These heaters reduce the
viscosity of oil by pre-heating, thus facilitating withdrawal of oil
from bulk storage.
OPERATION:
Steam or hot water flows through the tubes while oil
flows outside the tubes, which are baffled to assure efficient
heating.
CONSTRUCTION: Heads are cast iron or steel. Tubes are heavy
gauge steel. Tube sheets and baffles are steel. Tube bundles are
removable. Heads are removable without emptying contents of tank.
A special M & L swing valve
is available which will permit closing off the shell of suction
heaters inside the oil tank so that the tube bundle can be
withdrawn, if required, without the necessity of first emptying the
tank.
ALTERNATE CAPACITIES-For
other oil heating ranges, use multipliers shown in the "Table of
Multipliers". As an example, the oil heating range in the "Table of
Capacities" is 20° to 100° F, when using steam at pressures shown.
If the oil, however, is to be heated from 40° to 120° F, instead of
20° to 100° F, multiply the capacity shown in the "Table of
Capacities" by multiplier 0.75, obtained from the "Table of
Multipliers", to arrive at the new capacity for the alternate
heating range.
