Coal retirements accelerate, gas and renewables gain market share

By Adam Picketts, Energy Ventures Analysis Inc

Natural-gas-fueled combined-cycle and renewables fleets will experience strong growth through 2018. Recent and impending EPA rulemakings require owners of coal-fired units to make significant capital investments on environmental controls. Faced with the decision to retrofit or retire, owners already have announced 45 GW of coal retirements from 2012 through 2018. Gas will be the primary source of replacement capacity as well as the top choice for new greenfield peakers and base-load resources. more

25% more GT capacity will be ordered for electric generation in the US this year than in 2012

Mark Axford, the Houston-based turbine consultant considered by many to be the leading independent expert on gas-turbine markets, predicted at the Western Turbine Users Inc’s (WTUI) 2013 Conference that US orders for GTs would increase by 25% this year compared to 2012. Worldwide, he expects only a 5% increase, with the Eurozone’s crippling recession a major factor in the downward pressure on orders (less than 800 MW last year). more

Pedigree and performance…The ‘Test of Champions’

By Salvatore A DellaVilla Jr, CEO, Strategic Power Systems Inc

On June 9, 1973, history was made in Elmont, NY, the town just outside of New York City famous for hosting the Belmont Stakes. That day, a crowd of 67,605 racing enthusiasts, plus another 10.9 million watching on TV, waited to see if a three-year-old thoroughbred named Secretariat, chestnut brown with a strong pedigree, would take the Triple Crown—a coronation that had not occurred since 1948.

Secretariat, would not disappoint in the “Test of Champions.” more


Inspect steam valves for stellite delamination

By Kim Bezzant, Structural Integrity Associates Inc

Stellite liberation from large valves installed in high-pressure (HP) and hot reheat (HRH) steam systems serving F-class combined cycles has emerged as an important industry concern. Tight shutoff of parallel-slide gate and non-return globe valves has been compromised in some cases, based on feedback from plant personnel; steam turbine components also have been damaged. more

Valves didn’t get the respect they deserved

The editors first learned of stellite delamination in a large valve designed for high-pressure (HP)/high-temperature steam service at the 2009 7F Users Group conference. But all the attention that incident received was a brief mention late in a long user presentation profiling the major inspection of a combined-cycle plant. More than 200 owner/operators were in attendance, yet no questions were asked about the issue—at least none the editors can recall—and it was quickly dismissed. Fig A shows stellite liberated from the seat of a 20-in. hot-reheat block valve installed at that presenter’s plant and collected in the strainer for the steam turbine’s combined stop and control valve. more
