Vibro-Meter Helps Japanese Industrial Giant to Improve Efficiency and Environmental Performance
Vibro-Meter is pleased to announce a significant order from the mighty Japanese concern Mitsubishi Heavy Industries (MHI). The order covers the supply of dynamic pressure transducers and accelerometers (vibration sensors) with their interconnecting cables, over the next three years. The transducers are part of new technology solutions to help MHI Power Generation Division improve machine efficiency and environmental performance, particularly via a reduction in NOx emissions. A patent protects the design of the pressure sensor. Typically 16 pressure sensors and four accelerometers will be fitted to the majority of large industrial turbines supplied by MHI.
MHI is a giant organization providing a broad range of products and services including shipbuilding, steel structures, power systems, air conditioners, machinery for industrial and general use, aerospace systems, and more. Last year they delivered goods and services worth ¥2,454 billion (36 billion Swiss francs, 57.6 billion US dollars). The Power Generatioin Division can supply everything for power stations of all types, from components to complete facilities, and has been designing and manufacturing gas turbines since 1961. Today they offer a range of gas turbines from 6 to 300 MW.
Vibro-Meter dynamic pressure transducers are used in many industrial gas turbines to detect and control instabilities in fuel combustion. Combustion instability can rapidly cause extensive internal damage, necessitating shut-down and repair. As gas turbines are being continually improved to operate with greater efficiency and lower harmful emissions, the combustion process becomes more and more critical. A combination of pressure and vibration sensors can detect the onset of combustion instability, allowing the automatic control system to respond and avoid the problem. Vibro-Meter designs and builds dynamic pressure transducers that are uniquely adapted to th is demanding application, where the sensor must operate reliably in temperatures up to 700ºC with very high vibration levels. Using carefully chosen piezo-electric materials, and incorporating a vibration compensation element, Vibro-Meter dynamic pressure transducers are contributing to improved reliability and efficiency in gas turbines around the world, thus helping customers and the environment.
