The RESONABTOR requires less room, is lighter, easier to maintain, more economical, has less thermal growth, has higher attenuation performance over the entire frequency spectrum, and has a tremendous reduction in pressure drop compared to historical silencer baffles.  With RESONABTOR we have revolutionized the silencer baffle design.  The RESONABTOR is a very complex and highly effective labyrinth system.  The 3-D sound dissipating system utilizes the physical feastures of reflection, diffraction and refraction.

Additionally, because of the flow straightening effect of the RESONABTOR, the pressure drop is reduced tremendously (up to 50%) when compared to historical silencer baffles.  Less pressure drop means more power and better Gas Turbine efficiency.

Every 8000 to 16000 hours a shut-down is required to exchange lamella seals.  The necessary frequent exchange of lamella seals produces huge maintenance cost due to material cost, changeout cost, and mainly due to shut-down time to perform the repair.  This is definitely no solution for modern power plant equipment.  NEVEXseal solves all these problems and stays forever gas tight with 100% sealing efficiency.  NEVEXseal is the ultimate next generation of diverter seals.  This patented system consist of solid vibration free adjustable seal ledges.  Once installed and adjusted, they never need to be exchanged.  

GRAVIMOV diverter technology is a pivot diverter that eliminates the internal toggle linkage, hot bearings, and cold shaft when in the bypass position.  A counter weight balanced power train allows for balanced & vibration free operation in any modulating position. The diverter flap design provides overflow openings in any modulating position by a given distance between the top end of the flap and the shaft.  The modulating efficiency is drastically increased by a flow at the diverter flap tip and by flow crossing over the diverter flap shaft.  The effect on the HRSG is tremendous because the flow distribution is balanced over the entire surface of the HRSG for an optimized and stress free pre-heating process.  The result is a shorter pre-heating period for the HRSG, and enormous fuel savings for those power stations frequently cycling.  

Low friction technology and optimized aerodynamics of the Diverter Flap reduces the required torque for actuation to less than 100,000 Nm across the entire range of controllability.  The power consumption of the actuator is only 4.0 KW, approximately 1/10th of the traditional units.  This allows the GRAVIMOV diverter to be offered with either a Hydraulic Power Unit or an Electric actuation.

The problem with traditional diffuser designs are that they have hundreds of gusset plates radiating heat to the outside while transferring body borne sound.  By utilizing our quietCOOL technology and introducing a spring support design, our diffuser has a significant reduction in heat radition and body borne sound.  Our goal is to eliminate the necessity for acoustic enclosures found with traditional diffusers.

We did it differently from the beginning by doing it systematically, frame by frame.
We reduced the number of studs to the cold casing by 50% to minimize heat transfer
and structure-born sound. The COMPACT cladding system is about 99.95% gas tight.
Each cladding sheet is secured by clamping the circumference allowing it to expand
freely in it's frame. The cladding sheet is back side stiffened by an angle profile which
also serves to hold the insulation in position as well as dampening to effectively
attenuate frequencies between 16 Hz and 500 Hz.

Separating a bigger part into pieces is not really sophisticated, but making it systemized is
sophisticated.  The sophisticated internal insulation system is the basis for the panel
design system.

Ease of Installation shortens Installation Time and Cost

The panels are based on a bolted design with flanges all around. The Panels are
completely insulated with cladding attached. The panels arrive on site in a transport rack,
whether for round or rectangular sections, they are ready to assemble. Only at the
corners will the panels be bolted with a special gasket in between the flanges to make it
gas tight. Build up the exhaust system, stack one section on to the other and bolt them
together. No welding work is required. This makes installation time shorter and of
course much more cost efficient.
