Title:
The role of thermophoresis during deposit build-up on a superheater tube 
Abstract:
Most studies on modelling ash deposition in pulverised fuel boilers focus on inertial impaction as the main deposition mechanism. Effects, such as thermophoresis or heterogeneous condensation, are often neglected. However, there are several studies indicating that thermophoresis plays a key role during the early stages of deposit build-up on a superheater tube. Presented results obtained by numerical simulation show the dominant role of thermophoresis for small particle diameters, below 20 µm. I...    »
