摘要：

A theoretical substantiation and the results of experimental studies of the behavior of impurities in the volume of the boiling medium in equipment in nuclear power and heat-and-electricity plants are presented. It is hypothesized that coarsely dispersed sludge accumulates at the boundary of the turbulent nucleus and viscous sublayer and only a small part of it settles on the heat-transmitting surface. If this hypothesis is correct, then sludge should accumulate and be expelled into the main volume of the working medium when the heat load changes, just like soluble impurities. The experimental data confirm this hypothesis.
