Coal-fueled diesel emissions control technology development: A status report
Since the last progress report, a 500 acfm system treating a slip stream from a single cylinder CWS fuel diesel engine was designed, constructed and tested. The system, as installed in the engine test laboratory, is shown in Figure 1. The system consists of a 6 in. diameter pipe with a flow control valve which diverts up to 500 acfm of exhaust gas from the single cylinder engine exhaust manifold. A gravity feeder injects sorbent into the exhaust gas stream which flows into the filter. In addition, anhydrous ammonia is injected into the gas stream from a pressurized cylinder to control NO[sub x] emission. The gas enters the filter housing from the top. Turning vanes direct the flow downwards toward the filter elements. The gas leaves the filter from the side. A detailed drawing of the filter, a filter element and compressed air system for cleaning the filters elements are shown in Figure 2. The filter media elements are closely spaced to increase the surface area-to-cloth ratio and to meet the space constraints. The filter media is composed of fiber metal with 3-5 micron fibers exhibiting good filtration characteristics. The fiber metal elements are relatively light and are constructed of Iconel or 316 SS, and can operate in the exhaust gas environment. High removal efficiency of particulate matter and S0[sub 2] was achieved using the barrier filter. The NO[sub x] removal efficiency was somewhat lower than was achieved in the bench scale tests, yet more than 85 % reduction of NO[sub x] level could be achieved.
