Description: Das Projekt "Rueckgewinnung von Konvertergas in der Stahlproduktion nach dem KMS-Verfahren" wird vom Umweltbundesamt gefördert und von Maximillianshuette durchgeführt. Objective: In converter steel plants operating in accordance with the KMS process (Kloeckner-Maximilianshütte-Stahl), the production of steel from hot metal and scrap results in waste gases with high CO contents, which have been flared through stacks to date. Three converter plants of the Maximilianshütte are to be equipped with a controlled gas suction and gas recovery system to permit the application of the usable converter gas for the production of process heat and steam by way of intermediate storage. It is to be expected that the annual energy saving at project level will be 6.500 TOE for the production of raw steel, as proposed in this project. General Information: The project is part of an extensive programme for the conservation of energy in the Sulzbach-Rosenberg works. The Maximilianshütte operates a KMS-steelworks there equipped with three converters, each having a capacity of 60 t. The converters are equipped with cleaning systems based on a wet cleaning process. These operate with the assistance of two Venturi stages. A controlled gas collection system is used for suction at the mouth of the converter to prevent combustion of the waste gases containing CO above the mouth. The most important components of this gas suction system, e.g. A controlled skirt which can be moved upwards and downwards, were installed during the construction of the steelworks. Within the scope of this project, the actual gas recovery and gas storage facility is to be developed, erected and tested. Gas recovery requires switch-over stations as well as diverse closed-loop control and control systems, which permit switch-over to gas recovery during the blowing process depending on the CO content of the converter gas (switch-over point at a CO content of about 40 per cent). Pneumatic drives are provided for all switch-over elements. The gas will probably be stored in a low pressure telescopic gasometer equipped with a special shell sealing. Gas storage serves to equalize the irregular gas production. In the first phase of the project, a measuring programme will be implemented following the installation of diverse measuring instruments. Its purpose is to determine the data on the temporal decrease in the amount of gas, the composition of the converter gas and the gas curves occurring behind the cleaning facility in the course of one heat. Such data are required to dimension and design the necessary facilities. These results will be used to determine the process course for the recovery of gas and to design and plan the facilities. Following the erection, the overall facility will be tested in the course of an 8 month demonstration period and final evaluation will be effected. Achievements: The 3 gas analysis systems were commissioned on march 3RD 1985. After this, measurements were carried out on the 3 converter plants during the month of July 1985. A description of the gas analysis system follows; the converter gas is taken via 2 gas sample probes which are ...
