The popped borax-char column temperature produced from different combustion flue gas exit level or long duration of cooling of exhaust system (Figures 12 and 13). The temperatures at 50–200°C were tested in three column series for adsorption of SO2 as seen in Figure 14. Test results were determined as weight in TGA.

The popped borax-char column humidity produced from different combustion fuel and combustion temperature exit or fuel moisture content in the exhaust system. The steam amount in flue gas at exhaust chamber that varied at 5–20% was tested in three column series for adsorption of SO2 as seen in Figure 15. Test results were determined as weight in TGA.

Advanced materials and technologies should be used to prevent pollution of exhaust gas; the material used in this study is finally concluded as efficient and high cut with ecological environmental protection (Figure 16).

The representative poped borax composite samples at 1–3 mm sized pellet fractions of combustion Şırnak asphaltite, shale and coal waste raised SO2 sorption weight by the microwave radiation increased to 23, 21, and 12% at decreasing pressure., respectively, and all those valuse with char raised to 46, 24, and 14% at decreasing pressure. Microwave wet heating of porous coal did not change. The optimum sorption with char and ferrite using column was effective far more than waste coal and limestone as was discussed in microwave heating ability and heat conduction in the wet column designed in laboratory TGA.
