Abstract
Heat transfer test assemblies for monitoring and recording fouling of aqueous systems are disclosed. The heat transfer test assemblies include an outer tube member, a heating rod positioned within the outer tube member, a ribbed tube sleeve fitted over the heating rod and thermocouples for sensing the wall temperature of heating rod. The disclosed heat transfer test assemblies enable improved monitoring of systems employing enhanced heat exchanger tubes. Monitoring and recording apparatuses including the heat transfer test assemblies are also disclosed.
Claims5
An apparatus for monitoring and recording fouling of an aqueous system comprising:
- (a) a piping assembly integrated or coupled with a monitoring and recording assembly;
- (b) a heat transfer test assembly comprising:
- (i) an outer tube member;
- (ii) a heating rod positioned coaxially within the outer tube member, said heating rod comprising means for sensing a wall temperature of said heating rod;
- (iii) a tube sleeve assembly coaxially fitted over the heating rod within the outer tube member,
- wherein said tube sleeve assembly comprises a ribbed sleeve section, an upstream flow transition section positioned upstream of and butted against an upstream end of the ribbed sleeve section, and a downstream flow transition section positioned downstream of and butted against a downstream end of the ribbed sleeve section;
- and
- (iv) an annular fluid flow passageway disposed between the tube sleeve assembly and the outer tube member
- wherein the heat transfer test assembly is disposed within the piping assembly;
- and
- (c) an additional heat transfer test assembly disposed within the additional heat transfer test assembly comprising:
- (i) an additional outer tube member;
- (ii) an additional heating rod positioned coaxially within the outer tube member, said additional heating rod comprising means for sensing a wall temperature of said additional rod, wherein said additional heating rod comprises a smooth outer surface;
- and
- (iv) an annular fluid flow passageway disposed between the additional heating rod and the outer tube member.
