Abstract
The composition and properties of Kemorovo lignite are studied. Lignite is characterized by high moisture content and yield of volatiles, high chemical activity, and a high content of micro- and mesopores. The moisture absorption and moisture loss of lignite (piece sizes 3–8, 8–12, 12–25, and 25–50 mm) are studied as a function of the contact time with water and air. Industrial data are presented for the lignite temperature on storage in the batch yard at AO Kuznetskie Ferrosplavy. When a probe is introduced in the coal to depths of 400–1000 mm, its temperature varies from 68–78 to 78–90°C. With increase in holding time, it rises to 83–93°C. Recommendations are made for refinement of the technical instructions regarding lignite storage.
