Flue Gas Condensation in a Model of the Heat Exchanger: The Effect of the Cooling Water Flow Rate and Its Temperature on Local Heat Transfer

In boiler houses, the biggest heat energy losses are caused by flue gas being released into atmosphere. Installation of condensing exchangers allows reducing temperature released, condensation water vapor, and, thus, efficient use waste heat. There many investigations average transfer in different types exchangers. They indicate also that cooling flow rate and its important parameters defining vapor efficiency. Investigations local very limited. Only recently experimental Re number effect on model exchanger at a constant have started published. this paper, for first time, detailed from (long vertical tube) presented. The results revealed higher Rein, has stronger impact distribution along test section.
