Define Then Achieve Fleet Optimization

The term “optimization” has been used so much, for so many things, that by now it has almost no meaning.

Sonic Horns: A User’s Introduction

A sonic horn can get material flowing in your storage vessel or hopper truck or railcar by directing low-frequency sound vibrations into the vessel to fluidize stagnant material and buildup.

Interim Tier 4 Emissions Regulations for Generators

Keeping apprised of the U.S. Environmental Protection Agency’s (EPA’s) complex diesel emissions regulations can be a challenge, but now that these requirements encompass not only mobile off-highway applications but also stationary applications, it’s up to the generator owner/operator to stay informed.

Supplemental Pumps Pay Off During Low River Conditions

Low river levels are causing reliability problems with once-through circulating water pump systems at several coal-fired power generating plants sited along the Missouri and Mississippi rivers.

Ultra-Low NOX Burners Can Get Even Better

In the mid-1990s, a technology was developed that allowed burning natural gas in industrial boilers while producing nitrogen oxide (NOX) emissions less than nine parts per million by volume (ppm).

SCADA Systems: Unknown Connections Could Spell Trouble

The ease with which TCP/IP enables one to connect networks has been a huge boon for the power generation industry.

The Case for Using Reclaimed Water

If climate change is found to have significant impacts, one area may be in how precipitation changes will affect how much water is available for power production.

Designed-in Safety

As design engineers and architects, we have a tremendous opportunity to improve the quality of life in the communities in which we work and live.

Substratum Intake System: Once-Through Cooling Hybrid

Rising fuel cost, demand for carbon footprint reduction and closed-cycle cooling is simply incongruent.

Heat Exchanger Technology: The Advantages

For many of the new European supercritical coal-fired plants, builders are turning their attention to a heat exchanger technology that offers convincing technical and economic advantages over conventional U-type feedwater heaters.
