摘要： A method and an integrated steel plant wherein, instead of using coke oven gases, converter gases and blast furnace top gases available as fuel for power generation or other heating purposes, these gases are more efficiently utilized as chemical agents for direct reduction of iron ores producing DRI. DRI is charged to blast furnaces increasing production of crude steel without increasing the capacities of the coke oven plant and blast furnaces and without changes in the quality of the crude steel, or, if production rate is maintained, the fossil fuels specific consumption is significantly reduced. Utilisation of primary fossil energy according to the invention also reduces the specific CO2 emissions per ton of crude steel. The specific CO2 emission in conventional integrated mills is about 1.6 tons of CO2 per ton of crude steel.

摘要： The invention relates to a method and system for destroying liquid toxic materials for example polychlorinated biphenyls, and producing a reducing gas. In a preferred embodiment, harmful intermediates are not generated when the toxic materials are destroyed due to the reducing atmosphere produced by partial combustion with a molecular-oxygen-containing gas and steam. Liquid materials containing high concentrations of PCB's are mixed with non-toxic hydrocarbons for sustaining an autothermic reaction. The efficiency of the PCB's destruction process exceeds the required environmental regulations and produces a useful reducing gas which can be utilized as a synthesis gas in chemical processes or as a fuel for heat and/or power production.

摘要： Method and apparatus for the production of prereduced iron ore, Direct Reduced Iron (DRI) (62), or the like, in an ironmaking plant wherein the reducing gas utilized in the chemical reduction of iron oxides is generated from natural gas within the reduction reactor system (5) by reforming the hydrocarbons with such oxidants as water and oxygen inside the reduction reactor (10) which is under steady state conditions contains metallic iron which acts as a reformation catalyst. The amount of carbon in the DRI (62) can be reliably controlled by modifying the relative amounts of water, carbon dioxide and oxygen in the composition of the reducing gas fed to the reduction reactor (10).

摘要： A valve for feeding abrasive particulate material to, and removal of particulate material from a pressurized vessel, adapted to operate at temperatures above 500 DEG C, comprises a valve structure wherein a single shutoff member of generally spherical shape performs both functions of shutoff the particulate material and the gas-tight sealing by means of a resilient inflatable circular seal element which engages the convex side of said shutoff member. Said seal element is inflated and cooled by a pressure regulated and continuously flowing stream of liquid water. The seal element is protected from being damaged at high temperatures by contacting it with the cooled shutoff member when the valve is closed and with a cooled circular extension of the shutoff member when the valve is open.
