| 摘要： | In recent years, researchers from the National Institute for Occupational Safety and Health (NIOSH), working under an interagency agreement with the United States Coast Guard, evaluated carbon monoxide (CO) emissions and exposures from gasoline-powered generators equipped with emission control devices. This evaluation was part of a series of studies conducted by NIOSH investigators to identify and recommend effective engineering controls to reduce the CO hazard and prevent CO poisonings on houseboats and other recreational marine vessels. In previous studies, NIOSH researchers have evaluated CO emissions from Westerbeke generators that have included the necessary technology to reduce and control CO emissions. Kohler Power Systems recently released to the public a new line of low CO emission generators with catalytic technology. During this study, NIOSH engineers conducted a follow up evaluation of a 15 kW low CO emission Kohler generator installed in a 16' x 59' houseboat equipped with a stack exhaust configuration. At the time of this evaluation, the 15 kW generator was the largest low CO generator manufactured by Kohler for the houseboat market. The new Kohler generator had been used for a full rental season and it recorded 1082 hours prior to the evaluation. Representatives from Kohler, the U.S. Coast Guard, and Forever Resorts attended the evaluation. Results from this follow up evaluation on the Kohler 15 kW low CO emission generator showed higher levels of CO when compared to results obtained from the initial evaluation. Average onboard environmental CO concentrations measured at various locations on the houseboat were generally single digit concentrations. Inspection of the catalytic converter element showed complete degradation of the ceramic element that composes the catalytic converter. The catalytic converter was replaced and CO concentrations were again consistent with the results obtained from the initial evaluation. |
