Special cleaning heat exchanger
However, the heat exchanger fouling and severe congestion, such as condensation,cooler, usually because the water contains large amounts of calcium and magnesium ions, when the water through the tube bundle heat exchanger tube surface evaporation, precipitation of calcium and magnesium deposition in the wall to form a hard scale layers, with the general approach to be ineffective, it must be such aschemical or mechanical cleaning methods.
Chemical cleaning is the use of cleaning agents and dirt layer from the chemical reaction method to remove the fouling, for more complex shape of the cleaningcomponents, such as the U-tube heat exchanger cleaning, pipe cleaning between.This cleaning method is that the metal has a slight corrosion injury. Mechanicalcleaning is the easiest blade, rotary wire brush to remove the hard dirt floor, coke or other deposits.

Temperature Problem of Heat Exchanger
Heat exchanger in the relative flow of fluid downstream and upstream are generally two. Downstream, the maximum temperature difference between the two fluids at the entrance and along the heat transfer surface, gradually reducing to a minimum temperature at the exit. Reflux, the two fluids along the heat transfer surface temperature distribution is uniform. In the cold and hot fluid inlet and outlet temperature under certain conditions, when the two fluids are no phase change, the maximum temperature difference in the average upstream downstream minimum.
Upon completion of the same heat transfer (Heat exchanger)conditions, using counter-current can increase the average temperature difference, heat exchanger heat transfer area is reduced; if the heat transfer area of the same, using reflux heating or cooling fluid can reduce consumption. The former can save equipment costs, which can save operating costs, it is used in the design or production should maximize the use of the countercurrent heat exchanger.
