Abstract

Abstract

In order to evaluate the difference of condensation heat transfer law between single tube and steam containing air outside the tube bundle under different heat transfer tube structural parameters, based on a single tube with an outer diameter of 12~19 mm, an inclination angle of 0°~90° and a 3 × 3 tube bundle, an experimental study was carried out in the range of pressure 0.2~1.6 MPa and air mass share 12%~87%. The results show that the influence of tube diameter and inclination angle on single tube and tube bundle shows different rules in different pressure ranges. When the pressure is less than 0.8 MPa, the condensation heat transfer of the tube bundle is affected by the tube diameter and inclination angle, which is the same as that of a single tube. The condensation heat transfer coefficients of both increase with the decrease of tube diameter and inclination angle. At 0.8~1.6 MPa, the condensation heat transfer of tube bundle is significantly different from that of single tube due to the influence of tube diameter and inclination angle. The law of consistency and difference is analyzed according to the mechanism of the effect of non-condensable gas on steam condensation heat transfer.
