JBR Internals

A jet bubbling reactor is one of several methods used by coal-fired power plants to reduce SO2 emissions. The environment inside the reactor is highly corrosive, and FRP has proven over time to be, un-questionably, the material of choice for JBR internals. 

RPS Composites has partnered with design experts at some of America’s largest utility companies to manufacture FRP equipment that helps extend the life of their FGD assets. RPS is the industry leader in the design, and manufacture of FRP decks, down comers and gas riser tubes, FRP beams and columns, and FRP deck wash pipe and pipe supports. 

RPS vacuum infused FRP alignment grids are un-matched in cost and quality and have become the product of choice at many large utilities.

The figure below illustrates a typical JBR. For a look at another FGD process that uses FRP extensively, see our FGD Slurry Spray Piping.

RPS not only fabricates JBR internals but our Field Services division has more experience in the installation and maintenance of JBR internals than anyone in North America. So whether it’s your next shut down or a complete overhaul of your system, look to RPS as your turnkey resource for JBR internals.

Support Beams and Columns

FRP beams and columns are the primary infrastructure that support secondary structures like decks and grids.

Beams and columns can be vacuum infused or contact molded (hand layup).

Alignment Grids

Alignment grids are used to keep sparger tubes in place. They are manufactured to your specifications, and seamlessly fitted together inside the JBR with the same material as the grid itself. These are vacuum infused, and yield a highly consistent product.

RPS Composites’ piping and equipment have a proven track record in over 200 FGD plant installations dating back to 1970.

Today however, few coal-fired power plants are coming online, and existing plants are focused on extending service life of their assets. Whether you’re focused on service, retrofits, or replacement, choose a company that has been supporting the FGD industry from the beginning. Choose RPS.
