Hot Topic Hour January 25 Silica Scale Issues
Join us on Wednesday, January 25 at 10:00 a.m. central time to hear and
participate in a discussion of silica scale issues and answers for the power
industry. Silica scale can cause problems in cooling towers and other equipment
based on:
§
High concentration in the raw water
§
Concentration mechanisms such as cooling water evaporation and RO
concentrate
We will be covering geothermal as well as fossil-fired power applications.
Bill Harfst
of Harfst Associates will co-host the session along with Bob McIlvaine of
McIlvaine. Power plant operators with scale problems will be encouraged to ask
questions. Suppliers of chemicals and equipment will be encouraged to provide
answers. We will also encourage the experts from the consulting companies to
join in as well.
There are three types of silica scale causing problems, Magnesium Silicate (the
most common), Aluminum Silicate and Iron Silicate.
The improvement in filtration and the need for chemical treatment go hand in
hand. The number of cooling tower cycles can be increased with better side
stream filtration, but the greater the number of cycles, the greater the
concentration of silica. Thus, preventing or dissolving the silica scale is
needed to enjoy the benefit of better filtration.
The session will be free of charge and open to everyone. You can register at:

“Hot Topic Hour” January 26 “Limestone Size Reduction and Regional Grinding”
The Utility MACT, Cross State Air Pollution (transport) Rule (CSAPR) and the
revisions to the National Ambient Air Quality Standards (NAAQS) will assure that
another 100,000 MW of scrubbers are installed over the next seven years, most of
them wet. These rules will also drive operators of existing scrubbers to achieve
the maximum performance and efficiency from their scrubbers to reduce their
emissions without the need for added equipment and to reduce operating cost.
The sizing of limestone figures into the equation for both emission reduction
efficiency and operating cost. Regional grinding has been utilized by some
facilities to reduce cost and with many more scrubbers coming online in the next
few years may be a solution for others.
Greg Andersen,
Manager of FGD Commercial Development at Mississippi
Lime Company will describe what is new in this field and to address the
economics of on-site versus regional grinding of limestone and the advantages or
disadvantages of each. He may also address the mechanics of grinding – equipment
types available and the capital and operating costs, maintenance issues and
reliability associated with each method of grinding, selection of stone size for
initial feedstock, wet versus dry grinding and any other issues that need to be
considered when making decisions relative to obtaining the proper quantity and
size of crushed limestone for a particular FGD system’s reliably and at the
lowest cost.

China to Spend $100 Billion Per Year on New Coal-fired Power Plants for the Next
Decade
China is planning to expand its coal-fired capacity from 646,000 MW in 2010
to 1,030,000,000 in 2020 according to the latest five year plan. This will
result in annual capital investment of $100 billion. It will include $10 billion
per year for air pollution control equipment. Coal-fired generation
investment will exceed that of gas, nuclear, solar or wind according to the
latest forecasts in the McIlvaine continually updated Fossil & Nuclear Power
Generation: World Analysis & Forecast.
India and a number of other Asian countries will be investing far more in
coal-fired power generation than in alternatives. Carbon sequestration is not
planned for the vast majority of the planned power plants. However, there
will be many ways that coal-fired power plants will become green.
·
Use the low pressure steam for co-located industries rather than waste it in a
cooling tower cycle,
·
Make byproducts such as hydrochloric acid, sulfur, ammonium sulfate and gypsum,
·
Replace old inefficient coal-fired power plants with 30 percent efficiency with
45 percent efficient ultrasupercritical power plants,
·
Co-locate desalination and municipal wastewater treatment plants with coal
generators.
The Spiritwood Plant of Great Rivers Energy is an example of how green coal can
become. The coal-fired power plant will use municipal wastewater for
cooling; the low pressure steam will be used for grain drying and for the
production of cellulosic ethanol. The residue from the cellulosic process can
then be used to replace some of the coal in the steam generation.
One of the problems in maximizing co-location of ethanol and municipal
wastewater treatment plants is the need to change the design to take advantage
of low pressure steam. In the case of cellulosic ethanol, the use of steam
at lower temperatures than are optimum will require larger process equipment. In
the case of municipal wastewater treatment plants, there needs to be a re-design
to take advantage of plentiful low cost heat to accelerate the biological
processes and dry the sewage sludge.

Small Wind Projects Have Their Place
Large scale wind projects grab many of the headlines but small scale wind
turbines are popular as well. A recent issue of McIlvaine’s Renewable
Energy Update described some recent installations.
*****
The Bergey Excel 10 is a 23 ft diameter horizontal-axis turbine designed to
provide the annual energy requirements for homes, farms, and small businesses.
More than 2,000 Excel turbines have been installed in 46 states and more than 50
countries. It has only three moving parts, requires no annual maintenance, and
was the first small wind turbine to carry a 10-year warranty. Excel owners
include hundreds of homeowners and farmers, schools, museums, state and federal
parks, all branches of the U.S. military, major corporations, and a number of
celebrities. One very happy customer is Gus Sansone of Oak Hills, CA, “I
installed my Bergey 10 kW in 2001. I haven’t paid an electric bill since the
turbine was installed and it’s paid for itself. It’s the best investment I ever
made.”
Bergey Windpower, the nation’s oldest manufacturer of small wind turbines,
announced that its best-selling BWC Excel 10 wind turbine is the first to
receive full certification to the new “AWEA Small Wind Turbine Performance and
Safety Standard”. “This new standard is the most significant milestone in the
history of the small wind industry because it provides, for the first time,
third-party verification of real world performance and a highly technical review
of a turbine’s strength and safety,” said Mike Bergey, President of Bergey
Windpower and the 2011 President of the Distributed Wind Energy Association.
“This is huge for consumers because it addresses the “hucksters and hype”
problem in the small wind marketplace. We are very proud to be the first to
achieve this game-changing certification.”
*****
Mass Megawatts Wind Power, Inc. announced that the company has recently started
the production of its wind power units in a manufacturing facility located on
Highway 8 in Morrison, CO. The new facility is located near our initial target
market in Colorado near Denver. The state is known for its leadership in the
field of renewable energy, including wind power.
The first wind power system built at the facility will be installed by a
dedicated team working during the harsh Rocky Mountain winter. The
installation site is near another small wind power unit built on site during
November. The wind power system leverages the patented, wind augmenter
technology that increases the wind velocity directed toward the wind turbine.
As many remote locations do not have access to traditional utility-power, the
wind power system offered by Mass Megawatts provides a cost-effective solution
for onsite power generation. The company is currently in negotiations with
agricultural, mining, and resort locations that are seeking an efficient,
low-cost, power source.
The company expects the wind system to generate power at a cost that is directly
competitive with fossil fuel methods. The system is also capable of operating in
lower, wind-speed locations, with reduced maintenance costs.

Xzeres Corp., designer, developer and producer of distributed generation, wind
power systems and power management and power efficiency devices for the
renewable and clean energy markets, announced that it has consummated a Dealer
Agreement with Weole Energy, the largest distributed wind energy dealer serving
the French marketplace.
“Besides France, we have also expanded our reach throughout other European
Community countries and anticipate additional prominent Distributed Wind Energy
Dealers to execute similar agreements with us in the near future, including
Germany, Italy and beyond. In addition we will continue our penetration in
Asia and expansion into other global markets such as South America and
Australia. All of these successes will also provide global channels
through which we will be able to grow and leverage our power management and
power energy efficiency devices as well,” said Frank Greco, CEO and President.

Siemens Industry Inc.'s Drive Technologies Division has launched a pilot program
partnership with Boston-based Eastern Wind Power to test several new solutions
for decentralized power generation in the small-mid range.
Siemens will provide drive train solutions for small-scale or micro power
generation projects between 30 kW and 900 kW. "This is an extremely fast
moving business segment, and our Drive Technologies Division is well-positioned
to provide complete drive train solutions for OEMs targeting decentralized power
generation," says Razvan Panaitescu, business development manager of the
distributed power generation and microgrids sector for Siemens Drive
Technologies Division.
Siemens partnered with Eastern Wind Power for a proposed six-month pilot program
in which the two parties integrated a Siemens 55 kW permanent magnet generator
and Energy Conversion System within the first prototype of Eastern Wind Power's
Vertical Axis Wind Turbine (VAWT).
The project is being conducted at Martha's Vineyard Airport in Edgartown, MA
where the airport manager and staff have enthusiastically lent their support.
Eastern Wind Power believes its Sky Farm™ concept of mounting between 10-20 50
kW VAWT's on the roofs of commercial or residential high-rise buildings is the
most efficient way to produce on-site distributed green energy in urban areas
which are land-poor but building-rich.
