Jan 01, 2013 · 4.1. Introduction. Ohio Power's 125-MW Philo Unit 6 entered service in 1957 becoming the world's first operating supercritical* power plant and incorporated double-reheat steam conditions of 314 bar/621 °C/566 °C/538 °C (4550 psia/1150 °F/1050 °F/1000 °F). The boiler † was supplied by Babcock & Wilcox and the turbine by General Electric (GE) and …

The frequency with which these bearings are replaced/reworked can be greatly reduced if proper attention is given to turbine lube oil contamination levels. Particulate contamination is a major cause of wear and premature failure of bearings.

Read MoreThe nuclear power generation has its own unique demands. Requirements for high purity water are substantially reduced when using gas turbines. However, the combined cycle operation incorporating both a gas turbine and a steam turbine still requires approximately 10 percent of the high purity water required for steam boilers.
Read MoreIn low-pressure boilers, pH measurement is fairly straightforward, but in high-pressure boilers requiring high-purity, low-conductivity water, pH measurement is, in short, a pain. A recent article by Michael Francis in POWER magazine explains why this is true and how you can overcome these challenges.

Read MoreDeionization (Boiler Feed Water) Diaphragm Valve. Deionization (DI) is the removal of all ionized minerals and salts (both organic and inorganic) from a solution through the process of ion exchange. Because most non-particulate water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled
Read MoreCaustic embrittlement can be prevented in a high-pressure boiler by coordinated pH-phosphate control. With this treatment the pH value of the boiler water must never be higher than the pH of a trisodium phosphate solution containing the same quantity of P0 4• 3-36. Colorimetric Test for Orthophosphate.
