Thanks to their flexibility, MTU brush seals lend themselves to use in a wide variety of industrial applications, providing excellent sealing solutions. Brush seals made by MTU have already chalked up well over 10.5 million operating hours in stationary turbomachinery.
Brush seals can be installed at various positions as dynamic seals (e.g. shaft seal, bearing chamber or rotor wheel seal) or as static seals (e.g. combustor seal).
MTU brush seals greatly reduce leakage losses which is the major benefit afforded by these innovative seals: They reduce leakage at the various sealing positions by up to 80 percent thus enhancing the efficiency of steam turbines by up to two percent. No mean feat considering that – according to studies conducted by GE Power Systems – about one third of the performance losses of steam turbines is attributable to leakage.
But it’s not just in conventional steam turbines that MTU brush seals have found a home. Today, this sealing concept can also be found in advanced ORC turbines.
Industrial gas turbines
For industrial gas turbines of all power categories, MTU provides tailor-made sealing solutions to reduce operating costs and improve efficiency as well as system reliability – for the benefit of customers and the environment alike.
