Some Technical Problems on Coal Slurry Transportation

Abstract

In Ohio, U. S. A., it succeeded to transport coal slurry by long pipe line for the first time in the world. After industrializing, they have continued every kinds of studies and improvements on this operation.
In other countries, also, the researches have been made on transportation and utilization of coal slurry.
This paper describes above next three problems of these studies:
1) Counter plan to the corrosion achieved on the pipeline. It is very important problem in the economical point of view. In U. S. A. they have successfully reduced the inhibitor cost one tenth by the long term study.
2) Control system of coal slurry transportation. There are more difficulties in coal slurry transportation than the other liquids transportation. These problems have been solved in U. S. A., and the control system of the pipeline has been completely automated.
3) Direct burning of coal slurry. In a German power station, it was accomplished by improving of oil burners of usual boiler.
