Quiet Heaters, Sparger Nozzles, and Circulating Heaters are similar in that they are all classified as "open tank heaters".
Fig. 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.
Fig. 314 Sparger Nozzles are designed to be submerged in the liquid to be heated. Heaters of this type are recommended for use in cases where it is desired to start heating from a shallow level, where uniform agitation and heating is required over a large, shallow tank area, where steam pressures are low, and where solids in the liquid might tend to clog the small passages in other type heaters.
Fig. 315 Circulating Heaters are recommended for use where heating and strong directional circulating action in open tanks are required. This heater must be submerged in the liquid it heats. Only one pipe, for steam, is needed.
Fig. 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.
Fig. 314 Sparger Nozzles, because of their good agitating and circulating characteristics, can augment or replace mechanical agitators while enhancing heat transfer. Like other jet equipment, they are inexpensive and require little maintenance in comparison with the equipment they can replace. This is particularly noticeable in applications requiring special corrosion resistant materials.
Fig. 315 Circulating Heaters, because of their good agitating and circulating characteristics, can augment or replace mechanical agitators while enhancing heat transfer. Strong directional flow enables efficient heating of irregular tanks with dead spots that a resistance or bayonet heater cannot reach.
