Condensing Economizers
2-2
Part No. 750-266
2.1-GENERAL
The C-B condensing economizers are essentially static reactive type heat exchangers. 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 units are virtually maintenance free, having no moving parts except the internal gas bypass
assembly.
Each economizer includes 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 according to
performance requirements.

The C2X condensing economizer consists of two sections - the upper section for preheating incoming
boiler feedwater before it goes to the deaerator, and a lower section for further heating of the feedwater
after it leaves the deaerator.
The C1X (or the C2X upper stage) can also be used to heat any other liquid besides boiler feedwater.
By matching the economizer with the appropriate motor and combustion air fan, fuel-to-steam
efficiencies of over 90% can be reached.
2.2-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.
