Abstract: A combustion rotation system that utilizes the placement, direction, and/or unbalanced fuel injection flow rates to the burners in a fuel-injection power boiler, such as pulverized coal, oil or gas fired boiler, to achieve Inboard/Outboard (I/O) rotation of the combustion mass or other types of mixing of the combustion mass. The over fired air (“OFA”) ports may also be placed, directed, and/or operated to contribute to the rotation of the combustion mass. The fuel-injection combustion rotation system may also be controlled while the boiler is operation, and controlled automatically, through a master control system. The fuel-injection combustion rotation system induces multiple vortex rotation of the combustion mass, which is more efficient and effective than attempting to rotate the entire combustion mass in a single vortex.

Abstract: A premixed air-fuel mixture supply device is joined to a combustor liner included in a combustor for a gas turbine or an aircraft engine. The premixed air-fuel mixture supply device has a pilot fuel injection unit having an inner wall, and a prevaporizing, premixing main fuel injection unit having an outer wall surrounding the inner wall. A combustion air passage is defined by the inner and the outer wall. An intermediate wall is disposed in the combustion air passage so as to divide an upstream part of the combustion air passage into a secondary combustion air passage surrounding the inner wall, and an outer combustion air passage surrounding the intermediate wall. Fuel inject holes are formed in the intermediate wall to inject fuel radially outward into the outer combustion air passage. A swirling device is disposed in the secondary combustion air passage to swirl combustion air flowing through the secondary combustion air passage. An atomization lip is formed in a tail part of the intermediate wall.

Abstract: A method of operating a pulverized coal-firing furnace so as to achieve no more than a predetermined variation in the instantaneous vertical velocities of the flow exiting a combustion chamber of the furnace is provided. The method includes, in one variation thereof, providing a series of lower compartments for introducing therethrough one of air, fuel, and air and fuel into the combustion chamber. At least one upper compartment is disposed above the topmost compartment of the series of lower compartments at a relative disposition to the topmost compartment in a spacing range between a contiguous disposition to a more spaced disposition which is no more than twice the average spacing between any given compartment and an adjacent compartment. Air is injected from the at least one upper compartment generally in opposition to the swirling fireball along a direction which is offset to the other side of the diagonal in a manner such that the injected air promotes the evolution of the swirling fireball into an upward flow in the top half of the furnace characterized by portions thereof flowing upward at differing vertical velocities with a maximum variation of no more than thirty percent between the instantaneous vertical velocities of the portions of the upward flow as measured across a horizontal plane in the top half of the furnace.

Abstract: A combustion chamber is provided that has a vertically oriented body with an inner surface defining an inner combustion area. A burner is disposed adjacent one end of the body so that the flame of the burner when lit will extend into the combustion area. A first annular insert is disposed in the combustion area and generally surrounds the flame of the burner. The annular insert defines a first secondary gas introduction zone for introducing secondary gases into the combustion area so that the secondary gases can be oxidized by the burner flame. The insert has an inner surface presenting at least one opening for allowing fluid communication between the introduction zone and the combustion area. A second annular insert is disposed in the combustion area below the first insert. The second insert defines a secondary gas extraction zone and a second secondary gas introduction zone located below the extraction zone. The gas extraction zone and second secondary gas introduction zone are separated by a divider plate. The gas extraction zone and second secondary gas introduction zone are generally separated by an annular inner wall which has openings therein to allow fluid communication between the combustion area and the extraction zone and second secondary gas introduction zone.

Abstract: A combustion system in which a coal/primary air mixture is discharged from burners located in the corners of the furnace towards an imaginary circle disposed in the center of the furnace. Air is discharged from air nozzles also located in the corners of the furnace in two flow streams--one directed towards the center of the furnace in a combustion-supporting relation to the fuel, and the other along the inner surfaces of the furnace boundary walls to maintain an oxidizing atmosphere and minimize corrosion and slagging.
