Effi cient “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
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.
Water cooled furnace
The confi guration of the water tubes
provides a water cooled
combustion chamber.
A high percentage of
the heating surface is
exposed to direct radiant heat, increasing
water velocities and heat
transfer.
Large steam drum
Water
Boiler
The steam drum has gen-
erous water volume and
steam release area. This
design, along with effective drum internal functions,
results in a stable water level and produces extremely
dry steam at all load conditions.
Accessibility of furnace and tube area
One hinged inner panel provides easy and complete
access to furnace and boiler tube area, as well as to
burner head. Other tube side panels are also removable, and all panels are heavily insulated and sealed to
boiler frame. All access is from only one side.
Compact design, minimum fl oor 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 considerable savings in building costs. Pressurized fi ring
permits minimum sized breaching and vent.
Multi-pass fl ue gas travel
High velocity four-pass fl ue gas travel is obtained by a
unique baffl ing system. This contributes to maximum
fi re side heat transfer and overall boiler effi ciency.
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
directs the “mixed” water fl ow through the downcomer to
the lower header and heating surfaces at a temperature
above possible condensing conditions. This reduces the
possibility of “cold spots” and damage from corrosive
condensation.
Positive internal circulation
Each pass of the Bryan
water tube slopes upward. This confi guration,
Steam
Boiler
along with the large
volume down-comer
water legs, provides the
extremely rapid natural
thermal internal circulation, promoting both
high effi ciency of heat
transfer and uniform
temperature throughout
the boiler. Eliminating
stress damage caused
by unequal temperature distribution is especially important
for heating systems, particularly where
intermittent or continuous low temperature water
returns may be encountered.
