The method, heating system and heat exchanger for heating of sauna cabins and the steam generator for sauna cabins

摘要

Heating medium with b.p. of (180) deg. C. is heated to (150) deg. C. in a central heater (6) to transfer part of its heat to heaters (20,21) or steam-raisers (22) fitted into the sauna cabins (2-4) in a circuit (9-19) leading back to the central heater (6). Using heating oil as medium, this is preheated to feed temperature of (250-300) deg. C. using a heating oil boiler (6) as central heater connected via branch pipes (16-18) to the cabin heaters (20-23), each branch pref. fitted with its own feed temperature regulator (26,28,29). A second circuit for e.g. changing rooms can be coupled to the first circuit (9-19) via one or more heat exchangers (30), e.g. to produce hot water for showers (34). Straight, mutually parallel pipes are held at both ends in perforated plates formed by rear and front into a chimney figure.
