A Modern Gas Power Plant Thrives on Ancient Wisdom

Built and developed in accordance with the principles of vaastu shastra, this 1.5-GW “mega” gas power plant in India imbues positivity and proactivity into all aspects of plant operation. It has resulted

MPW Mobile Ultrafiltration and Demineralization Units Exceed Canadian Power Plant Expectations

Challenge:
After a major refurbishment, a Canadian nuclear plant required additional process and boiler feed water for plant start-up and commissioning.
The plant’s raw water supply contained measurements ranging from 1-10 NTU, conductivity from 70-100 and color units ranging from 180-420. The plant also experienced highly variable flow rates, ranging from 0-600 GPM, and issues with the

Best Practices for Welding Critical Power Plant Systems

Innovative welding techniques can produce consistently better-quality joints. Special alloys, appropriate pre- and post-weld heat treatment, and proper weld procedures can all help prevent catastrophic failure

What Is Meant by Power Factor?

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what affects
