摘要： PROBLEM TO BE SOLVED: To provide a cyclone separator of a steam drum, which is used for separating the vapor-liquid-mixed fluid generated by heating in the furnace of a boiler into saturated steam and saturated water and in which the separation efficiency of steam from water and that of steam from mist are enhanced in the cyclone part and the primary scrubber part respectively. SOLUTION: The cyclone separator is composed of the cyclone part and the primary scrubber part. The cyclone part has a double structure of an inner cylinder and an outer cylinder. The primary scrubber part is constituted by arranging a hollow part and a whirling vane and a cap member around the hollow part successively. The separation efficiency of steam from water and that of steam from mist are enhanced by subjecting the vapor-liquid-mixed fluid to gas-liquid separation by using centrifugal force in the inner cylinder of the cyclone part, withdrawing the saturated water from the lower part side of the outer cylinder into the steam drum by making the saturated water pass through a passage formed from the upper part side of the inner cylinder to the outer cylinder and withdrawing the steam after separating the mixed mist in the primary scrubber part.

摘要： PROBLEM TO BE SOLVED: To facilitate the work of a furnace wall surface panel or a burner panel and contrive the simplification of a structure as well as the improvement of property of maintenance by a method wherein the shape of a burner nozzle or a burner throat is formed so as to be asymmetrical with respect to a vertical surface and the opening surface of an end part is positioned in the same plane as the side surface of the furnace or in a plane parallel to the same. SOLUTION: The axial line 8 of injecting direction of pulverized fuel and transfer air into a furnace is coaxial with the axial line of injecting direction of auxiliary air for combustion into the furnace while the vertical surface, including these coaxial lines, is not orthogonal to the side surface 7 of the furnace and is slanted. The shape of a burner nozzle is asymmetrical with respect to the vertical surface including the axial line 8 of injecting direction. Such a shape is employed, whereby the opening surface 2 of the burner nozzle can be positioned in the same plane as the side surface 7 of the furnace and combustion can be effected without generating a phenomenon, in which flame is collided against a furnace or is ran along the furnace wall tube 6, even when the furnace wall tube is not arranged so as to be faced toward an air box with an angle between the side surface of the furnace as a traditional manner.

摘要： PURPOSE:To reduce loss caused by unburnt gas so as to enhance the efficiency of an exhaust recombustion boiler by mixing gas containing rich oxygen and extracted from exhaust gas from the boiler, into exhaust gas from a gas turbine so as to increase the concentration of oxygen in order to make the ignition of fuel satisfactory in the boiler and to sustain stable combustion. CONSTITUTION:Exhaust gas from a gas turbine 7 is fed into a boiler 1 by way of a pipe line, in place of air for burning fuel. In this case, a pressure swing type gas absorbing and separating device 31 is provided between an induction type ventilator 12 and a funnel 14 so as to remove nitrogen, carbon dioxide, steam and the like from exhaust gas from the gas turbine 7 in order to obtain gas containing rich high purity oxygen. Further, the gas containing rich oxygen is fed through a pipe line 32 into the pipe line 8 so as to increase the concentration of oxygen in the exhaust gas which is then fed into the boiler 1 for combustion of fuel. Meanwhile, a part of gas containing lean oxygen is charged, as inert gas, into a mill side pulverized coal system of a resting one of first and second mills 18.
