Condensing Economizers
2-30 Part No. 750-266
exit temperature is lower than normal, then either the heat transfer surface is fouled or scaled on the
inside of the tubing. This requires cleaning as soon as possible during a convenient shut down period.
In a circulating system containing a pump and BTU storage tank, if the economizer pressure relief valve
discharges, it is likely that there is no or little liquid circulating through the economizer. Check the
pump operation and repair or replace as necessary. DO NOT ATTEMPT TO REMOVE OR REPLACE
THE PUMP UNLESS THE PUMP, PIPES AND LIQUID HAVE BEEN ALLOWED TO COOL. You may also
need to check for flow restrictions in the piping and/or the economizer.
If the economizer liquid and outlet temperatures are approaching being equal as compared to the
original data, this may be a pump problem and/or a scale accumulation occurrence in the finned
tubing. Remedy as indicated above. It is also possible that the fin coils are severely fouled. Refer to
section 2.6
for cleaning.
2.7-MAINTENANCE
C-B condensing economizers are virtually maintenance free. Nevertheless, periodic inspections will
ensure trouble-free operation and long equipment life.
A routine physical inspection of the heat transfer core area will depend on the conditions of
temperature and the quality of combustion within the flue gas stream.
NOTE: Ensure that the
combustion source is off and is cool, and that the economizer is cool before attempting to inspect or
clean the fin coils.
With clean exhaust conditions, physical inspection will be
minimal if proper combustion at the heat source is maintained
The inspection and maintenance procedure can be performed
without dismantling any of the piping or the stack connections.
Two removable panels on the C2X allow inspection of the 1st
and 2nd stage fintube sections. A hinged access door is provided
on C2X and C1X models for inspection, cleaning, or removal of
tubes. Tube sections are individually connected by compression
fittings to the header manifolds.
The following is the procedure for opening and closing the
hinged door.
NOTE: it may be necessary to provide a means of
supporting the weight of the door.
1. Remove all nuts from the door flange studs, except one located
opposite the hinges.
2. Loosen all hinge nuts.
3. Pull hinge side of door all the way out to where the hinge slots stop at the studs and retighten hinge
nuts.8.
4. Remove the last nut opposite the hinge side.
5.Pull door out until adjusting bolt hits stop. The door should be out past the bolts.
6. Lower adjusting bolt until door hangs freely and adjusting bolt clearsstop.
7. Door is ready to open.
8. Reverse steps to close.
