| 520 | 3 | |a Overall heat-transfer coefficients were obtained in a single-tube loop for a smooth tube and two fluted tubes proposed for use in a geothermal brine upflow VTE pilot plant. Tests were run at steam temperatures from 250 to 390 deg F, flow rates of 0.5 to 2.5 gpm, and steam to brine DELTA Ts of 10 to 30 deg F using demineralized water and 3% NaCl solutions. In each case the liquid entering the tube flashed through a DELTA T equal to the steam- brine DELTA T. The tubes tested were a 3/4-in. smooth stainless steel tube, a 1-in. double- fluted CuNi tube, and a 7/8-in. double-fluted Al brass tube. Average heat transfer coefficients using 3% NaCl were as follows: for the stainless steel tube, 550 Btu/hr/ deg F/ft/sup 2/ at 250 to 765 at 390 deg F; for the CuNi tube, 2000 at 250 to 2600 at 390 deg F; for the aluminum brass tube, 1750 at 250 deg to about 2650 at 390 deg F. Flow rate and DELTA T, in general, had only small effects on the coefficients. (auth) | |
