Plant Rolls In Replacement During Maintenance Outage

摘要

Replacement of a piece of major equipment can take a big bite out of a powerplant's revenue, as the plant must be offline for the work to be done. But a Midwest utility completed demolition and replacement of one electrostatic precipitator in 10 weeks this spring and plans to repeat the operation next year. "The key driver for (replacing) the precipitators was the physical degradation from 35 years of operating experience," says Terry Ward, project manager for Cincinnati-based Cinergy Corp., the parent of PSI Energy Inc., which owns and operates Cayuga Generating Station, Cayuga, Ind. Ward anticipates stricter federal or state opacity regulations. The new precipitators remove 99% of partic-ulate matter and exceed state permit opacity requirements by 50%, he says.
