Efficient “Flexible Water Tube” design assures
easy maintenance and low cost operation
All Bryan EB Series boilers offer these operating and performance features
The Bryan Flexible Tube
Multi-pass flue gas travel
Bryan’s exclusive “Flexible Tube” design eliminates the
possibility of damage from so-called “thermal shock.”
Tubes are easily removable and replaceable, without
welding or rolling, eliminating long, expensive downtime
should repairs ever be required.
High velocity four-pass flue gas travel is obtained by a
unique baffling system. This contributes to maximum
fire side heat transfer and overall boiler efficiency.
Thermal blend water return
Bryan’s unique “thermal blend” return blends cold or
cooler return water with warmer boiler water blending
it to design operating temperatures. An injector tube

possibility of “cold spots” and damage from corrosive

Water cooled furnace
The configuration of the water tubes
provides a water cooled
combustion chamber.
A high percentage of
the heating surface is
exposed to direct ra-
diant heat, increasing
water velocities and heat
transfer.

the boiler. Eliminating
stress damage caused
byunequaltemperaturedis-
tribution is especially important
for heating systems, particularly where
intermittent or continuous low temperature water
returns may be encountered.
Compact design, minimum floor space
With our compact water tube design, the overall size
of the unit is less than most other types of boilers.
Needing only 32" for tube removal, and on only one
side of the boiler, the EB Series boiler occupies very
little space in the boiler room. This can result in con-
siderable savings in building costs. Pressurized firing
permits minimum sized breaching and vent.
