ABSTRACT:
A process and system for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal includes partially drying and feeding the particulate matter to a briquetting apparatus under conditions such that water vapor is released from the particulate matter during feeding. The released water vapor substantially displaces or prevents the ingress of a large proportion of other gaseous components from the atmosphere surrounding an/or intermixed with the particulate matter. The particulate matter is surrounded by and intermixed with a gaseous component containing 70% to 100% by volume of water vapor where it enters the briquetting apparatus, such that when the particulate matter is compressed, the water vapor liquefies and the pressure buildup in the thus-formed briquettes is minimized. This reduction in the pressure buildup reduces blow-back of gases as the coal fines are formed into briquettes.
