Pulsation reactors are used to subject materials to a rapid thermal shock, with extremely short residence times; typically used to produce ultrafine powders with special material properties.
The Pulsation Reactor, an IBU-tec innovation, primarily consists of a combustion chamber, a resonance tube and a product filter. Within the combustion chamber, a periodic-transient flame generates a pulsing hot gas stream. This gas stream is highly turbulent and carries the fed raw material with it. The pulsation tube serves as the reaction chamber, in which the desired reactions take place in 0.05 to 2 seconds. The end of the tube leads to a filter, where the newly created or processed materials separate from the offgas and deposit. Extremely fast heating and cooling rates differentiate the pulsation rector from other thermal systems. The material receives “thermal shock treatment” within a minimal residence time, in which a massive heat and material exchange takes place. This treatment leads to special properties in the material, which can be very advantageous. For example, the production and activation of catalysts, doping, or for materials with a special morphology.
