Quiet Heaters

Principle of Operation of Quiet Heaters

Quiet Heaters are classified as “open tank heaters” and used to quietly heat, circulate and mix liquids in open tanks. These units can be made in a variety of castable materials to meet various corrosive conditions.

Figure 301 Quiet Heaters are designed to heat liquids in tanks by condensing steam in the liquid and by causing circulation of the steam-heated liquid within the tank. These heaters employ entrained atmospheric air to reduce the loud noise usually associated with the introduction of steam into cold liquids.

Figure 301 Quiet Heaters have a low initial cost, have no moving parts, are easy to install, require little or no maintenance, mix as well as heat, give complete heat exchange between steam and liquid, and are quiet in operation.

Usually, these heaters are placed near the tank bottom to obtain maximum circulation. Steam pressure must be high enough to overcome submergence, yet not so great that live steam escapes from the surface of the liquid. The steam pressure can be set by a valve in the steam supply line to provide the liquid temperature desired. The air line should be equipped with a valve at its inlet so that the air can be throttled if agitation is greater than required. Compressed air may be used if additional agitation is desired.
