Abstract
A fully premixed duct burner is provided that receives exhaust gas from a power generating device, such as a gas turbine or reciprocating engine. The burner may include a burner surface adapted to combust the mixture on or above the surface in blue-flame mode. Substantially all exhaust gas passes through the burner with the exception of some small fraction of exhaust gas that passes through cooling holes or slots. The burner assembly can also include an array of burner modules that receive substantially all of the exhaust gas and fully premixes the exhaust gas with burner fuel prior to combusting the mixture on or above an array of burner surfaces.
Claims21
A duct burner assembly for use with a power generating device that generates exhaust gas, comprising:
- a premix section that is fluidly coupled to an exhaust duct of the heat generating device for receiving substantially all of the exhaust gas;
- one or more injectors that are operatively disposed within the premix section for injecting burner fuel and premixing the exhaust gas with the burner fuel;
- and
- a burner surface for receiving the premixed exhaust gas and fuel combination, and combusting the combination on or above the burner surface.
The duct burner assembly of claim 3 wherein the one or more conduits comprise three conduits.
A duct burner assembly for use with a power generating device that generates exhaust gas, comprising:
- an array of burner modules, the array of burner modules comprising:
- one or more premix sections that are fluidly coupled to an exhaust duct of the heat generating device for receiving substantially all of the exhaust gas;
- one or more injectors that are operatively disposed within the one or more premix sections for injecting burner fuel and fully mixing the exhaust gas with the burner fuel;
- and
- an array of burner surfaces for receiving the fully mixed exhaust gas and fuel combination, and combusting the fuel on or above the burner surface.
The duct burner assembly of 9 wherein each of the burner modules is capable of selectively being turned on and off.
