The POWER Interview – Keeping Nuclear Power Viable

Nuclear power in the U.S. and globally has battled headwinds in recent years, and not just from the growth of other power generation resources such as solar, wind, and natural gas. Problems in the U.S. nuclear sector, such as construction delays and cost overruns at the Vogtle site in Georgia, the cancellation of the V.C. […]

Proper Valve Trim Extends Life of Boiler Feedwater Valves

Boiler feedwater valves operate under severe service conditions and are subject to premature failure from seat leakage, cavitation, particulates, and frequent cycling. However, once the type and root cause of

Controlling Boiler Level When Operating Conditions Change

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve heat rate

The Line Blurs Between Small Cogen Plants and Large Combined Cycles

When U.S. President Jimmy Carter signed into law the Public Utility Regulatory Policies Act of 1978 (PURPA), he unintentionally ignited the worldwide deregulation of electricity markets, which in turn began a worldwide technology race between two distinct types of power plants: the newly created, industrial-scale plant that PURPA dubbed “cogeneration” and the traditional, utility-scale power […]

Combined Heat and Power: A Sleeping Giant May Be Waking

One of the oldest energy efficiency ideas—combined heat and power—is prospering in the U.S. and looks promising elsewhere as the world searches for low-cost energy by increasing efficiency while lowering
