Savchenko V. Heat transfer of plate heat exchanger working at heat exchange surface contamination.

Dissertation is devoted development of theoretical positions and practical recommendations for maintenance of peri-calculated value of heat transfer at contamination of heat exchange surface of working plate heat exchanger. Two-parametric dependence of deposits layer thickness for plate heat exchanger is firstly received subject to work time and coolant speed in the range of speeds 0,1-1,0 m/s. Heat-exchange apparatus classification is got further development on characteristics determinative of heat exchange surface contamination. Approach to heat transfer determination of working plate heat-exchange apparatus is developed on the basis of application of deposits layer thickness dependence from time and parametric researches using of Bio criterion. The theory of reliability for heat-exchange apparatus, based on the presented concept of functional reliability subject to formation of deposits on a heat transfer surface, is got further development.
