ABSTRACT:
An apparatus for rapid burning of thermally pretreated, at least partially calcined fine grained product to produce cememt clinker which includes a thermal reactor having a firing chamber and means for introducing the product to be treated in concurrent flow with and in the area of a flame in the firing chamber. The means for introducing the product includes a vertical shaft which discharges into the firing chamber, together with a deflector which is disposed in the area of the discharge orifice of the shaft, the deflector serving to deflect the hot product which strikes the deflector with substantial kinetic energy due to the force of gravity. The product is broken up into small particles by impacting with the deflector, and is directed substantially parallel to the flame in the firing chamber. The deflector extends at an obtuse angle relative to the axis of the shaft. The apparatus can be connected to a fuel supply and can be utilized as a burner. A feed for an ejection gas can also be provided and equipped with devices for mixing the gas with fuel or it can be connected to a fuel source itself.
