In anticipation of the new
European standard EN 779.2012 for air filters, which classifies air filters
based on their lowest filtration efficiency, this article discusses the effect
that high humidity has on pressure loss during exposure to different dusts. For
example, individual test data show that variations of relative humidity cause
significant changes in pressure loss if NaCl is present in the loading aerosol.

This case study reviews the
process of replacing a main steam valve for an F-class heat recovery steam
generator (HRSG), including step-by-step photos. Given the extensive and
expensive effort involved, the author suggests that HRSG valve selections
consider quality and not just cost.

Gas turbine technology has evolved
with new alloys and smaller tolerances, increasing turbine efficiency but also
raising the importance of maintaining blade integrity. Salt particles in coastal
areas, humidity, and other conditions may pose specific challenges for selecting
air inlet filtration systems. This article discusses life cycle costs and other
aspects of Efficient Particulate Air (EPA) filters.

Filter efficiencies measure how
much of a specific particle is removed by a filter during a specified test.
However, other filter characteristics can affect plant performance and
compressor health. For example, filters are typically tested when dry. However,
media may not hold up as well under certain conditions and burst strength when
wet is not reflected in the efficiency rating.

After 200 hours of validation
testing, GE has increased the efficiency rating for their HA series turbines by
about a half point. For example, the 7HA.02 which had a simple cycle net output
of 330 MW and 61.2% combined cycle efficiency last year is now rated at 337 MW
simple cycle and 61.9% combined cycle efficiency in a 2x1 multi-shaft
configuration.

Mitsubishi has traditionally
targeted large gas turbines, whereas Hitachi focused on the small and
medium-size market with its H-25 and H-100 models, often referred to as the
H-series. The merger of the two companies’ thermal power businesses in early
2014 created Mitsubishi Hitachi Power Systems with products spanning from
approximately 30 MW to 330 MW in simple cycle. Recent mid-size capacity
additions include the H-100(110), H-50, and an uprate of the H-25 gas turbines
to 42 MW.

Northern Static Filters, based
in Abu Dhabi, UAE, is the Middle East’s largest manufacturer of gas turbine air
filter intake systems. The company was acquired by Donaldson in August 2014 to
serve markets in Europe, the Middle East and Africa. The company’s products
include the Norrvee and Norrcel series of air intake filters.

There is a switch from
coal-fired generation to gas turbine generators underway in many countries of
the world. In addition, a number of gas-turbine peaking plants are being
retrofitted with combined cycle systems. In major areas of the world more than
30 percent of turbine capacity is open (single cycle), which offers substantial
opportunities for combined cycle upgrades. The capacity additions in 2015 will
be equal to 4.3 percent of the installed base. However, the addition of steam
generators along with investment to switch from infrequent to frequent use will
raise total investment by 6 percent. Asia will be the leading region with a 7
percent increase. Gas Turbine Open Cycle Systems by Region…

The cyclic operation of peaking
plants introduces challenges that can result in damage to steam cycle
components. This article provides an overview of the components that may be
affected by low-load operation and highlights some potential solutions and the
trade-offs involved. For example, at low-load conditions it is often difficult
to keep heat exchange surfaces below design temperatures or operationally
limited temperature. Low-load operation also introduces enhanced risk of fatigue
damage and accelerated life consumption for Grade 91 piping materials.

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.
