Latest Patents

One of Ahvenainen's latest patents is related to a "Method of Sealing a Rotary Drum Connection." This invention provides a sealing arrangement between a rotary drum kiln and its stationary end that is arranged in material flow relation. The seal's enhanced effectiveness also requires less maintenance. By feeding pressurized gas, such as air, to the connecting area, he ensures that minimal air escapes while effectively preventing the leakage of process gas and solid matter dust. This innovative gas flow design allows the stationary and moving surfaces to work in tandem without excessive rubbing.

Another notable patent introduced by Ahvenainen is a "Cooler for Rotary Kilns." This invention consists of two cylindrical housings that are disposed one inside the other and rotate together with the kiln. These housings create an annular space where the hot material from the kiln enters and cools down by flowing counter-currently against the cooling gas. This inventive design not only increases efficiency but also optimizes the cooling process, highlighting his forward-thinking approach to improving kiln technology.
