摘要： A heat recovery steam generator (“HRSG”) includes a first casing having an interior enclosing at least one duct for gas to flow therein along a gas flow axis. Each duct is defined by duct defining members that are spaced apart from each other and extend into the interior of the first casing. A plurality of stiffening members are elongated along the gas flow axis. Each of the stiffening members are positioned between two of the duct defining members. The stiffening members and duct defining members have a substantially similar coefficient of thermal expansion.

摘要： The invention relates to a pulverized coal burner for a steam generator. The pulverized coal burner has a fuel duct, through which pulverized coal is conveyed with the aid of a carrier gas. The pulverized coal emerges together with the carrier gas at a fuel duct outlet. The pulverized coal burner furthermore has at least one core duct and at least one secondary duct. Air or oxygen flows through the core duct and the secondary duct, emerging at the core duct outlet and at the secondary duct outlet. The core duct outlet, the secondary duct outlet and the fuel duct outlet together form a burner outlet. The pulverized coal burner has at least one plasma ignition torch embodied integrally with the pulverized coal burner. The outlet of the at least one plasma ignition torch is arranged in the plane of the burner outlet or offset downstream in relation to the direction of flow of the pulverized coal. The plasma flame produced by the plasma ignition torch is thus located outside the fuel duct.

摘要： A combustion system having a furnace defining a combustion chamber includes a first burner disposed at an upper elevation of the combustion chamber and a second burner and a third burner disposed at a lower elevation of the combustion chamber. A first duct extends vertically to convey therein a fuel flow of gas and pulverized fuel. A second duct branches from the first duct to the first burner to convey a first portion of the fuel flow, which is fuel lean, to define a fuel lean flow, wherein a second portion of the fuel flow passes through the first duct as a fuel rich flow. A third duct includes one end disposed longitudinally within the first duct. An impeller is disposed within the first duct upstream of the branching of the second duct and downstream of the one end of the third duct disposed in the first duct. The impeller includes a plurality of blades to direct outwardly the pulverized fuel of the fuel rich flow to provide a fuel reduced content flow passing through the second duct to the second burner, and a fuel concentrated content flow passing through first duct to the first burner.

摘要： A method and apparatus for treatment of unburnts utilizing oxygen carrier particles, which may be CLOU particles, oxidized in an air reactor and transmitted to a post oxidation reactor as shown in FIG. 2. A flue gas stream containing unburnts is injected into post oxidation reactor wherein unburnts are oxidized by oxygen supplied by oxygen carriers. Reduced oxygen carriers are separated from post oxidation reactor and transmitted back to air reactor for re-oxidation. An embodiment may include a post oxidation chamber, which may be catalytic, receiving a portion of flue gas stream and oxygen from a flue gas stream of post oxidation reactor.
