Device and method for the combustion of waste oil

A vapor eliminating device for eliminating gaseous components from a circulating liquid, comprising:

• a center block having a float housing secured to a top surface thereof defining a float chamber, and a second housing secured to a bottom surface thereof defining a second interior, and the second housing interior having a filter element therein, the filter element separating the second housing into an space interior of the filter element and an annular space between the filter element and the second housing, and the block also having a first liquid flow channel and a second liquid flow channel therein, each liquid flow channel providing for separate fluid communication between the float chamber and the annular space of the second housing, the block also having a liquid flow inlet channel and a liquid flow outlet channel, the inlet channel connected to a liquid inlet line for providing supply of the circulating liquid to the first flow channel, and the inlet channel having venturi means for providing a suction immediately downstream thereof in the first flow channel so that a circulation of the liquid is created from the float chamber to the annular space through the first flow channel and from the annular space back to the float chamber through the second flow channel, the float chamber having a float therein and the float having means for releasably sealing with aperture means in the float housing as a function of the amount of liquid in the float chamber so that any gas trapped in the float chamber can be released through the aperture when a relatively low volume of liquid is held within the float chamber and so that the aperture is closed when a relatively high volume of liquid is held within the float chamber, and
• the liquid outlet channel providing for fluid communication of the liquid from the interior space to a fluid outlet line.
