Abstract: A cement kiln having a tire injection system. The tire injection system comprises an entrance chute having an outer end portion protruding outwardly of a wall of the kiln and an inner end portion which protrudes into the kiln. The entrance chute further is disposed such that it is positioned tangentially to the kiln wall. The entrance chute includes a gate assembly having a cam follower assembly and a pivotally mounted gate member. The cam follower assembly causes the gate member to be urged pivotally between open and closed positions in response to movement of the cam follower assembly over a cylindrical camming wall positioned at a predetermined location relative to the kiln. When the cam follower assembly has caused the gate member to open, a plurality of tires or other items forming a source of supplemental fuel are injected into the entrance chute by one or more external tire injecting apparatuses synchronized in operation to rotation of the kiln.

Abstract: A retorting apparatus including a vertical kiln and a plurality of tubes for delivering rock to the top of the kiln and removal of processed rock from the bottom of the kiln so that the rock descends through the kiln as a moving bed. Distributors are provided for delivering gas to the kiln to effect heating of the rock and to disturb the rock particles during their descent. The distributors are constructed and disposed to deliver gas uniformly to the kiln and to withstand and overcome adverse conditions resulting from heat and from the descending rock. The rock delivery tubes are geometrically sized, spaced and positioned so as to deliver the shale uniformly into the kiln and form symmetrically disposed generally vertical paths, or "rock chimneys", through the descending shale which offer least resistance to upward flow of gas. When retorting oil shale, a delineated collection chamber near the top of the kiln collects gas and entrained oil mist rising through the kiln.

Abstract: An arrangement for charging an electric arc furnace with a relatively free-flowing charge of sponge iron or other iron-containing particles distributes the charge of particles within the furnace through a first chute before a melting stage of an electric arc steelmaking operation is begun, and then continuously through a second chute which extends through the roof of the furnace during the melting stage. The first chute extends from a hopper containing the sponge iron and can be moved when the roof is open to feed the charge into the furnace. A distributor cone at the lower end of this chute distributes the sponge iron in a predetermined pattern. A second chute affixed to the furnace roof and in communication therethrough with the interior of the furnace permits continuous charging of the furnace during operation.

When charging of the furnace is desired, the charge tube is lowered into the furnace to serve as a means for channeling charge material into the furnace. Preferably, the charge tube is operative to accumulate charge material while in its protected position and to release the material as it is lowered toward the furnace pot.

Abstract: A method and an apparatus is provided for charging particulate coal through ceiling holes into a coke oven. A conveyor above the coke oven ceiling is connected with each ceiling hole by a conduit. Mounted in the conduit is a first closure member which is movable to and from a position in which it permits gravity flow of coal from the conveyor to the ceiling hole.
