Compact induced current heat-generating pipe

摘要

A compact induced heat-generating pipe useful for shorter bodies to be heated, such as small scale pipelines, the heat-generating pipe consisting of at least one set of two or three ferromagnetic pipes and an insulated wire passing therethrough and connected to an A.C. source, the respective pipes being electrically connected to each other at both the respective ends; thickness t of the pipes having a relationship of 0.5 s. ltoreq.t s, wherein s is the skin depth of A. C. flowing through the pipes; the pipes of each set being brought into close proximity to each other; and the length of the pipes being 1 Km or shorter.
