Abstract
An afterburner for clearing soot from a particle-laden gas stream has a housing centered on an upright axis and having a generally cylindrical upper portion having a downwardly open lower end, and a lower portion tapering toward the axis from the lower end of the upper portion and having at the axis a downwardly closed lower end. An exhaust tube opens at the axis into the upper housing portion above the lower end thereof. A feed tube opening tangentially into the upper housing portion above the lower end thereof introduces the particle-laden gas stream tangentially into the upper housing portion. Thus the soot particles of the gas stream move inertially radially outward and descend in the housing to collect at the lower end of the lower housing portion. An electrical heating element at the axis at the lower end of the lower housing portion burns the soot particles collecting therein.
