method addresses the issue of build-up that forms on the grate of a fluidized-bed furnace during the roasting of fine-grained materials, such as concentrate. The invention involves feeding the concentrate into the roaster from the wall of the furnace while introducing an oxygen-containing gas through gas nozzles located under the grate. This process not only fluidizes the concentrate but also facilitates its oxidation during fluidization. Notably, the oxygen content of the gas fed below the concentrate feed point is increased compared to other areas, optimizing the roasting process.
