Piezocryst is nominated for the final round for the Innostar, an international media award for innovation
Piezocryst wins through to the Innostar finals (www.innostar.net) with its TOP-project (turbine optimization using pulsation sensors). Innostar is an international award for innovation where representatives of the international business press rate the proposed projects for their technology and for their individual story power. Piezocryst's high temperature sensors enable most precise pressure measurements at temperatures of 750°C over the entire lifetime of minimum 24.000 operating hours. They are used for the optimization of turbines for power generation, jet or ship propulsion, enabling significant improvements of fuel consumption and emission efficiency.
Modern turbines suffer from self excited combustion instabilities, a resonant phenomenon that leads to massive pressure pulsations within a turbine. These pressure pulses typically lead to 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.
