摘要

Local heat transfer coefficients were studied for the superheated steam flow inside coled tubes. The parameter range investigated involves the following data: P= 4−216 bars: = 400−4000 kg/m2sec, q = 2·104− 16·106W/m2, tf from 500°C to ts.
Analysis of the experimental data has resulted in the determining of border values of parameters of two zones: a zone within which the superheated steam condensation takes place and a zone where the steam is subjected only to cooling with no changes in its aggregate state.
The calculation recommendations for determining heat transfer coefficients are proposed for each zone.
