The Tuned Liquid Damper (TLD) relies upon fluid to provide a cost-effective method for damping.  The fluid is contained in an annular box, which is provided near the top of the stack.  This box contains an array of baffles which separate the damper into many compartments.  The baffles and compartments are designed to allow fluid to move internally and create the required damping force.   Several compartments are connected to form a “Chamber”.  The damper will have a minimum of two (2) chambers, but could have more depending upon the size.  These multiple chambers provide a factor of safety in the design as well as redundancy .  Depending upon the size of the damper, it may be supplied in one or more pieces.  If the damper is designed more than one piece, the assembly will be joined with bolted connections.

Special Designs:

The damper size is determined according to the stack parameters (i.e. requested additional damping, natural frequency, etc.);  However, in many cases the design of the damper allows the damper to be used as a top platform, a measurement platform, or as a connection device between a group of chimneys.  In those cases, the effective cost of the damper is extremely small.
