    Abstract: A process and system is provided for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal. This process includes partially drying the particulate matter and feeding, the partially dried particulate matter to a briquetting apparatus (38) under conditions such that water vapour is released from the particulate matter during feeding. The particulate matter is passed through briquette forming rollers (44, 46) to form briquettes (47). The released water vapour 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 that is fed to the briquetting apparatus is surrounded by and intermixed with a gaseous component containing 70 to 100 % by volume of water vapour at the point where it enters the briquette-forming part of the briquetting apparatus, such that when the particulate matter is compressed during briquette formation, the water vapour liquefies and the pressure buildup of gaseous material in the thus-formed briquettes is minimised. This reduction in the pressure buildup of gaseous components also acts to reduce blow-back of gases as the coal fines are being formed into briquettes.

    Abstract translation: 提供了一种用于压块颗粒物质如含湿烟气和次烟煤的方法和系统。 该方法包括部分干燥颗粒物质,并将部分干燥的颗粒物料送入压块装置(38),使得在进料过程中从颗粒物质中释放出水蒸气。 颗粒状物质通过块状成形辊(44,46),形成团块(47)。 释放的水蒸汽基本上置换或防止大部分其它气体组分从围绕/或与颗粒物质混合的大气中进入。 进料到压块装置的颗粒物质在含有70〜100体积%的水蒸气的气态成分被包围并混合,在其进入压块装置的团块形成部分的位置, 在团块形成期间物质被压缩,水蒸汽液化并且由此形成的团块中的气态物质的压力累积最小化。 气态组分的压力累积的这种减少也起到减少当煤细粉形成团块时气体的吹回。
