Design Model for the Heat Transfer in a Short Straight Tube Boiler.

Abstract

A design model for the Short Straight Tube Boiler with a segmented fin-tube arrangement was developed. This model was integrated for a single tube applied in a computer program written in BASIC for the Hewlett Packard 9845 model B desk-top computer. Water-side Reynolds numbers were varied in order to investigate the performance of this boiler. For an overall tube length of 39.4 inches, a Reynolds number of 840 (29.65 lbm/hr) resulted in obtaining 50 deg superheat for an operating pressure of 600 psig. With these conditions, saturated boiling begins at 11.45 inches and superheating at 21.88 along the tube length. (Author)
