Richard Winslow is a niche expert on power plant lubrication

Richard Winslow is a niche expert on power plant lubrication We first learned about Richard’s lubrication expertise in an article he wrote when he was with PacifiCorp. There was a pulverizer wear problem at the Naughton plant of Pacific Corp. An advanced filtration technology for the coal pulverizer was determined to be readily available for heavy gear oil that would meet solve the maintenance problems. An off-line kidney loop filtration package using a high-efficiency, high-dirt-holding capacity, synthetic filter media was solved the problem. Richard moved on from PacifiCorp and most recently has been in Alaska with ConocoPhillips. He has agreed to a niche expert role in our linkedin discussions and decision system. In addition to his Naughton paper we have also include his paper on minimizing bacterial contamination. His resume is attached.

Bacterial Contamination of Turbine and Circulating Lube Oil Systems

Bacterial contamination of large circulating oil systems in steam turbines is an expensive problem. This paper describes the problem and lists the types of lubricants and conditions that appear to be most susceptible, methods of treatment and known methods to clean up and prevent bacterial contamination.

Pacific Corp Naughton reduces pulverizer maintenance with new lubrication system

At the Naughton plant of Pacific Corp an advanced filtration technology for the coal pulverizer was determined to be readily available for heavy gear oil that would meet solve the maintenance problems. An off-line kidney loop filtration package using a high-efficiency, high-dirt-holding capacity, synthetic filter media was procured and installed. The package uses two filter housings mounted in series, with a common-sized element in both housings. The filter elements initially recommended for the trial installation were rated at Beta 25=200 in the first stage and Beta10=200 in the second stage. Oil flow was delivered by a vane pump rated at 10 gallons per minute for a 460 centistoke (cSt) (2,500 SUS) gear oil. Temperature ranges of the system fluid varied from a low of 65 degrees Fahrenheit (18 degrees Celsius) when idle, up to 130°F (54°C) during normal operation. The filtration package is installed with the suction line coming into the filter bank directly from the bottom of the reservoir; the outlet, or filtered discharge line, is piped directly into the top of the reservoir. The filter element condition is monitored by differential pressure gauges installed on each filter housing with a target of 25 to 28 psig as an indicator of element loading; the elements were changed out prior to allowing the internal bypass valve to begin opening. Other features of the filtration package include upstream and downstream sampling valves to allow gear oil samples to be taken without having to shut down the system.
