HTRI has conducted extensive testing on a spiral-spiral single-phase flow unit for a wide range of Reynolds (6.5 to 74,000) and Prandtl (3.8 to 2260) numbers. These data were used to evaluate open literature and HTRI methods.
The constant-speed approach to AC motors made a lot of sense when energy was cheap and drives technology was in its infancy. With their latest advances, adjustable speed drives can provide one of the best energy efficiency options for a plant.
The Alliance to Save Energy conducts ongoing research of the competitor within, a.k.a. organizational barriers to energy efficiency. The barriers to energy management are rooted in the very complexity of modern organizations. Communications and incentives are the key to overcoming these barriers.
Pneumatic conveying has long been a popular choice for moving bulk materials. However, the technology hasn't been standing still, and this can influence the choice between several types of pneumatic systems.
Variable speed drives offer the ability to monitor and reduce energy consumption, foresee line and motor problems and gain fine speed and torque control. Learn how to make your equipment dance with VSDs.
Installing an electric drive on a steam boiler damper results in lower fuel consumption. The reason? The electric drive enables boiler operation with just the right amount of excess air at lower firing rates.

Anywhere compressed air can be eliminated represents an opportunity to reduce system operating expenses. Often, this reduction means fewer compressors must operate to meet the plant's air requirements.
