Abstract
The U.S. Bureau of Mines evaluated the performance of a catalyzed diesel particulate filter (CDPF) and a CDPF combined with a diesel oxidation catalyst (DOC) at two metal mines. This paper describes the results from the two field evaluations. The CDPF/DOC was installed on an Elphinstone load-haul-dump (LHD) powered by a Caterpillar 3306 prechambered, turbocharged engine. The CDPF was installed on a Tamrock diesel-hydraulic roof-bolting jumbo, powered by a Deutz F6L912W engine. The underground evaluation at this mine was more difficult because of frequent movement by the roof-bolting jumbo, variation in the daily workload, tremendous fluctuation in ventilation air flow rate and the use of a high sulfur diesel fuel, which promotes the formation of sulfate particles, decreases filtration efficiency, and hastens the deterioration of the catalyst.
