Abstract:
A fouling test unit comprising:an elongated flow tube;a fouling probe disposed within said flow tube, said fouling probe including a heated section;an annular passage defined between said fouling probe and said flow tube and extending from a fluid inlet to a fluid outlet, said passage adapted to have a fluid flow from said fluid inlet toward said fluid outlet;an impeller mounted within an enlarged section of said flow tube for inducing said fluid to flow within said annular passage from said fluid inlet toward said fluid outlet;a plurality of temperature responsive devices for monitoring a rate of heat transfer and a change in temperature of said fluid as said fluid flows through said annular passage, said plurality of temperature responsive devices including at least first and second temperature responsive devices disposed relative to said fouling probe for measuring the temperature of said fluid relative to said inlet and said fluid outlet; anda high pressure vessel enclosing said flow tube, said fouling probe and said impeller.
