Anthracite calcination in rotary furnaces belongs to the mostly used technologies of the coke production. In the process of combustion air and gas to the rotary kiln is heated to the temperature of anthracite calcination. Calcined anthracite is discharged to the cooler where the material cools in contact with the furnace wall by free cooling or by water respectively. The flue gases leaving the furnace are without further use. The disadvantage of this process is the low use of flue gases heat and heat of calcinated anthracite respectively. A new way of calcination process was designed which uses the heat of flue gases and heat of produced coke for the production of heat or power. The proposed method allows to reach the maximum energy of the calcination process. Improvement of the contemporary solution is the waste heat energy using for the energy production.
