Combustion - Products Summary
 Pressurized Combustion Technologies

Products Summary    Atmospheric Products    Hybrid Products    Pressurized Products

The Combustion Technologies products in this class are characterized by the
entire processes operating with combustion occurring at elevated pressure.
These systems use a gas turbine as the topping cycle, with steam
as the bottoming cycle power conversion technology. 

Pressurized combustion technologies are operated at elevated pressures (10 to 30 times atmospheric pressure).  Operating in a pressurized mode reduces plant size and increases plant efficiency by providing the opportunity to generate electricity using both steam and higher efficiency gas turbines.

Pressurized Fluidized-bed Combustion Systems (PFBC)

Operated at elevated pressures (10 to 30 times atmospheric pressure).  Operating in a pressurized mode reduces plant size and increases plant efficiency by providing the opportunity to generate electricity using both steam and higher efficiency gas turbines.  The gas turbine in this type of system gets all its heat from the PFBC and does not employ a topping combustor.

Advanced Circulating Pressurized Fluidized-bed Combustion Combined Cycle Systems (APFBC)

Systems with jetting-bed pressurized fluidized-bed (PFB) carbonizer/gasifier and circulating PFBC combustor.  The PFB carbonizer and PFBC both operate at elevated pressures (10 to 30 times atmospheric pressure) to provide syngas for operating a gas turbine topping combustor giving high cycle energy efficiency.  The remaining char from the PFB carbonizer is burned in the pressurized PFBC.  The combustion gas from the PFB also feeds thermal energy to the gas turbine topping combustor.  APFBC provides combined cycle plant efficiency using coal;  it uses high efficiency gas turbines in combination with steam turbines to add output.  This develops the greatest efficiency advantage from the coal's energy.
