Surface with micro-porous layer can enhance the boiling heat transfer efficiency of tube. The novel nucleate boiling tubes were manufactured by sinter-bonding metal particles on the outside surface. Two conventional bare tube reboilers were revamped with the novel tubes. Industrial application revealed that the revamps effectively increased the heat duty of reboilers with small heat transfer area and reduced heat transfer temperature difference across the heat exchanger. Porous surface tube was beneficial to heat transfer and operating cost.
