Study on the Selection of Single-Screw Steam Compressors in Industrial Steam Supply

Selection and Application of Industrial Screw Compressors

The Challenge of Using the Single-Screw Compressor with Steam

Tests are reported on a small (110 mm diameter main rotor) singlescrew 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 atomisation into the suction. The test rig allowed preliminary runs to be made on nitrogen at 2990 and 5600 RPM. The best volumetric efficiency was only 57% and this was d...

Streams of Steam – The Steam Boiler Specification Case Study

FOCUS is a mathematics-based methodology for the development of distributed reactive systems. This paper sketches the expressiveness and the usefulness of the well-tuned concepts of FOCUS by its application of the requirements specification of a steam boiler, see [Abr96]. We demonstrate the support for non-specialists in formal methods by using userfriendly description techniques, here the stat...

Cash Flow Impacts of Industrial Steam Efficiency

Steam efficiency is a major opportunity for manufacturers to boost financial performance in an increasingly competitive environment. An immediate policy challenge is to raise manufacturers’ awareness of these opportunities. A major barrier to accomplishing this is the communications disconnect between plant superintendents and the financial decision-makers who set capital budgeting priorities. ...
