Abstract: A system and method of igniting a coal air-fuel mixture, including a burner having a burner tube operable to carry a flowing mixture of fuel and air to a furnace for combustion therein and a first flow directing device disposed within the tube, operable to direct a first portion of the flowing fuel and air mixture to a location in the burner tube. The system also includes a laser igniter within the burner tube, the laser igniter including a laser tube having a first end with a laser light input and a second end with a light output, and a laser light source operably coupled to the laser light input. The laser light source, including a laser. The laser ignitor directing photons from the light output at the location in the burner tube to ignite at least a part of the first portion of the fuel.

Abstract: A combustion system comprising a burner for supplying a mixed flow of fuel and primary air or gas through at least one fuel nozzle to a combustion chamber, a duct in fluid communication with the at least one fuel nozzle for guiding the mixed flow to the at least one fuel nozzle, and a deflector device positioned within the duct upstream of the at least one fuel nozzle to deflect the incoming mixed flow. The deflector device comprises ejection means arranged to eject an auxiliary gas into the duct to deflect the incoming mixed flow in a direction from a center to outer areas of the duct to increase the concentration of the mixed flow in outer areas of the fuel nozzle and decrease the concentration of the mixed flow in the center section of the fuel nozzle.
