Overcoming the Challenges of Owning and Maintaining Legacy Instruments
by Jessica Drinnon Whether the instrument has been in service for many years or you just managed to purchase a gently used or refurbished instrument, considerable complications arise when you are notified that the manufacturer or calibration...
Elevating Industry Standards: The Crucial Role of RF Calibration
At McHale & Associates we understand that RF (Radio Frequency) technology is the backbone of numerous critical industries, from telecommunications to aerospace. As these sectors evolve, the demand for precision and reliability in RF equipment...
Characterization of Elliptical Pitot Tube for Water Flow Measurements (TP24-03)
ABSTRACT In 2018, CTI switched from simplex pitot tubes to an elliptical style pitot tubes for water flow measurements. This change was made to reduce the impact of change in Reynolds number on the calibration coefficient of the pitot tube....

A Real-Time Output-Loss Method for Monitoring Heat Rate for Coal-Fired Power Plants
ABSTRACT This paper describes a real-time performance monitoring method based on PTC 4-2013 for determining instantaneous heat rate for coal-fired power plants. The calculation protocol uses a modified output-loss approach applied to a control...
Exploring a Variant of PTC 4-2013 for Real-Time Performance Monitoring of Fossil Fuel Power Plants
ABSTRACT This paper describes a real-time performance monitoring method based on PTC 4-2013 that was developed for determining and reporting annual heat rate for fossil fuel power plants. Unlike for the PTC 4 test, the coal composition is typically...
A Modified F-Factor Approach for Real-Time Performance Monitoring of Fossil Fuel Power Plants
ABSTRACT This paper describes a modified F-factor approach for real-time performance monitoring of heat rate and CO2 emissions for fossil fuel power plants. The calculation protocol introduced in the present investigation is a modification of the...
Your Source for Formaldehyde Detection
Is your facility a major HAP source and has gas turbines added after January 14, 2003? If so, the US EPA is only giving you 180 days to conduct initial stack performance testing to demonstrate compliance with a formaldehyde standard.On March 9,...
Fixed Duct Burner Heat Input Approach for Combined Cycle Power Plant ASME PTC-46 Performance Testing
ABSTRACT Since its publication in 1996, ASME PTC 46 Performance Test Code on Overall Plant Performance has established itself as the premier test code for conducting overall plant performance within the power industry, especially for combined cycle...
