Some typical problems related to pulverized-coal transport for steam generators have been investigated in a long-term test program.

The investigation has provided information relative to the performance of a commercial-type exhauster handling air-coal mixtures, friction factors for 8 and 12-in-diam pipe handling air-coal mixtures, general information as to the flow characteristics of air-coal mixtures in various piping systems, and methods and means for control of coal drifting in horizontal pipe.

Friction factors in the range of 0.017 to 0.035 for 8 and 12-in. pipe are indicated for the usual operating range.
