Boiling Tests of Thermal Insulation in Conduit-Type Underground Heat Distribution Systems

Source

Thermal insulation in a conduit-type underground heat distribution system is expected to withstand severe boiling, which can occur in the case of conduit failure under high groundwater table. The U.S. Government specifies boiling-test criteria for the approval of commercial underground systems. This paper describes the test apparatus and procedure of Tri-Services and Federal Agencies' Specifications in order to evaluate thermal performance of various insulations after they are subjected to prolonged boiling conditions.
