Bearing and steel manufacturer unveils many new products

Wind Power News >> 
The latest wind power news headlines, syndicated by rss from a variety of wind energy and industry news sources.

By making investments during the recession to expand its wind power offering and capacity domestically and internationally, The Timken Company, in Booth 2803, has introduced what it says is a record number of new product developments for the industry.

Recent products for the wind industry from Timken include new bearings and steel, lubricators, and condition monitoring equipment.

For example, the manufacturer of proprietary alloy steel and power transmission components and systems, has expanded facilities in Asheboro, N.C.; Tyger River, S.C.; and a new plant in Xiangtan, China, all to produce clean-steel from facilities in Canton, Ohio and wind bearing production in Wuxi, China; Chennai, India; and Ploesti, Romania. Working with the leading wind-turbine manufacturers at varying stages of development, the company has established a supply chain around the world.

Among technology innovations Timken is showcasing at the 2010 Wind Energy Conference and Exhibition in Dallas May 22-26, Booth 2803, are:

  • New Timken Wear-Resistant cylindrical and spherical bearings. This bearing technology extends operating life up to three times longer than standard cylindrical or spherical bearings, says Timken. With up to 15% less torque, the wear-resistant bearings resist  damages such as smearing, scuffing, false brinelling and micropitting (technical paper available from Timken). 
  • The new UltraWind Tapered Roller Bearing from Timken has the highest life ratings in the industry, as certified by Germanischer Lloyd. This main-shaft, ultra large-bore bearing has a simplified drivetrain design that saves capital-equipment costs.
  • Timken’s new Wind Energy Lubrication System enhances optimal wind power production by precisely and evenly directing fresh grease to bearing inlets while actively purging old lubricant with a, centralized-lubrication delivery device that works with either series-progressive or injector-based lubricant delivery methods.
  • Three new Wind Seals include the Eco Turn Labyrinth, a non-contacting design that prevents against grease migration and contaminants,

Next wave of wind-power opportunities? The after-market

Wind Power News >> 
The latest wind power news headlines, syndicated by rss from a variety of wind energy and industry news sources.

Mullins expects construction to start on about 6,000 MW of new wind capacity in the U.S. this year, which will carry a total investment value of about $10 billion.

Thousands of wind turbines have been built in the U.S. over the last few years, which means the after-market for equipment maintenance, replacement, and repair is about 12 to 18 months from taking off, says Shaun Mullins, Industrial Info Resources’ VP in Booth 9954.

“More wind capacity has been built in the U.S. over the last three years than in the previous 20 years combined,” he adds. “Starting in 2011 and accelerating in 2012 through 2014, the warranties on those turbines will start expiring. To reduce costs, windfarm operators must switch from reactive to predictive maintenance at a time when many OEMs will be playing catch-up, allowing for new equipment and service market entries.” One reason attendance has grown dramatically at the annual Windpower conference and exhibit is that hundreds of firms are entering the wind power after-market. “It will be a multi-billion-dollar business,” says Mullins.
Last year, nearly 10,000 MW of new wind capacity came online in the U.S., bringing the country’s total wind-power-generating capacity to about 35,000 MW, he says. However, new construction starts for wind since the beginning of last year have been cut in half. Many projects have been delayed or cancelled, and those that have moved forward have been scaled back and divided into phases.

“We still have a lack of financing, demand for electricity is still low, and natural gas prices remain low, which affects your sales pitch to investors and makes it more difficult to secure a PPA (power purchase agreement),” says Mullins. “Despite that, the lifeline provided by the American Recovery and Reinvestment Act has

Fire suppression for wind turbines made automatic

Wind Power News >> 
The latest wind power news headlines, syndicated by rss from a variety of wind energy and industry news sources.

FIRETRACE automatic fire suppression equipment provides fast and reliable protection for wind turbines.

The FIRETRACE automatic fire suppression system from Firetrace International is on display in Booth 11948. The device was developed for the fast and reliable protection of critical components in onshore and offshore wind turbines. The system operates without need for external power so it can activate automatically around-the-clock without requiring manual activation or monitoring. What's more, it needs almost no maintenance.

FIRETRACE is a cylinder filled with an extinguishing agent attached to proprietary Firetrace Detection Tubing by a custom-engineered valve. This leak-resistant polymer tubing is a linear pneumatic heat and flame detector immune to vibration and shocks. The tube was developed to deliver a required temperature-sensitive detection and delivery characteristics in wind-turbine equipment. When the tubing is exposed to heat and radiant energy from a fire, it bursts and instantly directs the suppression agent at the source of the fire, precisely where it starts and before it can take hold and do extensive damage to the turbine.

Instead of trying to protect the entire turbine, individual FIRETRACE systems protect critical areas most prone to fire, such as electrical enclosures, near generators, and adjacent cabinets housing controls or electrical transmission equipment. The system can also protect braking systems, generator enclosures, SCADA [Supervisory Control and Data Acquisition] systems, and hydraulic systems with potential to rupture near points of potential ignition.

FIRETRACE is said to overcome major drawbacks of traditional flooding suppression systems. Vibration can loosen connections on traditional systems, rendering them useless, while dirt, dust and temperature extremes are known to cause false alarms and false suppression discharges. This can result in the unwarranted disabling of the detection and suppression system, leaving the expensive turbine vulnerable to damage or destruction by
