Increasing the efficiency of the autothermal processing of coal in a fluidized bed

The results of work on increasing the efficiency of heat energy production in standard boiler units using the «TERMOKOKS-KS» technology by intensifying the energy-technological processing of coal in a fluidized bed are presented. A significant increase in productivity has been established when removing small grades from coal and subsequent drying of coal, which makes it possible to reduce the cost of the obtained heat energy. The coarsening of the particles of the obtained browncoal coke with a decrease in the moisture content of the coal was revealed, which increases its transport characteristics. The range of temperatures of stable operation of the fluidized bed has been increased, due to which the product range of the «TERMOKOKS-KS» process has been expanded. The heat and material balances of the processes of combined production of heat energy and carbon-containing products are presented.
