Boiler Technologies: Electric Boilers
 Because
there are no combustion considerations, an electric boiler
has minimal complexity (no fuels or fuel handling equipment)
with easily replaceable heating elements. An electric boiler
may be an alternative to supply low or high-pressure steam
or hot water where emission regulations restrict options or
where the cost of electric power is minimal.
Top
mount heaters with vertical elements are standard in steam
and water boiler designs. Water normally contains calcium
and magnesium salts in suspension. The solubility of these
chemicals decreases with increased temperature so that they
may precipitate out of the water when it is heated in a boiler.
With top mount (vertical elements), a water/water vapor "stack"
effect develops, creating a corresponding cleansing action
over the electric element. This design concept has proven
to minimize scale build-up on the heating element sheath,
which prolongs heater element life. Top mount elements also
simplify maintenance and save space. Unfortunately, with very
large boilers the top mount design becomes impractical.
