Caldwell applies wet compression technology to turbine

15 December 2008 — Caldwell Energy Co. said it successfully completed the first application of wet compression technology on a General Electric Frame 7EA Combustion Turbine.

The systems were installed on four GE Frame 7EA turbines for an east coast utility and are fully operational, according to a press release from Caldwell. The wet compression systems included evaporative cooling with fog.

The system results included more than 10 percent power gain, improved heat rate and a reduction in NOx emissions of nearly 50 percent. These results continue to support other documented cases that indicate wet compression technology improves operational flexibility while reducing emissions and fuel consumption, according to Caldwell.
