Experimental studies of heat transfer during steam condensation on a vertical multirow on-line bundle of slightly inclined coil tubes with and without noncondensable gas in the bundle

We present the results obtained from experimental studies and generalization of experimental data on heat transfer intensity during full condensation of downward flow of saturated steam on the outer surface of a vertical multirow in-line bundle of slightly inclined coil tubes at a steam pressure of 0.2–2.0 MPa. Specific features relating to heat transfer that occurs during steam condensation on a vertical coil tubing in the presence of heavy noncondensable gas in the space between its tubes are revealed.
