Standard Economizers
1-6
Part No. 750-266
Do not insulate the exchanger where factory insulation has already been applied or damage to the
exchanger can occur. Insulate piping and exhaust ducting as required.
Ensure that no liquid connections interfere with the opening of access door panels.
For the CCE series exchangers it is recommended that the liquid flow connects into the top of the
economizer and out the bottom for cross flow. Consult the circulating flow diagram (if applicable) for
your application in regards to the piping layout and components. Exhaust and liquid inlet and outlet
thermometers (optional) may be included in the installation.
Economizer relief valves shall not have set pressure ratings higher than the rated pressure of the
economizer. Liquid storage tank relief valves shall not have discharge pressure ratings higher than the
rated pressure of the storage tank. To avoid safety valve leakage, ensure that safety valve set pressure
is sufficiently higher than dead head pressure of the feed pump.
It is recommended that the pipe and circulating tank (if included) be insulated to reduce heat loss.
If existing conditions may subject the fin tubing to internal scale build up, pressure gauges (furnished
by others) should be installed on the liquid inlet and outlet sides of the economizer. This will enable
monitoring of liquid flow restriction. Capped tees, one on the liquid inlet side and one on the liquid
outlet side, incorporated into the piping installation may allow a descaling solution to be used with the
economizer in place. Consult the factory for suitable descaling solutions.
Installations with a modulating feed valve are subject to pressure buildup in the economizer piping
when the feed valve is closed. Frequent overpressure can lead to overuse of the safety valves with
eventual valve failure. To avoid this condition, a bypass (recirculation) line should be installed as
shown in
