FIELD: electricity.SUBSTANCE: in coaxial heater consisting of an outer and inner tube, which are placed coaxially and insulated from each other at one end and contact with each other at the other end, the inner tube is perforated in its butt end. Electrical contact between tubes is realised by a perforated ring, and in the outer tube at distance of 0.2-0.5 of the outer tube diameter from the ring perforation is made.EFFECT: increased efficiency ratio of the coaxial heater.1 dwg |
