Latest Patents

Siirilä's latest patents include an "Arrangement and method for reducing build-up on a roasting furnace grate." This invention addresses the issue of build-up formed on the grate of a fluidized-bed furnace during the roasting of fine-grained materials, such as concentrate. The method involves feeding the concentrate into the roaster furnace from the wall and introducing oxygen-containing gas via gas jets under the grate. This process helps to fluidize the concentrate and oxidize it effectively. Additionally, he has developed a "Method for regulating a roasting furnace," which allows for independent regulation of gas flow through a separate grate section known as the overflow grate. This innovation is particularly advantageous in optimizing the roasting process.
