Standard and testing procedures in laboratory for coal log fabrication
Metadata[+] Show full item record
The quality of coal logs for transportation by CLP (Coal Log Pipeline) is determined mainly by the water resistance and wear resistance of the coal logs under conditions similar to those encountered in future commercial CLP. There are many factors that affect the quality of coal logs. They must be clearly specified and controlled in order to insure that good quality coal logs and consistent results are produced. The purpose of this document is to specify the procedures used in manufacturing and testing coal logs at the Capsule Pipeline Research Center (CPRC), University of Missouri--Columbia and Rolla campuses. All researchers on the two campuses must follow these procedures so that test data are reproducible on different days by different experimenters, and test results can be properly compared between researchers.
