TIGHT CHAMBER OF A HEAT EXCHANGER WITH A MANTLE CONSISTING OF STRAIGHT WATER PIPES ARRANGED CONCENTRICALLY AROUND A CENTRAL BURNER

摘要

A gas-tight chamber for a heat exchanger has a shell (12) forming the gas-tight chamber made of a light flexible or semirigid material such as rubber or thin silicone-treated sheet material which, because of its low weight and relative flexibility, absorbs all the vibrations produced and maintained by the burners, which eliminates the noise. The exchangers have a layer of longitudinal water tubes arranged concentrically around a central burner.
