Abstract: A system and method for monitoring operation of a pump are disclosed herein. The methods and systems make use of acoustic sensors to collect and analyze data in order to detect cavitation. The disclosed methods and systems may also be used to detect valve damage. The pump may be a positive displacement pump that is employed in a wellbore servicing operation such as pumping a wellbore servicing fluid into a wellbore.

Abstract: A burner apparatus comprising: a liquid fuel discharge means for discharging a liquid fuel; an ignition chamber wherein an ignitable gaseous composition can be ignited to yield an ignited composition; and a gas delivery means for delivering a gaseous, free oxygen source and a combustible gas to the ignition chamber such that the ignitable gaseous composition is provided in the combustion chamber. The ignition chamber is positioned with respect to the liquid fuel discharge means such that, upon leaving the ignition chamber, the ignited gaseous composition will ignite the liquid fuel as the liquid fuel is discharged from the discharge means. Preferably, the gas delivery means includes a conduit through which the free oxygen source is conducted into the ignition chamber. The gas delivery means also preferably includes a passageway, adjacent the exterior of the conduit, through which the combustible gas is conducted into the ignition chamber.
