<p>Appts. for charging a fluid, partic. a gas, into a reaction chamber, which oscillates about longitudinal axes, incorporates ducts circulating the gas near the wall of the chamber and discharging into nozzles near the roof of the chamber, connecting the ducts with the interior of the chamber. The nozzles are positioned along chords and so that, during the oscillation of the chamber, they are never covered by the products in the chamber. They are distributed symmetrically on one side and the other of a longitudinal plane. They can be opened or closed by automatically operated butterfly valves, according to their position so as to direct the gases constantly onto the base of the materials being treated. The invention increases the efficiency of the treatment to which the prods. are subjected, whether they be solid, liqs. or pastes, compared to existing reaction chambers. Combustion is more efficient. The construction is simpler.</p> |
