FIELD: coke industry. SUBSTANCE: method involves addition of coke swelling inhibitor to preliminarily burned coke particles, interaction of coke particles with inhibitor at elevated temperature, and cooling reaction product. As inhibitor, sodium carbonate is used in quantity 0.2-2.5% based on burned coke weight in the form of aqueous solution or granulated powder, and interaction is carried out at 1200-1400 C for period of time sufficient for formation of reaction deposit containing sodium all over the bulk of coke particles. Installation contains extended cylindrical burning kiln and elongated cylindrical cooler, the both mounted for rotation, and a chamber to collect cooled burned coke particles on discharge end of cooler. In addition, installation includes retention chamber to collect and retain burned coke particles prior to be loaded into cooler, which chamber communicates with discharge chamber; a means forming hot chamber connected with retention chamber and admission end of cooler; and a means to bring dry granulated swelling inhibitor in contact with burned coke particles. EFFECT: enhanced. 6 cl, 5 de
