BRYAN BOILERS  
Originators of the “Flexible Water Tube” design  
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  
condensation.  
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.

Accessibility of furnace and tube area  
transfer and uniform  
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 remov-  
able, and all panels are heavily insulated and sealed to  
boiler frame. All access is from only one side.  
temperature throughout  
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.
