Liquefaction of coal cargo

Key words: 

coal, liquefaction, sea transportation.


Coal is the most abundant and widely distributed fuel in the world. Coal properties vary widely depending strongly on the origin of the coal and they are empirically determined by several tests.  Liquefaction is a phenomenon in which some solid bulk cargoes lose their strength for generally short time but nevertheless long enough for liquefaction to be the cause of many failures, deaths and major financial losses. There are many factors that influence the ability to liquefy such as particle size and moisture content.  The main purpose of this paper is to investigate the impact of coal properties on the ability to liquefy. The relation between the degree of fragmentation and the value of TML was analysed. In addition, the possibility of using different method determination of TML was discussed.
