Abstract According to both theoretical analysis and practice, the decelerationof scale formation on the steel during direct fire heating was adopted by injectionof the water-in-oil emulsified fuel oil, replacing the conventional heavy oil, withan emulsifying equipment. To put into productive practice, the relative deceleratingrate after data from the Shanghai Pressure Vessel Plant and the Shanghai SteelWorks No. 3 is about 20 and 15% respectively. Mossbauer spectra showed that theFe_3O_4 content is much abundant in the scale, especially in its inside layer duringfiring the emulsified fuel oil, The reason, why the scale formation might berecelerated, seems to be a protective Fe_3O_4 film is formed and an excess of oxygenis reduced.
