Bryan Boilers: EB

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 chamber. A high percentage of the heating surface is exposed to direct radiant heat, increasing water velocities and heat transfer.

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 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 considerable savings in building costs. Pressurized fi ring 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 fi re 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 directs 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 upward. This configuration, along with the large volume down-comer water legs, provides the extremely rapid natural thermal internal 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.
