The characterization of brown coals of Kansk-Achinsk Basin for improved utilization in the coal-burning power stations

Kansk-Achinsk Brown Coal Basin in Siberia is the largest one of Russia. There are several large deposits in the Basin. Two main open cuts currently annually supply 35 million tonnes of brown coal for the pulverized fired boilers operated by number of Power Stations in Central Siberia. The main part of Kansk-Achinsk brown coals are characterized by low sulfur, nitrogen and heavy metal content. However, they differ in the ash content (within the range of 4--12%) and in the ash composition (in Ca, Al, Fe, Na, in particular). This has a major influence on the boiler fouling and slagging tendency. The paper describes the work in defining the geological, chemical and utilization characteristics of the coals from the different cuts and places of Kansk-Achinsk Basin. The emphasis on the ash fouling and slagging on burning brown coals from different places was made. The methods of coal preparation were developed to improve the utilization characteristics and to comply with the emission regulations. The preparation and burning of blended coals and coal-water slurry is the focus of the discussion. The technology of briquetted brown coal both with oil-derived binder and with no binder is described.
