FIELD: chemistry.
SUBSTANCE: present invention relates to by-product coke industry. Coal (2) is heated in coke oven (1). Obtained coke (5a) is pushed out into coke quenching car (6) and moved to coke quenching device (7). Incandescent coke (5a) is quenched to a temperature below kindling temperature by means of steam (8) under exclusion of air. Steam (8) for quenching is first divided into at least into two substreams. One substream of steam (8) is fed into coke quenching device (7) from below upwards in vertical flow direction, and substream of steam (8) is fed into part of coke quenching device (7), in which coke (5a) to be quenched has a temperature of 500-900 °C. Obtaining synthesis gas (9).
EFFECT: invention enables to efficiently recycle coke heat.
