The paper presented the results of experimental investigations into boiling heat transfer on heating surface covered with copper, fibrous, porous layers at simultaneous image registration. Significant heat transfer enhancement in comparison with a smooth surfacewas observed. The measurement stand allowed boiling process registration while determining boiling curves obtained at increased and decreased heat flux. Visualisation experiments aimed at the registration of vapour formation inside the structure -"intralayer boiling crisis".
