The Practical Application SF6 and Helium Condenser Tube and Air In-leakage Detection


Many different methods are available for the detection of condenser tube and air in leakage. Once detected, it is necessary to locate the actual source of the problem so that it can be rectified and the health of the unit restored. The nature and severity of the leak largely determine the best method to be employed in locating its source.

The tracer gas technique has eliminated much of the guess work normally experienced when using less sophisticated methods, has resulted in less down time to perform leak detection, and has especially helped to reduce the increase in heat rate which is associated with air in leakage.

This paper presents the practical application and use of tracer gases to perform leak detection, compares this method with other techniques, and outlines the key elements which an engineer should consider when determining the most appropriate procedure and tracer gas to use in a given application.

Understanding Natural Gas Fuel Reliablity for Backup Power


Reliability of fuel supply tends to be of great concern for authorities having jurisdiction (AHJs). On-site fuel (most often diesel) is typically required for life-safety applications, and many mission-critical applications like 911 call centers specify it because it is perceived to be more reliable. Nonetheless, maintenance issues and delivery concerns of diesel fuel in an emergency, combined with the reliability and cost-effectiveness of natural gas, must be considered in a standby power system. NFPA and NEC offer provisions for the use of natural gas in standby power applications that had previously been the clear domain of diesel-fueled systems. There are also many ways to work with the AHJ to clear the way for the use of gaseous fuel in a standby power system.

Liquid Fuel Check Valve Operation In Gas Turbine Applications


Liquid fuel check valve operation in dual fuel gas turbine applications is extremely severe. The impact of both system and environmental related anomalies on liquid fuel check valves lead to both premature failures of the valve and other fuel system components
The development and use of water cooled liquid fuel check valves has shown that gas turbine owners can operate liquid fuel systems reliably for extended periods of time.

Top 6 places to look for energy losses in commercial buildings. A typical scan can show energy saving opportunities of up to 15%


Small, consistent changes can make a big difference in the profitability of any facility. Find problems fast, fix them, and win by realizing the cost savings.

Unlike regular digital cameras that capture images of the visible light reflected by objects, thermal imagers create pictures by detecting infrared energy or heat. The thermal imager then assigns colors based on the temperature differences it detects. With a small amount of training, most people can readily spot abnormal heat flow patterns and follow the heat trail to energy waste. The technique works best when used by people who already possess a good working
knowledge of the structures and systems being scanned and can better interpret the temperature variances they see on camera. A typical scan can show energy saving opportunities of up to 15 percent, with varying degrees of repair investments.

Thermal imagers have come down so far in price that most facilities can recoup the cost of purchase in terms of energy savings within six months. Plus, incorporating infrared inspection into regular maintenance provides significant efficiencies to a maintenance team as well as helping them identify and prevent expensive failures.

Forced Circulation Steam Generators for SAGD Applications


Steam-Assisted Gravity Drainage, better known as SAGD, is considered to be the most viable and environmentally safe recovery technology for extracting heavy oil and bitumen. The process, which has been utilized for more than a decade, uses an advanced form of steam stimulation to extract oil from a pair of horizontal wells drilled into a rservoir.
