| 20090308331 | OXYGEN CONTROL SYSTEM FOR OXYGEN ENHANCED COMBUSTION OF SOLID FUELS - A combustion system and method for operating a combustion system, such as a furnace or boiler. The method includes providing a burner system having one or more burner elements configured to combust solid fuel and one or more oxygen providing devices configured to introduce oxygen into the near burner zone of one or more burner flames. A sensor is provided and arranged and disposed to measure a flame parameter in the near burner zone of the burner flame associated with one or more the burner elements. The flame parameter is measured with the sensor and an oxygen flow is determined in response to the measured flame parameter. Oxygen flow is introduced to one or more locations in the combustion system with the one or more oxygen providing devices. | 12-17-2009 |
| 20090311642 | Oxygen Control System For Oxygen Enhanced Combustion - A method of configuration of combustion process control. The method includes providing a combustion system having a plurality of burner elements, a plurality of gas injection points and a controller. The gas injection points are configured to provide a support gas. One or more tasks for operation of the combustion system are determined. A plurality of groupings of the gas injection points are determined for each of the one or more tasks. An individual ranking for each of the plurality of groupings is determined in response to the one or more tasks. A composite ranking of injection points in response to the individual rankings and the controller is configured to operate the plurality of gas injection points in response to the composite ranking. A combustion system and a method for operating a combustion system are also disclosed. | 12-17-2009 |
| 20100077942 | OXY/FUEL COMBUSTION SYSTEM WITH LITTLE OR NO EXCESS OXYGEN - The disclosure includes a combustion system including a primary reactor arranged and disposed to receive a solid fuel and a first oxygen stream and deliver a first substantially gaseous product and a substantially solid or molten product, a secondary reactor in fluid communication with the primary reactor, and a furnace in fluid communication with the secondary reactor. | 04-01-2010 |
| 20100077945 | CONVECTIVE SECTION COMBUSTION - An oxy/coal combustion system and method include a furnace arranged and disposed to receive and combust a first solid fuel to form a combustion fluid, a convective section having one or more inlet devices, the convective section arranged and disposed to receive and combust a second fuel in the presence of the oxygen, and one or more heat exchangers arranged and disposed to exchange heat with the combustion fluid. | 04-01-2010 |
| 20100077968 | OXY/FUEL COMBUSTION SYSTEM HAVING COMBINED CONVECTIVE SECTION AND RADIANT SECTION - A heat transfer system having a a radiant source, a first heat exchanger configured to permit a first fluid to flow therethrough, and a thermal shield configured to provide controlled radiative heat from the radiant source to the first exchanger. The radiant source is a flame. The thermal shield is a second heat exchanger configured to permit a second fluid to flow therethrough or a non-contact thermal shield fabricated from a material arranged to provide controlled radiative heat exposure from the radiant source to the first exchanger. Oxy/coal combustion systems are also disclosed. | 04-01-2010 |
| 20100081099 | TRANSIENT OPERATION OF OXY/FUEL COMBUSTION SYSTEM - According to an embodiment, a method of operating an oxy/fuel system and an oxy/fuel system circulate a support gas in the combustion system prior to activating at least one burner, produce the combustion fluid including CO | 04-01-2010 |
