1.4-STARTUP
During the initial startup and before combustion heat can be applied to the exchanger, ensure that
liquid is flowing through the economizer.
NOTE:
C-B requires that liquid must be flowing through the economizer at all times to avoid damage
to the exchanger from stack exhaust overheat.
Upon cold startup of a full boiler, provisions must be
made to ensure water flow through the economizer.
Assure sufficient flow to prevent any unwarranted
temperature and pressure buildup within the liquid side of the economizer. When the boiler reaches
the operating steam pressure of the system and begins to take on feedwater, normal operation can
resume.
If the final exhaust temperatures are too low, pressure drop across the economizer is too high, or if the
desired water temperature is not exceeded, adjust the gas bypass damper to attain the desired
objective.

Important
!
If liquid is introduced into a hot exchanger, severe damage can result and
will void any warranty. Contact C-B for applications where the exchanger
is requested to run dry.

Damper Closed
Damper Open
With the damper in the closed position, exhaust gas is diverted through the finned tubing, where heat exchange takes place.
When the damper is in the open position, exhaust gas bypasses the economizer tubes.
