Cleaver-Brooks C1X Series, Operation Manual

Standard Economizers

1-2

Part No. 750-266

1.1-GENERAL

The Cleaver-Brooks economizer is essentially a static reactive type heat exchanger.  The performance
of this type of exchanger is ultimately dependent upon the dynamic conditions of temperature,
pressure and mass or flow available on both the liquid and gas side.

The C-B economizer exchangers are virtually maintenance free because they have no moving parts
except the movement of internal gas bypass assembly or the optional timed automatic soot blower.

Model CRE exchangers are equipped with a divertor plate and all exchangers include the C-B exclusive
internal stainless steel by-pass damper to divert the waste heat through the fin tubing or bypass a
portion up through the center or modulate (with optional equipment) according to performance
requirements.

Computer performance estimates are calculated on the basis that the damper is adjusted in the fully
closed position or perpendicular to the exhaust flow.

1.2-UNLOADING

Prior to manufacture all exchangers were represented with the issuance of an AutoCAD drawing to
scale for customer approval. This drawing can be used to prepare for installation and provide for
special equipment movement needs.

Cleaver Brooks inspects all equipment prior to shipment and cannot be held responsible for damage
caused in transit. In addition, all electrical devices are also thoroughly tested to assure that they
operate according to design specifications.

All exchangers are shipped via common carrier. Take care to inspect the heat exchanger when you
receive it and make any claims for damages immediately to the carrier within the allowable time limit. 

The CCE product line units are shipped in enclosed crates. To remove the economizer, first position
the unit, while either still in the shipping container or on the skid, as close to the installation site as
possible. Then attach a lifting hoist to all the lifting lugs located on the top lid or cone.

The CRE economizer is generally shipped in the position it is designed to be installed in. Depending
on size, some exchangers are shipped on wooden pallets and/or mounted on structural steel skid for
fork lift removal and/or installation. The very large exchangers if installed in the vertical position are
shipped on the side. Use all lifting lugs when lifting. To remove a large exchanger from the flat bed,
attach a lifting hoist to all the lifting lugs as required when lifting from horizontal to the vertical
position. For the extremely large heat exchangers be sure to have an experienced crane operator(s) for
removal from the flat bed and positioning. If there are any questions during the removal and
installation of the exchanger please do not hesitate to contact your authorized Cleaver-Brooks
representative for suggestions. Large exchangers include structural steel supports for mounting to the
final support (supplied by others) as required by the installation.

NOTE:

Spare parts may be shipped within the crate or skid mounted unit. Spare parts shipped within

the unit will be located beneath the damper bypass assembly in a separate shipping box.

To avoid delays in moving the economizer into position, have a fork lift and scaffolding ready prior to
receipt of the unit.

1.3-INSTALLATION

Consult submittal data for specific weights and dimensions to ensure a well designed and safe
installation when either hanging or supporting the exchanger.
