Abstract: A separation device for the removal of impurities extracted from a flexible conduit from a fuel such as liquefied petroleum gas is described having a housing with an inlet and an outlet, a means for channeling the fuel from the inlet onto an impingement surface in fluid communication with the fuel stream, the surface acting to condense the impurities, a gravity separation means for collecting the impurities removed from the fuel, and a means for channeling the fuel into an outlet.

Abstract: A power burner adaptable for use in conjunction with a wood burning stove employs a blower to produce a forced flow of air and a fuel valve which provides selective fuel communication with a fuel nozzle. Forced air and fuel is mixed in the nozzle and propelled through the nozzle outlet along a generally unidirectional exit path. A target is spaced from the nozzle outlet and interposed in the exit path. A heating assembly which is spaced from the target heats the target to a temperature sufficient to ignite the mixture traversing the exit path. A blast tube surrounds the target and forms an axially extending passageway which functions as a combustion chamber and a passageway for propelling the combusted fuel through an outlet opening of the blast tube. The burner is automatically controlled by an electronic controller.
