Results of experimental research represent conditions of heat transfer deterioration for boiling potassium in a straight-through evaporator with a composite capillary-porous structure in the output section. A region of mass velocities is identified, where boundary vapor content, with heat transfer deterioration in the composite capillary-porous structure, is higher than in smooth-tube evaporators and evaporators with a simple capillary structure.
