    摘要： A plant for producing char and fuel gas includes a fluidized bed reactor having a first inlet in a lower region of the fluidized bed reactor configured to supply a primary fluidizing gas, a second inlet disposed above the first inlet and configured to supply a secondary gas, and a third inlet configured to supply dried and crushed coal. A further reactor is configured to perform a further process, the further reactor being directly connected to the fluidized bed reactor via a first conduit. A pneumatic injection and/or transportation system is disposed between the fluidized bed reactor and the further reactor. The first inlet is connected to a first supply of a first gas having an oxygen content which is smaller than a second supply of an oxygen enriched second gas connected to the second inlet.

    摘要： A process for producing pig iron or liquid primary steel products is provided. Charge materials containing iron ore and, if appropriate, additions are reduced in at least one reduction unit by means of a reducing gas, and at least parts thereof are smelted in a smelting unit, with coal being added and with formation of the reducing gas. Reducing gas from the smelting unit and/or top gas from the reduction unit are/is subjected to cleaning. The process water obtained during the wet cleaning is degassed and in the process volatile organic compounds are removed from the process water.

    摘要： This invention is intended to lower a temperature of a high-temperature exhaust gas to a desired temperature, while effectively suppressing adhesion of melting components and dusts in the high-temperature exhaust gas onto an inner wall of a cooling tower. For this purpose, a method of the present invention comprises an introduction step of introducing a high-temperature exhaust gas into a cooling tower through a gas duct, and a cooling step of sparging cooling water to the high-temperature exhaust gas in the cooling tower to cool the high-temperature exhaust gas. During the introduction step, the high-temperature exhaust gas is introduced into the cooling tower through the gas duct comprising two gas duct lines, in such a manner that respective portions of the high-temperature exhaust gas from the two gas duct lines become equal to each other in flow velocity and flow volume. Further, respective axes of the two gas duct lines are arranged so as to extend in directions opposed to each other and approximately orthogonal to an axis of the cooling tower, when viewed from a direction along the axis of the cooling tower.
