FIG. H-20 Shop photograph of CSA-approved electric hot pipe tank heaters showing terminal boxes of explosion-proof Ex(d) design. Serrated fin tube outer pipes. The Internal heating eiements are removabie without draining tank. (Source Armstrong Engineering Associates.)... [Pg.406]

FIG. H-21 Suction-type heater, normally installed in tank side nozzle to heat up relatively larger flows of viscous materials using steam, hot water, or other heating fluid in the tubes. These heaters normally have low shell side pressure drops to minimize npsh problems on pumps. For very high viscosity fluids, consult the manufacturer for methods of reducing intake viscosity. An Internal shutoff valve can be used to allow easy bunde removal. Main uses of this type heater Include bunker C, fuel oils, asphalt, molasses, caustic, etc. (Source Armstrong Engineering Associates.)... [Pg.407]

FIG. H-22 Line-type heater. This Is simply a suction-type heater with an enclosed end so that the heater can be Installed outside the tank. This permits addition of an external valve between the tank and the heater to allow servicing of the heater without pumping down the tank. Basically, the incentive to use a line heater is either maintenance ease or piping simplicity. (Source Armstrong Engineering Associates.)... [Pg.407]

FIG. H-24 Coil-type stab-in tank heater. This type heater is installed through a side entering tank nozzle, and differs from the bayonet type in that usually more pipes or tubes than one are used, requiring therefore a tubesheet and bonnet, or a continuous coil to allow for usually lower flow of heating medium such as heat transfer oils, diphenyl, etc. Rns are helical for natural convec tion. (Source Armstrong Engineering Associates.)... [Pg.408]

HG. H-26 Horizontal in tank heater. This type heater has fins to allow good thermosiphon circulation of the fluid being heated, and gives a wide thermal current stimulation. Due to the compact surface, much larger amounts of heat can be added to the tank contents than when using bare tube coils of comparable area. (Source Armstrong Engineering Associates.)... [Pg.408]

FIG. H-27 Process-type heaters are available from 2 In (51 mm) to 48 In (1219 mm) shell diameter. Unit is 42 in (1066 mm) shell diameter. (Source Armstrong Engineering Associates.)... [Pg.409]

FIG. H-28 Bottom bundles are sheathed element heater. Liquid level of intermediate fluid is boiled by bottom bundle and then condenses on top bundle. Intermediate unit is used when pressure is very high or upper heating bundle Is of very costly metal to avoid hawing the whole unit of the costly metal or the high pressure design, which is thus confined only to the upper bundle.

FIG. H-34 Explosion-proof NEMA 7 or Ex(d) control panel. CSA-approved explosion-proof panels may be supplied on special order. Note heavy-duty bolted enclosure for internal explosion containment. (Source Armstrong Engineering Associates.)... [Pg.412]

FIG. H-37 Indirect fluid electric heater insulated and mounted on skid with all controls in place. One of several at the same site in South America. Capacity 24 kW (20,650 kcal/hr) vaporizing organic fluids. (Source Armstrong Engineering Associates.)... [Pg.414]

FIG. V-2 One of six all-stainless-steel vertical vaporizers for verticai iocation above tower in Mideastern refinery. Unit size 59 In (1500 mm) in diameter by 20 ft (6100 mm) high. (Source Armstrong Engineering Associates.)... [Pg.833]
