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 ra-
diant heat, increasing 
water velocities and heat 
transfer.
Large steam drum
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 remov-
able, 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 con-
siderable savings in building costs. Pressurized fi ring 
permits minimum sized breaching and vent.
Water Boiler
Combination thermometer and alti-
tude gauge, ASME Code rated boiler 
relief valve, water temperature control 
(240°F max std.), high limit control, 
probe LWCO.
Steam Boiler
Combination low water cutoff and 
pump control, auxiliary low water cut-
off, high limit pressure control, ASME-
rated safety valve, water glass set.
Straight gas fi red unit
Electronic combustion safety control, 
automatic operating gas valve, safety 
gas valve, pilot solenoid valve, pilot 
ignition assembly, main manual gas 
shut-off valve, pilot cock, pilot and 
main gas pressure regulators, air safety 
switch, control panel, all controls 
installed and wired.
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 up-
ward. This confi guration, 
along with the large 
volume down-comer 
water legs, provides the 
extremely rapid natural 
thermal internal circu-
lation, promoting both 
high effi ciency of heat 
transfer and uniform 
temperature throughout 
the boiler. Eliminating 
stress damage caused 
by unequal temperature dis-
tribution is especially important 
for heating systems, particularly where 
intermittent or continuous low temperature water 
returns may be encountered.
