Many customer quotation requests provide only the line size, pressure class rating, and valve type. A typical request might read: size 4, Class 900 globe valve. Though this may be enough information to produce a valve quote, it rarely is enough information to size the best valve from both a performance and cost perspective.

Once pulverized coal flows have been measured, they can be balanced and optimized. Until then, tuning is simply guesswork. The right way to balance furnace fuel flows is to establish solid baseline performance by proper measurement of fuel flow, fineness, and velocity. Only then can all the coal pipes be accurately balanced and followed by a tune-up of the boiler controls.

The design of Nash’s new ECO-FLO builds on the company’s previous liquid ring vacuum pump models. While it offers the same reliability, performance, and operating costs, the ECO-FLO reduces water usage by up to 50%. The inlet and discharge piping are unchanged, and the upgraded model uses an existing base, motor, and drive. ECO-FLO is […]

In this column last month I quoted Indian Environmental Minister Jairam Ramesh to represent India’s intention to not agree to any legally binding emissions targets at the Copenhagen Climate Change Conference in December. That conference will start formal negotiations of a follow-on agreement to the Kyoto Protocol. A number of readers wrote to say that they believe India and China, despite their protestations to the contrary, will cave to international pressure and at the end of the day agree to some binding carbon emissions limits. I disagree.

For some time, the U.S. energy industry has feared the prospect of large-scale climate change litigation (CCL) that seeks to link emissions of greenhouse gases (GHG) to global warming. Thus far though, only a handful of such suits have been filed, and none has yielded any judgments against the energy industry. This begs the question of whether the energy industry can now stop worrying about CCL.

E.H. Wach’s newly launched Small Diameter Split Frame (SDSF) is an externally mounted machine tool for cutting, beveling, and counterboring pipe from 0.84 inch to 4.5 inch diameter. Featuring a self-squaring clamping system for precise cutting results that are typically available only with fixed machine tools, the SDSF is also capable of performing socket weld […]
