Abstract
The principles of calculation of vortex chambers, in which flash heat processing of brown coal or a hard-coal beneficiation product with an ash content of 25–40% produced along can be run, are shown. Fast heat treatment of this type makes it possible to reduce the initial moisture content of brown coal from 35–40 to 2–12% and of coal preparation products, from 20–25 to 10–12%. In the basic parameters (fuel consumption, specific amount of metal, etc.), this method of reducing the moisture content is superior to traditional methods for drying coals and their preparation products (in drum, pipe, fluid-bed, or pneumatic dryers). After decreasing the moisture content of brown coals to a value of ≤3%, their bertinization, i.e., preparing a product with properties close to that of grade D coals, is also performed.
