ABSTRACT:
A solid, low-sulfur, industrial fuel having a fuel value similar to bituminous coal, and a continuous process for producing the fuel from woody materials are presented. The process includes the step of initially predrying the materials if they are moist until the water content thereof is less than about 15%. The woody materials are then subjected to a limited carbonization. The materials are heated in a furnace or kiln until noticeable carbonization begins, and carbonization is permitted to continue until the fiberous structure of the materials disappears to thereby maximize production of solid fuel having a high content of volatile combustible matter. Subsequently, the solid fuel is cooled and conditioned against spontaneous combustion. The solid fuel may then be pulverized or compacted, and immediately used, stored, or transported. The process of this invention optionally may also produce a small quantity of gas having a fuel valve sufficiently high for use as burner fuel in the predryer.
