Gut Rehab Turns South Jersey Cogen Plant into Electricity Market Gem
Five years of essentially no maintenance investment or capital improvement at the Eagle Point Power Generation facility in Westville, NJ, had clearly taken its toll by the time Rockland Capital acquired the facility in April 2012. Today, Eagle Point expects the plant capacity factor to approach 50% once the last of the capital improvements are finished. Those improvements include everything from a punch list of 146 maintenance activities as well as capital upgrades, including a new steam turbine/generator, wet compression and fogging, and a complete gas turbine optimization and augmentation package which helped avoid the $11-million cost of an SCR.

How to Boost HRSG Performance and Increase Your Plant’s Bottom Line
The performance thieves lurking in many heat-recovery steam generators sometimes can be eliminated with relatively little effort and at low cost. This article discusses four primary performance thieves: Gas baffling, Gas-side fouling, LP economizer recirculation and Buoyancy instability/vapor locking.

Are Flexible Generation Plants Performing as Expected?
This article reviews the performance of the Siemens Flex-Plant installed at the Lodi Energy Center in Lodi, California. Designed to be highly flexible, fast-ramping and fast-cycling to complement renewable power generation, the facility experienced 380 starts over the two-plus year period from November 2012 to January 2015. The consensus is that the facility has lived up to expectations, although operational and maintenance costs are higher than for a typical combined cycle plant.

Quickly Boost Your Combustion Turbine Response
PowerPhase LLC has developed a new technology called TurboPHASE, a fast-responding, modular “turbocharger,” that can boost the capacity of an existing simple cycle or combined cycle plant by 10% or more in seconds. The system consists of a compressor that delivers hot compressed air to the discharge section of a combustion turbine, thereby allowing it to operate at the rated capacity irrespective of ambient air temperatures. Morris Cogeneration, a combined cycle cogeneration plant near Chicago, installed TurboPHASE, to boost capacity when needed during cold weather events.

Bulletin by Camfil outlines the definition of a HEPA filter. In order to meet industry practices and standards, every HEPA filter must be tested after all components are assembled. Camfil also tests the media upon factory arrival for conformance to specifications.

Engineered solution improves SCR performance significantly
Getting gas-turbine inlet air and exhaust gas to flow where and how you want it to in powerplant ductwork is akin to herding cats. The problem, as described by industry veterans Jim Carlton, president, Granite Ridge Energy LLC, and Larry Hawk, plant engineer, Granite Ridge Energy, operated by NAES Corp, was that the plant had been challenged by an underperforming NOx catalyst since commissioning. However, routine destructive sampling of the catalyst showed reactivity at or above expectations. And testing confirmed that the ammonia injection grid was properly balanced. What to do?

How to Reduce Catalyst Lifecycle Cost, Improve Reliability
Balancing the requirements of each SCR system in the fleet can be challenging. A system can reduce NOx by greater than 95%, but when the efficiency of the SCR is pushed beyond 85% and—or, if—the outlet emissions are less than 5 ppm, the system becomes much more sensitive to several independent system parameters. These include overall catalytic potential, effective ammonia injection/mixing in the flue-gas stream, flue-gas characteristics for inlet NOx, velocity, and temperature distributions.
