Experimental research on regeneration of marine engine particulate matter from different sources
In order to study the regeneration performance of particulate matter from different sources,the exhaust particles from different types of marine engines burning different types of fuels were collected.The regeneration test was car-ried out through an external heat source regeneration test bed.The temperature,pressure drop,gas emission,particle emission and regeneration efficiency in the regeneration process were tested.The test results show that:under the same regeneration conditions,compared with the exhaust particles from marine high-speed engines burning diesel and commercial Printex-U,the exhaust particles from marine medium-speed and low-speed engines burning heavy oil have a rapid regeneration period dur-ing the regeneration process,which will form an obvious temperature peak,and the regeneration efficiency can reach more than 80％.However,during the period of temperature peak formation in the regeneration process,the emission concentration of gas and particles generated by the regeneration of heavy oil particles is relatively high,and a high concentration of CO2 emission and nuclear film particles with a particle size of 0～30 nm will be produced.The research results can provide refer-ence for the regeneration conditions and emission control of particulate matter catchers when marine engines burn different types of fuels.
