Abstract

This invention relates to a laboratory device which produces a fouling deposit, under controlled temperature and pressure, which reproduces actual plant conditions, and accurately measures the deposit of foulant accumulated during the deposition process. The device is utilized for testing the fouling tendencies of a wide variety of fluids which change on contact with a hotter surface, forming a solid or semisolid deposits which stick to the surface. The apparatus has the capability of calibration and measurement of the probe temperature and temperature measurement changes with fouling, and may be advantageously related to the amount of fouling present. The apparatus includes multiple probes each removably supporting test wires which are electrically heated to selected temperatures for simultaneous multiple fouling tests by a constant heat flux or to a constant temperature.
