Carbonizing etc. , coal etc

Abstract

In drying, carbonizing, and distilling coal, shale, etc., by passage through a heated retort, the material is spread in a thin layer over the heating surface by a conveying-screw with a shallow thread. The retort is heated by a bath of molten metal, and the conveyingscrew intermeshes with a scraper screw of smaller diameter, and of a different hand; the screws are mounted on shafts geared together by wheels. The material after passing through the retort is delivered into a chute closed at the bottom by an arc-shaped water seal carried on arms and opened periodically by a lever.
