To cool and clean the gas before use in an internal
combustion engine, a spray tower was designed,
fabricated and tested. It was cylindrical in shape with
an inner diameter of 0:35m and constructed using 1:5mm mild steel sheet. It was designed based on
inlet and outlet gas temperatures of 400◦Cand 45◦C,
respectively. Assuming that water at 30◦Cwas used
to cool the gas, the water Jow rate required was estimated
to be 0:63m3 h−1 [7,15]. A schematic diagram
of the spray tower is shown in Fig. 3.
