WebIron corrodes in water even in the absence of oxygen. An iron oxide surface acts like a car battery, with the surface divided into microscopic anodes (+) and cathodes (-). In condensate systems, iron acts as an anode so that it is oxidized (i.e., gives its electrons to the cathode). The cathode in pure water is a proton or hydrogen ion (H ... WebAt the discharge end, emissions are mainly iron and calcium oxides. A cyclone cleaner, a dry or wet ESP, a wet scrubber or a bag house absorbs the sinter strand wind box emissions. The cyclone collectors are installed ahead of the induced-draft fans to remove particles with diameters of 25 μm or greater.
