Mulled Coal: A beneficiated coal form for use as a fuel or fuel intermediate

PDF Version Also Available for Download.

Description

During the past quarter Energy International has evaluated additional mull formulations with varying reagent additives, mixing times, and particle sizes. The Environmental Review was completed and conceptual designs developed for the Mull Preparation and CWF Conversion Systems. As these technical developments move toward commercial application, the needs for coordinated efforts and integrated requirements have become increasingly apparent. Systems are vitally needed to integrate energy delivery systems from the raw resource through processing to application and end use. Problems have been encountered in the preparation of conventional coal-water fuels that mutually satisfy the requirements for storage stability, handling, preparation, atomization, combustion, ... continued below

Description

During the past quarter Energy International has evaluated additional mull formulations with varying reagent additives, mixing times, and particle sizes. The Environmental Review was completed and conceptual designs developed for the Mull Preparation and CWF Conversion Systems. As these technical developments move toward commercial application, the needs for coordinated efforts and integrated requirements have become increasingly apparent. Systems are vitally needed to integrate energy delivery systems from the raw resource through processing to application and end use. Problems have been encountered in the preparation of conventional coal-water fuels that mutually satisfy the requirements for storage stability, handling, preparation, atomization, combustion, and economics. Experience has been slow in evolving generic technologies or products and coal-specific requirements and specifications continue to dominate the development. Thus, prospects for commercialization remain highly specific to the coal, the processor, and the end use. Developments in advanced beneficiation of coal to meet stringent requirements for low ash and low sulfur can be anticipated to further complicate the problem areas. This is attributable to the beneficiated coal being produced in very fine particles with a high surface area, modified surface characteristics, reduced particle size distribution range, and high inherent moisture.
