Abstract
Abstract A crude oil burner is provided particularly suited for offshore oil well testing,having a plurality of aligned and spaced air cones to the rear end of which crude oil is delivered, and into which air is induced. Air is also available at the space between the cones and at the front of the front cone. Water is sprayed into the flame from a ring at the rear of the front cone and beyond the front of the front cone from a ring at the front of the front cone to provide smokeless combustion.
