Abstract

In this study, we perform experimental and analytical investigations of Corrosion effects on heat transfer in a Kettle Heat Exchanger. In this heat exchanger, the oil is flown inside the tube and the water is flown inside the shell, which is their duty to convert water to superheat steam. First, the causes of Corrosion in the heat exchanger are analyzed using optical and electronic microscopes and also metallographic experiments, that tube sintered ferrite, and perlite structure and grain size does not change in the surface crust boundary which illustrates the basic metal does not trigger the reaction. XRD and XRF experiments on the results of sediments in the external scale of silicate, calcium, and phosphorus tubes show that because of poor heat transfer, the feed water quality, the concentration of oxygen cells is made in that case sub-sediment Corrosion which is the subset of SCC Corrosion. This phenomenon reduces the outside of the tube thickness from 2. 11 mm to 1. 44 mm. Corrosion deposits in the outside surface of the tube cause a reduction in the heat transfer rate, which results in a hot spot, increasing tube oxidation intensity and Corrosion. This issue exactly matches with a gradual reduction in the output heat exchanger vapor pressure during operation which is determined experimentally. MATLAB software coding is the relationship between sediment mass and sediment heat resistance. The results illustrate that by passing time, the sediment mass and sediment heat and at the end of this instance are matched with experimental results.
