On the effect of heating method on burnout in a steam-generating tube

Experimental data obtained by various authors on burnout under non-uniform heating with an electric current and hot coolant are analyzed. Linear and step laws of heat release on electric heating are considered. Results of experimental investigation into critical heat flows using one-tube model of a steam generator with sodium heating are presented. Recalculation of experimental data obtained on electric-heated models according to the conditions of a steam-generating channel with sodium heating has been carried out. A conclusion has been drawn on the basis of all the data that in the considered region of parameters: qsub(max)/anti q < 1.6, P=70-175 bar, rhoW=350-3000 kg/m2s there is no a considerable effect of the heating method on critical steam contents. There are no works where the effect of the heating method on burnout in the range of other pressures and mass velocities is noted
