Bryan K Series Boilers Standard and Optional Equipment
STANDARD EQUIPMENT
FURNISHED
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 operat-
ing pressures. Large steam release
area for dry steam.
B. Water leg downcomers to insure rapid
internal circulation and temperature
equalization.
