A. GENERAL
Firetube boilers are available for low or high pressure steam, or for
hot water applications. Firetube boilers are typically used for
applications ranging from 15 to 800 horsepower. A firetube boiler
is a cylindrical vessel, with horizontal tubes passing through and
connected to the front and rear tube sheets. The vessel contains the
water and absorbs the energy generated from the flame. The front
door and rear door provide the seal to contain the hot combustion
gasses. Baffles designed into the doors serve to redirect the
combustion gasses through the various firetube passages. The
flame originates in the furnace. As the combustion gasses travel
down the furnace and through the various firetube channels, heat
from the flame and combustion gasses is transferred to the water.
Transferred energy develops into the required steam or hot water.
The primary purpose of the boiler is to supply energy to the facility’s
operations - for heat, manufacturing process, laundry, kitchen, etc.
The nature of the facility’s operation will dictate whether a steam or
hot water boiler should be used.
Notice
If your boiler is equipped with a C-B Hawk ICS boiler control
system, refer to C-B Manual No. 750-229 for information regarding
the control system.
