CONDENSER CLEANING SAVING $1 MILLION ANNUALLY

摘要

Omaha Public Power District's North Omaha Power Station has been operating on the west bank of the Missouri River for many years. The station has four coal-fired units with a total capacity of 600 MW. Although the station is primarily base-loaded, one or more units are sometimes assigned to load following. Originally designed to burn natural gas or high Btu Kansas coal, the units have been converted to bum Powder River Basin (PRB) coal. Like all power plants, a key contributor to the efficiency of the Omaha station's steam cycle are the condensers. The greater the condenser vacuum the higher the cycle efficiency. Poor condenser performance is one of the largest causes of lost efficiency in a power plant.
