Measured Performance of Direct-Contact Jet Condensers

摘要

Measured heat transfer rates and condensation efficiencies of water jets condensing steam at pressures in the range of 0.9 to 4.0 kPa (6 to 29 exp 0 C, saturation temperatures) are reported. Experimental variables include jet Reynolds number, water inlet temperature, steam-to-water ratio, and the concentration of noncondensible gases. Measured Stanton number appears to be a strong function of the concentration of the noncondensibles and a weak function of other variables. At minimal level of noncondensibles, the Stanton number takes on a value of 0.0017. A description of the apparatus and initial set of results are presented. (ERA citation 07:046328)
