Extend EOH tracking to the entire plant

Predicting combined-cycle system longevity and determining optimal maintenance intervals at the same time is difficult: It requires balancing repair costs against the risk of trying to squeeze that last bit of life out of some component before it fails. One solution to the problem is to extend coverage of an equivalent operating hours (EOH) preventive management program for turbines to the entire plant.

Desuperheating valves take the heat

Hot reheat steam bypass actuators are some of the most critical, yet least understood components in a typical combined-cycle plant. If you’re using pneumatic actuators to stroke your main steam or hot reheat bypass valves in a cascading bypass system, you’re behind the times. Here’s a way to get better control of the bypass process, shorten unit start-up and train blending times, and decrease your plant’s heat rate—all at the same time.

How to make a power plant a welcome neighbor

Developing power projects has become less a technical challenge and more an exercise in developing good relationships among all the stakeholders. If a community understands the need for a new plant and is involved in its development process, the odds of a successful project increase.

The case for cathodic protection

All fossil fuels carry some risk with their reward of an energy density that’s sufficient for producing electricity economically. For coal and natural gas, that threat is a fire or explosion. However, the risk of an explosion isn’t limited to gas-fired plants. Gas poses a threat to any plant that uses the fuel, even in small quantities for heating. Here’s an overview of what you should be doing to keep gas pipelines from corroding and exploding.

Greater fuel diversity needed to meet growing U.S. electricity demand

Industrial Info Resources’ strengths are tracking capital projects and cost projections and providing intelligence about the power generation market, among others. IIR has used its large industry databases and numerous industry contacts to develop its outlook for 2008. Here’s what you should expect and plan for this year.

Regulatory risks paralyzing power industry while demand grows

In our second annual report on the state and future of the U.S. power generation industry, we combine the considerable experience of POWER’s editorial staff with the market savvy of Industrial Info Resources Inc. (see next story) to preview the industry’s direction in 2008. We anticipate that the specter of carbon control legislation will hobble coal and make renewables the hot ticket while nukes continue to inch forward in a generation market that is basically treading water.
