Bio Coal : Malaysia Bio Coal Producer

In Malaysia, rice husks, empty fruit bunch (EFB), palm kernel shell (PKS), sawdust, etc., are some of the bio-wastes that can be used to produce biocoals. Some researchers noted that rice husks worked the best, as they are abundant all around the globe, and are inexpensive. Malaysia relies heavily on coal as a fuel source for power generation.

Emergency inerting systems for coal-grinding applications

2011-10-21  Description of the inerting process in coal-grinding systems Inerting systems avoid dust explosions and smouldering fires in silos, coal mills and filter equipment by creating an inert atmosphere. In the case of abnormal levels of carbon monoxide (CO), oxygen or heat, the inerting process is initiated automatically through a process-control system.
