Electrochemical technique was applied to analyze the heat distribution in a tube bank in a bubbling gas-liquid flow column reactor. Results of the research on distribution of heat transfer rate on the surface of horizontal oriented tube bundles with two-phase gas-liquid crosswise flow in shell side of heat exchangers were presented in the paper. Basing on the obtained results, authors recognize electrochemical technique as very useful and of a great potential. It's noteworthy since it provides for finding mean and local heat transfer coefficients that result from conditions in both hydraulic and thermal developing region. Moreover, this technique seems to be low cost one and is the most accurate of all indirect methods of determining heat transfer coefficient.
