The present invention comprises a buffer memory for combined cycle (CC) power plants, which mitigates the effect of accelerated startup and shutdown of the gas turbine on the heat recovery steam generator. Hence, CC Power Plants are enabled to exploit the full potential of their gas turbines in the growing balancing power market without having to accept increased degradation of the waste heat boiler
Based on a very thin, high-strength design of the invention the ultrasonic sensor is placed between the teeth of the approximal region, thus reducing the distance significantly. As a result the images posses a very high spatial resolution.
The ultrasonic sensor consists of a metallic base plate with a reinforced frame, made of high-strength pure titanium or a TiAl6V4 alloy. The edges of the frame are rounded to make the insertion in the approximal region more comfortable. The total thickness of the design is limited to a maximum of 0.8 mm. The piezoelectric part is made on a PVDF-film equipped with spacers and shielded by an adjustable cover. The cover allows for a special contact by respecting the safety clearance to the teeth. By removing the cover hydrogel is pumped into the gap to provide acoustic coupling. In addition, it is used for lubrication of the cover movement.
