Compliance Strategies for PM2.5 is Hot Topic Hour on Thursday May 12,
2011
Now that the Utility MACT has been proposed, power plant engineers know the
limit for particulate emissions. Now the question becomes "Can this plant meet
the limit at an economic cost and if so how?" For some plants, the solution may
be to simply improve the efficiency of existing processes and equipment. At some
of the larger plants, it may be necessary to add new control equipment such as a
baghouse. But at smaller plants there may not be an economic solution and shut
down may be the choice of the utility.
The following speakers will describe the options available to power plants of
all sizes to achieve the proposed MACT particulate limits. They will address the
available technologies, capital and operating costs,
the advantages or disadvantages of the options for specific plant configurations
and operating conditions and factors to consider when
selecting a particular control strategy.
Steven A. Jaasund,
P.E. Manager of the Geoenergy Division of A.H. Lundberg Associates, Inc, will
explore the pros and cons of retrofit wet ESPs in the utility environment.
Recently proposed MACT rules for utility boilers may require the addition of
particulate control equipment. Wet electrostatic precipitator technology
is a logical add-on alternative to help meet these rules. This is
particularly true if boiler emissions are already being treated with a wet FGD
system.
John D. McKenna,
Ph.D., principal and founder of ETS, Inc, will discuss compliance strategy
options and costs for PM2.5 control for utility coal-fired boilers.
Capital and operating cost will be compared for three alternatives:
electrostatic precipitators, pulse jet and reverse air baghouses. A
hypothetical example is developed in detail. The pros and cons of each
option will be discussed.
Terence R. Ake,
Product Manager for Turbosorp® Circulating Dry Scrubbers at Babcock
Power, Inc, will describe why a circulating dry scrubber is one of the best
options to reduce particulate matter (PM) from utility coal-fired and
waste-to-energy boilers. The EPA is proposing national emission standards for
solid, liquid and gas fired industrial and utility electric steam generating
units for hazardous air pollutants under the Clean Air Act. The new
standards target total particulate - both filterable (PM2.5) and
condensable particulate. A circulating dry scrubber is one of the best
options to reduce particulate matter (PM) from utility coal-fired and
waste-to-energy boilers because of its ability to remove both filterable and
condensable PM while also removing SO2, HCl and Hg that are also
limited in the standards. There is no provision for boiler startup,
shutdown or malfunction in the EPA standards. For utilities that install
continuous emission monitors for PM (as a surrogate to measuring non-mercury
hazardous metal emissions), the EPA will compare a 30-day rolling average with
the PM limit. To ensure that a boiler stays below the rolling average
limits for PM, SO2, HCl, and Hg species, the circulating dry scrubber
must be able to remove the species well below the limits with a high degree of
availability.

Wind Industry Continues to Innovate
With global wind power installations nearing 200 GW the wind industry is
continuing to innovate. New technologies and improvements on existing
technologies are reported each month in McIlvaine's Renewable Energy Update.
Vestas has revealed the details of its next generation dedicated offshore
turbine. To ensure the lowest possible cost of energy this new machine, the
V164-7.0 MW, boasts an entire 7.0 MW and a rotor diameter of 164 meters.
Lowering the cost of energy in relation to offshore wind is essential for the
industry. Some of the major stepping stones in achieving this are size and
subsequent increased energy capture, which means a need for much bigger turbines
that are specifically designed for the challenging offshore environment.
According to Anders Sře-Jensen, President of Vestas Offshore, the offshore wind
market is set to really take off over the coming years, but more so in some
parts of the world than in others: "We expect the major part of offshore wind
development to happen in the Northern part of Europe, where the conditions at
sea are particularly rough. We have specifically designed the V164-7.0 MW to
provide the highest energy capture and the highest reliability in this rough and
challenging environment.
Construction of the first V164-7.0 MW prototypes is expected in Q4 2012. Serial
production is set to begin in Q1 2015 provided a firm order backlog is in place
to justify the substantial investment needed
GE has introduced its 4.1-113 wind turbine, a four-megawatt (MW) class machine
that is optimized for offshore use and is designed to bring a new level of
reliability to the offshore wind industry. GE has signed a contract to supply a
4.1-113 wind turbine, along with associated services, to Göteborg Energi for
installation in the Gothenburg, Sweden harbor in the second half of 2011, GE
announced at the European Wind Energy Association's EWEA 2011. This project is
supported by the Swedish Energy Agency through its technology program,
demonstrating its interest in leading offshore technology.
With fewer moving parts, the direct-drive technology provides a simple, reliable
design with built-in redundancy and partial operation for major components, all
focused on keeping turbines operating reliably at sea. The direct-drive
technology eliminates costly gearbox parts, lowering operating expenses, and
also relies on an innovative modular approach to maximize in-situ repair and
reduce the need for large repair vessels. The 4.1-113 blade design is optimized
to maximize energy capture.
GE has also introduced taller towers for its onshore wind turbine product line.
The new towers enable higher annual energy production (AEP) and increase the
number of potential wind sites. The towers initially will be offered for GE's
2.5-MW series including the new 2.75-103 wind turbine. The taller towers are
available with hub heights in excess of 130 meters.
Initial key markets for the new, taller GE wind turbine towers will be Germany,
Scandinavia, Poland, Romania and Canada.
Nordex USA, Inc. will debut its new N117/2400 wind turbine for the US market at
WINDPOWER in Anaheim, California. The latest addition to the company's Gamma
Generation of turbines, the N117 is designed specifically for light wind sites,
creating new power generating potential for locations across the country
The acoustic power level is limited to a maximum of 105 decibels, allowing the
turbine to be used closer to residential areas and facilitating optimal turbine
layout at wind farms. Its hub height on a standard tower of 91 meters remains
below the FAA threshold of 500 feet.
Suzlon Group announced the launch of its new S9X suite of wind turbines at the
Wind Power 2011 conference in Chennai, India.
The S9X suite of turbines has been specifically designed keeping in mind the
needs of the market.
Every aspect of the turbine, the blades, the generator and sub-systems feature
improved designs to deliver a higher return on investment. The machines also
have better grid compatibility and are in accordance with the highest safety
standards.
The S9X suite is an evolution of Suzlon's technology platform, and is built
around a core doubly fed induction generator-based technology. A compact and
modular DFIG design allows ease of serviceability and meets the latest grid
requirements for smoother wind power plant connectivity. New blade designs with
rotor diameter of 95 meter and 97 meter offers a larger swept area add to this
with greater energy capture and power production from moderate to low wind
speeds. To ensure the highest standards in quality, Suzlon's blade testing
simulates total life cycle of blade (1 million cycles) in most extreme onsite
conditions.
The turbines boast of variable tower heights of 90 or 100 meters, leading to low
cost optimization and higher power generation. The S9X turbines also comply with
low voltage regulation (LVRT) requirement, this leads to better compliance with
grid regulation.
Additionally, improved sub-systems like the new pitch and yaw systems have
increased system reliability of the machines.
Serial production of the S95 turbine is scheduled to begin in Q2 FY11 - 12.

following the renewable energy field for the last five years.
Methane 72 Times More Potent than CO2 over 20 Years
This Alert has covered the new evidence that gas-fired power plants result in
more greenhouse gases than coal-fired power plants. This evidence revises some
data about the quantity of methane leaks and the indirect energy increasingly
required to extract natural gas, but the big difference is the timeframe.
Methane decays to CO2 in the atmosphere after a decade or so. CO2
lasts for many decades. Over 100 years the greenhouse gas potential of
methane is only 20 times that of CO2. Over 20 years it is a whopping
72 times greater. We have a huge inconsistency in the forecasts for
cataclysmic results if we continue to burn coal. On one hand we are told that we
are a few years away from disaster. On the other the calculations are based on
impact comparisons over 100 years. Over the short term gas-fired
generation is a much bigger contributor to global warming than coal-fired
generation.
Broad public backing for coal can be achieved by presenting coal as a 25 year
bridge to whatever energy form is best for 2045 and beyond. The following
results can be shown for a complete fleet of new coal-fired power plants to be
phased in at 30,000 MW/yr for the next 10 years.
·
Lowest emissions of all pollutants (calculated in equivalent tons of CO2).
·
Lowest electricity cost of all the options for improving the environment.
·
$600 billion stimulus to the economy.
·
Certainty over fuel costs.
·
Energy security benefits.
·
Reduce coal use by 30 percent and use that coal to make liquid fuels.
