Abstract: 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.

Abstract: A method for reducing mercury emission and/or re-emission in cleaned flue gas through control of sulfite concentration within a wet flue gas desulfurization (WFGD) system is disclosed. One method for reducing mercury emission and/or re-emission through control of sulfite concentration is to measure the sulfite concentration of an aqueous alkaline slurry used in a WFGD system and comparing the same to a predetermined sulfite concentration value. If the comparison reveals the measured sulfite concentration is above the predetermined values, the amount of oxidation air supplied to the system is increased. If the comparison reveals the measured sulfite concentration is below the predetermined values, the amount of oxidation air supplied to the system is decreased.

Abstract: The invention relates to a modular blade or vane for a gas turbine, which includes the modular components of a platform element with a planar or contoured surface defining a platform level and a through-opening therein, and an airfoil, extending through the platform element. The airfoil includes a load carrying structure extending along a longitudinal axis of the airfoil, having a root portion for fastening on a blade or vane carrier of the gas turbine, having a tip portion, and having at least one interior passage, extending from the root portion to the tip portion of the airfoil. An aerodynamically shaped shell extends in a distance over the carrying structure and defining the outer contour of the airfoil. A longitudinally extending gap, is disposed between the carrying structure and the shell. A number of through-holes in the carrying structure direct a cooling medium from the interior passage into the gap. The shell is integrally joined to said carrying structure by a first joint in a region below the platform level of the platform element. The shell is joined to the carrying structure by at least one additional joint, wherein said at least one additional joint is a form-fit joint, allowing relative movement in longitudinal direction between shell and carrying structure.
