RCL® Catalytic Combustor

PCI is developing gas turbine engine catalytic combustors that enable low single digit ppm NOx emissions along with high combustion stability and a wide operating range. These devices offer to achieve the low emissions levels of aftertreatment technologies such as Selective Catalytic Reduction (SCR) or SCONOx without the associated cost, system complexity and reduction in gas turbine efficiency.

The PCI Rich Catalytic Lean burn (RCL®) Catalytic Combustor offers many desirable features without efficiency penalty across a wide turndown range such as:

  • Demonstrated ultra-low emissions (NOx<3, CO<10 ppm) at 15-17 atm.
  • No preburner required for operation
  • Compact - Capable of fitting to existing engine envelopes
  • High firing temperature robust operation
  • Long catalyst life
  • Fuel flexibility: The PCI RCL® Catalytic Combustor has been operated with multiple fuels including natural gas, low BTU gas, gasoline, and diesel
  • Reduced combustion acoustics enabling improved component life

Offering a Best Available Control Technology performance with significant operating and cost benefits, PCI's RCL® Catalytic Combustor is attracting interest  from power generation and industrial gas turbine manufacturers as well as from government agencies.  PCI is working with multiple gas turbine engine manufacturers, such as Siemens Westinghouse Power Corporation, and Solar Turbines to bring this technology to the power generation marketplace. Multiple Department of Energy, US Navy, and other government development contracts also support the development of PCI's catalytic combustion technology for gas turbine engines.
