Layered storage tank with multiple feed pipe outlets joins horizontal leg of superposed angle outlets to pipe and vertical leg directed donwnwards into tank as fitted with base-level heat exchanger.

摘要

The superposed feed pipe (1) outlets (2) form two-leg angles having one leg horizontally joined to the pipe as opposed to the other leg which opens downwards directly into the storage tank (3). A heat exchanger inside or outside the tank lies below the feed pipe so the secondary circuit is produced by the rise of the heated water in the pipe and the heat exchanger operated by gravity. The exchanger is joined to the tank bottom and linked by secondary feed (4) to the foot of the feed pipe (1). Several feed pipes can be fitted with superposed outlets, each pipe and its outlets being a prefabricated unit, or again a single riser (1) can be used with its outlets made up of combinable modules. The heat exchanger has a cylindrical jacket and stands axially below the feed pipe (1).
