Pilot Scale Combustor Test (PSC) Test Facility

The main objectives:
  • Evaluate different fuels and operating conditions
  • Predict stoker performance and emissions
  • Improve product designs

The PSC simulates a solid fuel fired furnace with a spreader-fired grate. The system can reproduce temperatures, gas composition, and residence times found in conventional boilers. Studies are performed under controlled conditions simulating operating characteristics of commercial-scaled boilers. 

The system is capable of firing:
  • Solid fuels
  • Liquid fuels
  • Gaseous fuel blends
Observable effects that can be examined:
  • Volatile evolution
  • Char combustion
  • Pollutant formation
  • Staged combustion
  • Ash deposition and fusing characteristics
During the operation of the unit, the following data is collected:
  • Emissions (CO,O2, NOx, SO2)
  • Continuously monitored temperature profiles and combustion air flows
  • Intermittent fuel and ash sampling
  • Analysis include in proximate, ultimate, metals, carbon losses, etc by independent test houses.
Other Related Testing:
  • Corrosion testing
  • Speciation of flue gas/syngas by Gas Chromatograph
  • Combustion gas tar sampling
  • Sorbent injection for emissions reduction
  • Gasification/pyrolysis studies
  • Fuel delivery methods

Real-time and high-speed video is also available and allows the recording of test burns. The results from the PSC in conjunction with the DSC fuel spreader test facility are fully implemented using proprietary Computational Fluid Dynamics (CFD) computer code.  This integrated program allows DSC to fully implement a complete solution to combustion problems and develop modifications for the client.
