THE CHALLENGE OF USING A SINGLE-SCREW COMPRESSOR WITH STEAM.

Author(s) : HASELDEN G. G., YELL M.

Summary

TESTS ARE REPORTED ON A SMALL (110 MM DIAMETER MAIN ROTOR) SINGLE-SCREW AIR COMPRESSOR ADAPTED FOR USE WITH STEAM. A NOVEL GATEROTOR DESIGN WAS EMPLOYED WITH SLIDING PADS TO TAKE UP TOOTH FLANK CLEARANCES. THERE WAS ALSO WATER ATOMIZATION INTO THE SUCTION. THE TEST RIG ALLOWED PRELIMINARY RUNS TO BE MADE ON NITROGEN AT 2,990 AND 5,600 RPM. THE BEST VOLUMETRIC EFFICIENCY WAS ONLY 57% AND THIS WAS DUE TO EXCESSIVE CLEARANCES IN CERTAIN LOCATIONS. RUNS ON STEAM GAVE MAXIMUM VOLUMETRIC EFFICIENCIES OF 30%. THE ADDITIONAL LOSSES WERE DUE TO HEAT TRANSFER EFFECTS, BOTH STEADY-STATE AND TRANSIENT.
