Abstract
Embodiments described herein methods can be used in particulate filter regeneration, such as particulate filters used for filtering the exhaust of an engine, e.g., a diesel engine. Systems herein can be configured to dispense combustion gas(es) into housing were a particulate filter is contained and to ignite the combustion gases. Methods for conducting a safety verification process of such systems are disclosed, as well as methods for regenerating the filters. Still other embodiments are described.
Claims20
A method for regenerating a particulate filter comprising:
- coupling one or more supply lines, each defining a conduit, to an engine exhaust pipe through at least one of one or more access ports disposed either upstream or downstream of a particulate filter, wherein each supply line is configured to be coupled to a connector, the connector configured to be releasably coupled to the one or more access ports;
- dispensing a fuel through the one or more supply lines and into the exhaust pipe, the fuel dispensed from a first reservoir, the first reservoir different than a fuel source, the fuel source configured to supply a second fuel to an engine;
- and
- igniting the fuel thereby regenerating the particulate filter.
A system for regenerating a particulate filter comprising:
- a first supply line and a second supply line,
- each supply line defining a conduit having a first end and a second end and
- each supply line configured to be coupled to a connector, the connector configured to releasably couple to an exhaust pipe such that the conduit is in fluid communication with the exhaust pipe at the first end;
- the second end of the first supply line configured to couple to a first reservoir comprising fuel such that the first supply line conduit is in fluid communication with the first reservoir, the first reservoir different than a fuel source, the fuel source configured to supply a second fuel to an engine;
- the second end of the second supply line configured to couple to a second reservoir comprising oxygen such that the second supply line conduit is in fluid communication with the second reservoir;
- and
- the connector coupled to the first supply line and the second supply line near their first ends, the connector configured to couple with an access port of the exhaust pipe such that the conduits of the first and second supply lines are in fluid communication with the exhaust pipe.
