EFFECTS OF FOULING AND OPERATIONAL CONDITIONS IN PRE-HEAT TRAIN HEAT EXCHANGERS DESIGN

Fouling in Heat Exchangers

Analysis of Fouling in HVAC Heat Exchangers by CFD

The purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by CFD analysis. First the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. Then the gas side properties and flow parameters were solved by ANSYS Fluent 14.5 software. Lagrangian equa...

Fouling of Heat Exchangers by Dairy Liquids

Fouling of Heat Exchangers in the Dairy Industry

J. Visser Th. J. M. Jeurnink NIZO, 6710 BA Ede, Netherlands N A general overview is given of the main factors in the fouling of processing equipment used for heating dairy fluids. The data collected indicate that the primary step in fouling is the adsorption of a monolayer of proteins onto the wall of the heating equipment at room temperature. Real fouling (i.e., the formation of macroscopic la...

Detection of Fouling in Heat Exchangers using Model Comparison

Fouling of heat exchangers is a severe problem in the industrialized world. The effects of fouling are reduced energy efficiency and increased greenhouse gas emissions. In fact, any heat transfer process has a risk of fouling on the heat transfer surface. The fouling can in some cases be cleaned physically, chemically or burned off; in other cases it may not be possible to clean the heat exchan...
