Once again Piezocryst has been nominated for the Fast Forward Award, the Styrian Award for Technology
As in 2006 Piezocryst wins through to the Fast Forward Award finals. Besides the rating of the innovation, the technological and economical risks, in particular the quality of the company and the general conception of the project are assessed. Being a small to medium size enterprise Piezocryst, as a member of the AVL group, has to take part among the large-scale enterprises. That's why Piezocryst is proud that the quality of its work is sufficient to be elected among other more relevant players.
The project submitted are novel high temperature stable sensors that enable most precise pressure measurements at temperatures up to 750°C. The sensor is used for the optimization of turbines for power generation, jet or ship propulsion and contributes significantly the reduced fuel consumptions.
Modern turbines suffer from self excited combustion instabilities, a resonance phenomenon that leads to massive pressure pulsations within a turbine. These pressure pulses typically cause reduced efficiencies, but can also lead to the complete destruction of a turbine. To avoid those instabilities many OEMs use high safety margins to the optimal operating parameters. The underlying problem is bypassed, but the theoretical efficiency of a turbine with respect to fuel efficiency and emission efficiency can not be reached at all.
The new sensors are the enabling technology for the next level gas turbine control. The high temperature resistant pulsation sensors monitor the pressure directly at the combustion chamber and allow for running the turbine close to its optimal parameters. At the end of the day significant amounts of fuel and greenhouse gases can be saved, substantially contributing to the climate protection.
