CALCULATION OF SEDIMENT FORMATION ON FINNED HEAT EXCHANGER TUBES ON CONDENSATION OF A VAPOR–GAS MIXTURE WITH SOLID PARTICLES

A mathematical model of the process of deposition of solid particles on the outer surface of tubes of a fi nned heat exchanger on condensation of a vapor–gas mixture containing particles has been developed. The model is based on determining the temperature fi eld in a round fi n from a given distribution of sediment thickness. The proposed model makes it possible to evaluate the infl uence of design and thermal parameters on the heat fl ux removed by a round fi n to a cylindrical tube. The infl uence of changes in such parameters as the fi n thickness and thermal conductivity of the sediment layer on heat transfer was assessed
