Book Description
The 1.5'' diameter screw feeder (NB V-12) development testing progressed satisfactorily. Several conclusions were drawn. With external heat operation: Only a minor portion of the total power (energy) is consumed mechanically in driving the screw; a large amount of energy is used to heat the coal and evaporate moisture in the input coal; operation without a conical tip at the screw discharge end yields better performance in comparison with the conical tip; the overall performance of an increasing volume screw is slightly better than that of 3/4 pitch length screw (the 3/4 pitch length screw requires substantially more mechanical specific power in comparison with the increasing volume screw); and the injection mode yields slightly better performance and is less sensitive to the screw configuration in comparison with the extrusion mode. Without external heat operation: The coal output is essentially independent of gas back-pressure and is directly proportional to the cycle rate in injection mode; the feeder operation is independent of the coal properties at elevated temperature and hence this operation offers considerable advantage over that with external heat operation. The shakedown testing of the 5.5'' diameter screw feeder and its test system continued. The tests to date have provided valuable information for design alterations to the feeder and system which should greatly improve overall operation; however, it has delayed the program.
