Processing of Low-Demand Coal and Other Carbon-Containing Materials for Energy Production Purposes

Abstract

The main area of coal application is energy production. During such stages as min-ing, transporting, treatment, storing and processingof coal, a large number of small products are formed, such as screenings, spills, sludges, etc. Such products are not usedand significantly pollute the environment. Meanwhile, after agglomeration, they can eas-ily be used for the production of thermalenergy. Of all the known agglomeration meth-ods, briquetting is most suitable. The technology of obtaining flammable briquettesbased on coal is developed. A technology has also been developed to produce fuel bri-quettes from coal slurries and paper waste.The use of coal slurries and paper waste as binder materials makes it possible to obtain a fuel pellet that is simple in production andcomposition and at the same time allows to utilize coal and paper wastes. The technolo-gy of obtaining fuel extrudates (briquettes)from wood and shale wastes, as well as wood, shale waste and sludge was developed. Thus, technologies have been developed toproduce fuel briquettes from various types of low-demand carbon-containing materi-als for domestic use.
