(3) Output and horsepower based on an average natural gas combustion efficiency of 84% for hot water boiler. Actual combustion efficiencies for oil will be higher.
(4) Lbs. steam per hour from and at 212°F.
K. Bryan bent water tubes
are flexible, individually re-
placeable without welding or
rolling. Never more than two
tube configurations.
L. Pressurized design firebox
with internal water-cooled
furnace with low heat release
rate.
M. Steam boilers with extra
large drum with high steam
release area ensure stable
water level and dry steam.
A. Water side or steam side interior ac cessible for
clean out and inspection, front and rear open ings,
upper and lower drums.
B. Large volume water leg down comers promote
rapid internal circulation, temperature equalization
and efficient heat transfer.
C. Boiler tube and furnace area access panels: heavy
gauge steel casing with 2" high-temperature ceramic
fiber insulation, bolted and tightly sealed to boiler frame.
D. Flame observation port in access door at rear of boiler.
E. Single side access; combustion chamber, tubes and burner
head are completely accessible from one side simplifying
maintenance and minimizing floor space.
F. Minimum sized flue vent.
G. Control panel: all controls installed with connections
to terminal strip.
H. Forced draft, flame retention head type burner. Efficient
combustion of oil or gas, plus quiet operation.
I. Heavy steel boiler frame, built and stamped in accordance
with the appropriate ASME Boiler Code.

Guaranteed efficiency and easy

All Bryan RV Series boilers offer these operating and performance features
Guaranteed efficiency
The breakthrough in water tube boiler design that pro-
duced the RV Series provides operating efficiency so
reliable, we guarantee it to be 84% for hot water boilers
and 82% - 15 psi / 80% - 150 psi or better for steam boilers.
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 configuration of the
water tubes provides a water
cooled combustion cham-
ber. A high percentage of
the heating surface is exposed to direct radiant heat,
increasing water velocities and heat transfer.
Large steam drum
The steam drum has generous 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
Inner panel provides easy and complete access to furnace
and boiler tube area, as well as to burner head. All panels
are heavily insulated and sealed to boiler frame. All access
is from only one side.
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, yet maintains
a full five square feet of heating surface area per HP.
Water Boiler
Combination thermometer and altitude
gauge, ASME Code rated boiler relief
valve, water temperature control (240°F
max std.), high limit control, probe
LWCO.
Steam Boiler
Steam pressure gauge, steam pres-
sure control, combination low water
cutoff and pump control, auxiliary low
water cutoff, high limit pressure
control, ASME-rated safety valve,
water glass set.
Straight gas fired 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
Needing only 32" for tube removal, and on only one side
of the boiler, the RV Series boiler occupies very little space
in the boiler room. This can result in considerable savings
in building costs. Pressurized firing permits minimum
sized breaching and vent.
Multi-pass flue gas travel
High velocity four-pass flue gas travel is obtained by a
unique baffling system. This contributes to maximum
fire side heat transfer and overall high boiler efficiencies.
Thermal blend water return
Bryan’s unique “thermal blend” return blends cold or
cooler return water with warmer boiler water abridging
it to design operating temperatures. An injector tube di-
rects the “mixed” water flow 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 configuration,
along with the large vol-
ume down-comer water
legs, provides the extremely
rapid natural thermal inter-
nal circulation, promoting
both high efficiency 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.
