Steel plates (X5CrNi18-10) with different roughness and wettability were prepared. Incrustation of MgSO4·7H2O under laminar flow (Re = 59–178) was investigated. Influence of surface properties and fluid velocity on incrustation was found. Wettability and surface roughness cannot be considered separately. Analysis of heat transfer and incrustation time-lapse videos are presented.
