Abstract: The subject of the invention is a process for igniting a sinter mix composed of a solid fuel and sintering material on a sintering machine in which the sinter mix is passed underneath an ignition kiln with closed end and side walls and a closed hood, whereby hot flue gases are generated in the ignition kiln above the sintering material and these hot flue gases heat and ignite the surface of the sintering material by radiation and convection. A rapid, uniform and economical ignition is thereby attained in that flue gases from one or more approximately stoichiometrically operated burners are introduced into the upper region of the igniting kiln and that gases with an increased oxygen content are introduced into the lower region in such a manner that a kiln atmosphere results which, in the upper region of the igniting hood, is hotter and relatively impoverished in oxygen, while in the lower region it is cooler and relatively oxygen enriched.

Abstract: A pair of transversely spaced and linked conveyor sections each include an upper support beam elongated in the direction of transport and having upper and lower longitudinal openings, and lifting members shiftably and liftably received in its interior; a lower lifting element extends along and beneath the support beam and converges upwardly toward the same in one longitudinal direction thereof. A wedge-shaped raising element has a planar upper face which extends parallel to an underside of the support beam; the raising element is actuated by the lifting element.
