This paper describes an experimental program that evaluates a number of methods which reduce the SO2 and particulate emissions from a CWS-fueled diesel engine currently being developed for the GE-locomotive. Calcium and CuO sorbents were tested for the reduction of SO2 while cyclones, metal fabric filters, and granular beds were tested for particulate removal. Significant reductions were measured when injecting calcium sorbent (either dry or wet) in the exhaust manifold. At a Ca/S atom ratio of 2, 40 percent of the SO2 is removed. SO2 removal using calcium hydroxide premixed with the CWM fuel is reduced by only 25 percent at a similar Ca/S ratio. Results evaluating CuO indicate that SO2 reduction is greater than 80 percent. The cyclone appears to effectively remove particulates expected from burning CWS in the diesel engine A pulse-jet cleaned particulate filter, constructed of sintered inconel fibers, can be used in combination with sorbent injection for SO2 control. For simultaneous removal of SO2, and particulates, a granular bed of copper oxide appears to be a viable alternative.
