ABSTRACT:
A method of heating multi-fractional materials is disclosed wherein additional streams of heat carrier gas of a comparatively high temperature are introduced in a stream of heat carrier which has a maximum-temperature heating zone and a comparatively low-temperature heating zone provided in the process flow. The additional streams are supplied only to the comparatively low-temperature heating zone in the main stream of heat carrier, thereby raising the temperature of the heat carrier stream. Multi-fractional materials are heated as they enter the comparatively low-temperature heating zone in the heat carrier stream and before they have entered the maximum-temperature zone.
The apparatus for implementing the method of heating consists of a plurality of heaters connected in a series relationship and having inlet tubes for supply of heat carrier and the materials to be heated, a means adapted for separating heated materials from waste heat carrier, and discharge tubes for the above products.
The apparatus is also provided with means for producing a heat carrier and inlet tubes for heat carrier supply to the heaters. Specific embodiments of the apparatus may have additional means for producing a heat carrier provided for each of the heaters.
