Compressed Air Danger Points

Compressed air is one of the most common shop tools, yet one of the most dangerous. Improper use can maim, blind, or even kill. Always wear eye protection and use face shields when working with air tools. Danger Point – Accidental Hose Breach If a compressed air hose is breached, the escaping pressure snaps the […]

Crane Safety

When PSG begins planning for an outage, we ask the customer for a Crane Safety Report complying with OSHA Regulation 29 CFR 1910.179. This is an OSHA compliance issue that PSG feels is well warranted. First, we have a commitment to our employees to keep them safe from harm.   A crane malfunction can easily injure, […]

Gas Turbine Compressor Degradation

Contamination and Erosion All gas turbines experience losses in performance with time and the compressor has a significant impact. In a typical heavy duty axial compressor a 1.0% loss in compressor efficiency will create a 1.1% loss in output. Compressor fouling is a serious concern and can be mitigated or recovered through proper operational practices. […]

Seconds From Disaster – Overspeed Devices

A full loss of generator load can cause the operating speed of a turbine (steam or combustion) to go from normal to catastrophic in a matter of seconds. The electrical load can be lost from generator failure or from external sources such as hurricanes, floods or ice storms downing power lines. Basically, the generator load […]

Set IGVs for Maximum Efficiency

Have your combustion turbines been losing power after overhauls? There are many factors which can affect power production, but the IGV settings are one area that even the OEM can overlook. We recently helped a plant with three GE Frame 6B gas turbines that had lost power over successive overhauls. Units 1 and 2 had […]

Measure the Cause, Not the Symptom

Directly measuring bearing metal temperature is the most effective way to really determine if a bearing is running hot. Bearing oil drain temperatures are still being utilized on older machines. By the time the bearing oil drain temperature has increased, the bearing may have already been compromised (wiped). PSG recommends that these older machines should […]

The Ugly Effects of Water in Lube Oil

Free and emulsified water are the two most harmful conditions in a lubricating system. The incompressibility of water overrides the hydrodynamic oil film that protects bearings, leading to excessive wear. As little as one percent water in oil can reduce the life expectancy of a journal bearing by as much as 90 percent. Water will […]
