The Hartford loop is a special arrangement of return piping at the boiler. Its purpose is to reduce the likelihood of an insignificant quantity of water creating a low water condition that can cause damage to a steam heating boiler. It came into general use in 1919 and was primarily designed for use with heating systems having gravity wet return. In effect, it consists of two loops of pipe forming two U-tubes. The first loop is around the boiler and the second loop is composed of the drip connection, the wet return, and a short riser called the loop riser.... The use of a Hartford loop is not recommended where the condensate is returned to the boiler by a condensate pump.  2, fiche 1, Anglais, - Hartford%20loop

The steam heating system conveys steam through pipes to heat exchangers, such as radiators, convectors, baseboard units, radiant panels, fan-driven heaters, and returns the resulting condensed water to the boiler. Such systems normally operate at pressure not exceeding 15 pounds per square inch gage(psig) or 103 kPa gage, and in many designs the condensed steam returns in the boiler by gravity because of the static head of water in the return piping.  3, fiche 3, Anglais, - condensed%20water

The operating principle of pressure screens is similar to gravity centrifugal screens. The distinction is that they operate under full line pressure and the radial flow within the unit can be either centrifugal(outward), centripetal(inward) or a combination depending on design. They have the advantage of high capacity per unit, flexibility of physical location, small space requirements and economy of piping and pumping. The totally enclosed design excludes air entrainment and minimizes slime buildup.  2, fiche 8, Anglais, - pressure%20screen
