Converter Off-Gas Systems

GEMKOM uses its technological manufacturing capabilities and experience, to produce and install off gas systems of integrated facility all over the world. Their high internal pressures, high gas temperatures, corrosive gases, complex piping geometries, requirement of special processes make off gas systems so difficult that only a few companies can produce.

Off-gas systems differ from ordinary water cooled ducts in the way that they produce steam with high pressures up to 60 bars and high temperatures up to 200°C. Steam generation requires accurate flow control and well balanced piping geometry. Special precautions like cladding, special material selection etc. have to be taken to prevent corrosive effects of off-gases.



The waste heat from any kind of off-gas is utilized by the steam, generated in the stacks. GEMKOM produces main parts of especially steel producing facilities like BOF, AOD, such as
