EnerYacht: Environmental and Energy Solutions

THE SeaClean DIESEL PARTICULATE FILTER SYSTEM is a custom engineered solution to stop diesel engine soot at its source. The SeaClean Exhaust Treatment system is able to capture over 95 percent of the soot and other materials in a diesel engine's exhaust flow. These materials would otherwise be discharged into the atmosphere, the water, and onto a yacht's clean white hull. DPF filters have been used for many years on generator exhaust outlets, with some success, but increasingly also with many failures. The key to success is in keeping the diesel exhaust temperature high enough to guarantee regeneration in the filter element.


Other particulate filter systems depend on high generator loads to create exhaust temperatures. Wide variations in generator loads can be found when operating a Superyacht with passengers and crew aboard. These variations often mean that the DPF filter clogs and needs frequent cleanings. The SeaClean system is different. It uses a superior quality filter catalyst, and controls the exhaust temperature to the filter electronically to give the optimum temperature for filter regeneration. It does this by first heating the exhaust gas before it enters the filter housing. Soot particles, unburned fuel, and traces of lube oil are trapped in the filter, where the catalyst reduces them to CO2 and water vapor. Much of the odor associated with diesel exhaust is also removed .


In order to give the highest level of soot removal and extend filter life, SeaClean uses the generator's excess capacity to power an electric heating element which is mounted in the exhaust gas stream. Heating power consumption is adjusted in relation to the load on the generator and its exhaust temperature. In operation, when the generator is operating at a low load, the heater uses more generator power, increasing the load and the temperature of the exhaust. At low output operations, the heater functions as an exhaust cooled load bank, providing an increased electrical base load while it heats the exhaust to the correct temperature.


As generator load increases and exhaust temperature rises, power to the heater is smoothly reduced. When the generator load is enough to supply the heat needed for proper regeneration, the heater ceases to consume power, and full generator power is available to carry the higher load.


THE SeaClean DIESEL PARTICULATE FILTER SYSTEM includes a data logger, set point control, and display meters. These enable immediate local monitoring of temperature and backpressure in the exhaust system. Historical temperature and pressure information is recorded to allow oversight of system performance. A High Backpressure alarm is provided and can interface with any alarm and monitoring system.
