SKF develops online wind monitoring system
Swedish global engineering company, SKF, has devised an online monitoring system for the wind energy market which gives a continuous, real-time outlook on all sections of machinery.
The software package has been named the SKF WindCon System and has been developed with special adaptations to allow it to operate with offshore wind turbines.
The software operates by targeting three sectors. Firstly; a monitoring system is installed in the nacelle (the main body) of each wind turbine. This system collects data continuously and automatically carries out vibration monitoring of bearings, gearboxes, transmission, sensors and electronics. If a fault is detected, an alarm alerts supervisory systems.
Secondly; data collected from the monitoring systems is transmitted to a supervisory and analysis system placed in a control room that can be located anywhere convenient to the plant operator. Advanced machine diagnostics are performed and clear text messages regarding detected faults are given.
Thirdly; a specialist hotline where SKF can access the trend data via remote links. It can give input to identify actions to be taken in the event of doubt on the part of the local operating engineers.
SKF says the system was designed in accordance of the predicted 16.2 per cent wind turbine growth for 2006.
Alstom launches flowpac system
Alstom has announced the launch of Flowpac, its unique patented wet FGD (Flue Gas Desulphurization) system providing high collecting efficiency even from fuels with high sulphur content.
Design requirements for modern WFGD systems often require SO2 removal efficiencies as high as 98 per cent. Alstom has, therefore, developed a new absorber design that benefits from the use of a unique gas/liquid contacting zone and does not require the use of recycle pumps.
The flowpac features a high-efficiency turbulent bubble bed as the absorption zone, and the utilization of the oxidation air for both oxidation and absorption slurry turnaround. The flowpac has added advantages of no requirement for slurry circulation pumps, high SO2 removal efficiency and lower auxiliary energy consumption than conventional spray towers.
UK-based ash handling specialists Clyde Bergemann Materials Handling (CBM) has successfully commissioned a contract from Scottish Power Generation for a Waste Derived Fuel (WDF) storage and transportation system at its coal fired Longannet Power Station.
WDF is a dry, biologically benign and virtually odourless granule made from sewage sludge and although of a lower calorific value than coal, it represents a useful and valuable fuel. By mixing WDF with coal, then pulverizing it before co-firing it in two of four 600 MWe units, it will provide a fuel component for Longannet. In addition it will overcome an environmental problem by providing the means to burn WDF in an efficient, large scale generating plant.
CBM willsupply Longannet with a new transportation system based on its Rotofeed Injection Technology. The company originally developed Rotofeed for injecting granular coal into blast furnaces. Its dual advantages of keeping the material totally enclosed while allowing accurate feed rates makes it ideally suited to handling WDF.
RJM expands emission technology
RJM Corporation announced the launch of the RJM A3 SCR System, which is geared towards achieving up to 98 per cent NOx reduction in addition to CO and HC reductions on large stationary reciprocating engines at an affordable compliance cost.
Robert Monro, vice president of RJM said: “The RJM A3 SCR System is specifically designed for dual fuel engines that require a large turn down ratio of reagent fow. The system modulates the urea flow over a turndown rate of 40:1, making it ideal for large reciprocating engines over 3000 hp.”
The technology is designed on RJM’s atomizer and controls technology. The atomizer is custom built to the engine requirements and tested using a Laser Doppler beam for droplet size and spray quality. The control system is PLC based.
Ravi Krishnan, RJM’s director of planning and marketing said: “The A3 SCR System will make power production costs from large diesel and gas reciprocating engines more competitive in the market.”
GE taps telecoms
GE Power Systems is widening its portfolio of products for the energy rentals market by offering compact diesel gensets for telecommunications applications.
The first 85 units, with remote control and monitoring abilities, have been installed and tested in Ireland.
This expansion is being driven by third-generation technology that enables greater channel capacities for voice communications and faster wireless data communications.
