An arrangement for a heat exchange surface in a boiling application that retains particulate material between fins to provide nucleate boiling sites. The heat exchange surface most typically is part of a heat exchange tube and retains the particulate material by transversely extending the tops of the fins. The fins and extended tops form channels with a restricted opening at the top of the channel that prevents passage of the particulate material out of the channel. The surface may be formed on the inside or outside of tubes.
