Bryan flexible water tube boilers are ideally suit...
Bryan flexible water tube boilers are ideally suited for both hot water and steam space heating systems as well as either high or low pressure process steam. In a range of sizes from 3,500,000 to 6,500,000 BTUH input, Bryan K series flexible tube boilers are ideal for many commercial, institutional and industrial applications. These include healthcare facilities; schools; apartments; churches; office buildings; correctional facilities; airports; sewage treatment plants; golf, tennis and fitness clubs. Hospitals, dairies, restaurants, laundries, dry cleaners, food processing, tire recapping and metal plating are just a few of the many applications. All Bryan boilers are built in accordance with the requirements of the ASME Boiler and Pressure Vessel Code.
Efficient “Flexible Water Tube” design
The Bryan bent water tube provides rapid internal circulation — for maximum heat transfer and operating efficiency.
Easily replaceable tubes
Tubes are easily removable and replaceable without welding or rolling. Requires little service space.
No “Thermal Shock”
The flexibility of the bent water tube design eliminates all possible damage from 'Thermal Shock' and from stresses caused by poor or unequal internal circulation. This is particularly important with forced hot water heating systems designed for higher temperatures and greater temperature drops.
Steam Boilers:
Steam release area
Large, full-size steam drum provides for dry steam and stable water level.
High or low pressure construction
Boiler is constructed as standard for 15 psi or 150 psi maximum working pressure. Also available for higher pressures to 300 psi.
Water Boilers:
High or low pressure construction
Boiler is constructed as standard for 160 psi maximum working pressure at 230°F operating temperature and 250°F design temperature. Also available for higher pressures to 250 psi, at 285°F operating temperature and 300°F design temperature.
Natural internal circulation
The water tube design and the large downcomer legs provide adequate internal circulation without concern over exterior pumping conditions. Low pressure drop through boiler.
Compact — minimum floor space
Requires less floor space than most boilers, and tubes can be removed and replaced from one side, further minimizing space needs. Shipped completely assembled and wired. Units can also be shipped 'Knocked Down' for on-site assembly.
Design and construction features that assure reliable performance
A. Heavy steel boiler frame, built and stamped in accordance with the ASME boiler code. Hot water boilers constructed as standard for operating pressures to 160 psi. Also available for higher operating pressures. Steam boilers constructed as standard for operating pressures of 15 psi or 150 psi. Also available for higher operating pressures. Large steam release area for dry steam.
B. Water leg downcomers to insure rapid internal circulation and temperature equalization.
C. Bryan flexible water tubes, easily replaceable, requiring no welding or rolling. Tubes installed from one side.
D. Boiler tube access panel bolted tightly and sealed to boiler frame. Constructed of 2' insul-wool high temperature insulation in steel framework. Tubes installed from one side for easy accessible service and inspection.
E. Boiler jacket, heavy gauge zinc coated, with attractive enamel finish. Boiler jacket insulated with 1½' fiberglass to insure cool jacket.
F. Atmospheric gas burner controls — alloy steel atmospheric burner. Quiet electric ignition and operation. No moving parts or complicated adjustments.
G. All controls, gauges, relief valve(s) are factory installed and wired and easily accessible for servicing.
H. Control panel: all controls installed and connected to terminal strip.
