ABSTRACT:
A burner apparatus for burning liquid fuels is equipped with a swirl atomizer nozzle (4), a flame holder (22) that is connected behind the nozzle mouth, and a combustion air delivery duct (8), in which the nozzle (4) is arranged coaxially. A thermally decoupled duct-like heat conductor (10) functions as a fuel vaporizer in the operation of the apparatus. In its main portion, which starts a small distance downstream from the nozzle, the heat conductor has an inside diameter such that droplets in the spray cone from the nozzle tend to impact evenly over the whole area of its inner surface. The heat conductor (10) is of silica nitride. It comprises at least partially a capillary inner layer.
