Abstract
A fouling test apparatus comprising a cylindrical pressure vessel, means for controlling the temperature of fluid contained in the vessel, cylindrical probe having a metallic surface concentric with the vessel walls and provided with a heater for such surface; stirrer in the form of a rotor open at at least one end and positioned between and concentric with the vessel walls and the probe, and sensor for measuring the temperature of the fluid contained in the vessel and the temperature of the probe surface. The probe simulates a heat exchanger surface exposed to a fouling liquid medium. Deposits accumulate on the heated surface in a similar fashion to an actual system and the parameters which affect fouling are all represented. The probe operates with a constant heat flux. As deposits accumulate, the surface temperature of the probe increases and is used as a measure of the deposit formation. The probe is maintained in a stationary position and the stirrer is not dependent on an electrical feed-through.
