1.8.16 SPECIAL APPLICATIONS
FLUE GAS ECONOMIZERS
When applying flue gas economizers, care must be taken
to assure that:
1. Proper draft must be maintained. This requires that the
gas side pressure drop be considered and that the
economizer exchanger must be designed so as to allow
cleaning.
2. The vent system materials must be considered
regarding resistance from corrosion which might result
from the lower flue gas temperature.
3. In general, it is recommended that the boiler
manufacturer be consulted when a flue gas economizer is
to be added.
HIGH EFFICIENCY APPLIANCES
High efficiency appliances require special consideration in
vent design because of the reduced stack gas
temperatures. Under no circumstances can a condensing
type appliance be vented into the same vent system with
other appliances. The vent system for such appliances
must be provided by or specified specifically by the
manufacturer of the condensing appliance.
High efficiency non-condensing appliances should
generally be installed only on vent systems that are
resistant to corrosion from flue gas condensate. This
generally requires stainless steel vent construction.
