Evaporative heating furnace - is based on use of evaporating material, e.g. sodium chloride, with b.pt above required furnace temp.

摘要

Furnace is used in the ferrous, non-ferrous and mechanical engineering industry for annealing, patenting and other heat treatment purposes. It is based on the use of an evaporating material with a b.pt. above the required furnace temp. The articles are heated by the latent heat released by the vapours which condense on them. The condensate is returned to the heated sump and a vacuum pump connection is cooled to condense escaping vapours. This furnace achieves a high heating rate without increase in the energy consumption and eliminates any possible oxidn. of the articles.
