The Rewards of Pump System Optimization
Typically, when talk turns to power plant pumps, boiler feed and cooling water pumps immediately dominate the discussion. And that’s as it should be: these pumps are critical to a plant’s thermal efficiency and availability. They are also the most costly to produce, operate and maintain, so optimizing their efficiency is imperative. However, in terms of reliability and profitability for the entire plant, it is also prudent (and economically rewarding) to optimize pump system performance throughout the entire station.

Flowserve Boiler Feedwater pumps have beneficial features
This brochure describes pumps offered by Flowserve for combined cycle applications. Flowserve models DMX and WXH are commonly used for boiler feedwater to handle high pressures and fairly high flow rates. Flowserve models APKD and VPC are commonly used for condensate services.

VFDs can make a big difference in optimizing pump energy consumption in cooling tower makeup
William Livoti writing in “Empowering Pumps" discusses some of the potential regulations which will force recycling of cooling water. He says that power plants need to assess their pump requirements and consider variable speed drives to reduce energy consumption. He cites the advantages when handling off peak loads. A specific example is given for the VFD saving with cooling water makeup pumps

Buffalo Pump Explains Lubrication Evolution to 7F Users
A 2007 design upgrade switched the thrust-bearing lubricant from grease to oil, supplied via a connection on the pump discharge, thereby extending the bearing replacement time to 30,000 hours.

Tenaska Lindsay Hill Generating Station Ammonia Pump Problem
The facility’s anhydrous-ammonia forwarding pumps did not allow for double-valve isolation during maintenance. These pumps are only required for use on very cold days. This requires additional maintenance and laying them up for periods of non-use. The system had single-valve isolation from the ammonia storage tank to the suction of the pumps, a potential safety risk for the O&M team.Solution. Plant management decided to install double-block-and-bleed capabilities to the liquid suction line from the storage tank and liquid return line to the storage tank
