    摘要: A valve strainer basket of an interceptor-type or control-type steam valve is removed from its nested orientation within a counter bore and valve rim of the valve casing. A strong back beam straddles the casing rim over the strainer basket. It is coupled to the strainer basket, such as by engagement of threaded rods into threaded apertures formed in the strainer basket rim. Biasing cylinders, such pressurized fluid cylinders or screw jacks, are interposed between the casing rim and opposite ends of the strong back beam. When the biasing cylinders are actuated, the strong back beam rises, lifting and separating the strainer rim from its nested engagement with the counter bore of the valve casing.

    摘要: A continuous steam generator including a combustion chamber with a plurality of burners for fossil fuel is provided. A vertical gas duct is connected downstream of the combustion chamber on the hot gas side, in an upper region via a horizontal gas duct. The outside wall of the combustion chamber is formed from evaporation pipes which are welded together in a gas-tight manner and mounted upstream of a water separator system on the flow medium side and from superheater pipes which are welded together in a gas-tight manner and mounted downstream of the water separator system. The water separator system includes a plurality of water separation elements, each element includes an inlet tube which is connected to the respective upstream evaporation for tubes, which extend into a water evacuation tube. A distributer element is arranged on the evaporator side between the respective water separator element and the inlet collector.

    摘要: In a method and device for protecting against erosion and/or corrosion steam pipes of the high-pressure stage of a power and/or steam generation plant saturated steam turbine, at portions of its low-pressure stage and at heaters of the heat exchanger installation of the power and/or steam generation plant, the major part of the water contained in the offtakes and the wet steam outlets of the high-pressure stage is separated out by centrifugal means. A first fraction of the steam partly dried by this means is superheated and/or final dried and then fed into the portions of the low-pressure stage of the turbine and a complementary fraction of the partly dried steam is fed to the heaters. The first fraction and the complementary fraction of the steam are dried together by centrifugal means after which the complementary fraction is final dried by centrifugal means.

    摘要: A method for monitoring air inleakage and oxygen content in a steam system, including the steps of: monitoring air flowing in the exhaust of a condenser; determining the total gas flow rate and oxygen content thereof; injecting a pulse of oxygen into the exhaust and measuring the transit time to the monitoring location; determining actual air inleakage rates, independent of or along with the oxygen content thereof; comparing the actual air inleakage and oxygen rates with predetermined rates; and, if the actual rates are increasing relative to the predetermined rates, isolating and eliminating the air inleakage and introducing more oxygen scavenger or, if the actual rates are decreasing relative to the predetermined rates, introducing less oxygen scavenger. The related device includes a conventional, high temperature, oxygen-solid, electrolyte cell sensor for monitoring the total gas flow rate and oxygen content in the exhaust, and an oxygen pulse injector located upstream of the oxygen sensor for introducing a pulse of oxygen into the exhaust. The transit time of the oxygen from injection to the monitoring location is measured by a timing device and recorder. The air inleakage rates, independent of or along with the oxygen content thereof, are then measured. The feedback from these rates is then used to control the amount of air inleakage and oxygen content in the steam system.

    摘要: A process for removing hydrogen sulfide from geothermal steam comprising adding free oxygen to the steam and contacting the steam with an oxidation catalyst at a pressure of at least 30 psig and a temperature not greater than the saturation temperature of the steam. The catalyst may comprise activated carbon, a refractory inorganic oxide or a metal phthalocyanine and is wetted with an aqueous solution of thiosulfates, sulfates or polysulfides. The hydrogen sulfide is converted and steam of reduced hydrogen sulfide content is obtained.
