Furnace for firing wire-like products

摘要

A furnace for firing an enamel-insulated wire comprising a principal chamber, an auxiliary unit for withdrawing a first stream of air and solvent vapors from this principal chamber for effecting combustion of the vapors themselves. A part of a second stream leaving the auxiliary unit is mixed with a volume of air at ambient temperature and passed to the principal chamber; another part is sent to a heat exchanger in which it gives up part of its thermal energy to a second volume of air at ambient temperature which is heated and introduced into the principal chamber.
