Aerosol generating device
First Claim
1. A combustion thermal fogger having a combustion zone and an aerosol (fog) generation zone in which liquid to be fogged is introduced, wherein said combustion zone comprises:
- an outer barrel and an inner barrel substantially concentric with said outer barrel to form an annular space therebetween, said inner barrel sealed to said outer barrel at its distal end and spaced from said outer barrel at its proximate end to provide communication between said annular space and an interior of said inner barrel, said outer barrel having an opening in its proximate end to accept a burner assembly;
a stator assembly having a plurality of radially positioned vanes located at the distal end of said inner barrel to separate said combustion zone from said aerosol generating zone, said vanes angled to intercept a substantially axial flow of gases created in the combustion zone, said vanes meeting at a central point and extending radially to be of substantially the same radius as the radius of the inner barrel opening at its distal end; and
an air inlet means communicating with the annular space between said inner and outer barrels, said air inlet means located proximate the distal end of said inner barrel.

Abstract
An improved combustion-type fogging apparatus and process for applying herbicides, insecticides and the like, as an aerosol is disclosed herein. The apparatus includes an improved combustion chamber with counter-current flow of combustion and supplemental air along with a stator at the downstream portion of the combustion chamber. The combustion chamber also has a hydrocarbon fuel burner to produce hot gases which along with the combustion air and supplemental air forms a hot gas flow into an aerosol chamber wherein a liquid or molten material is introduced for the purpose of being converted into a stable aerosol or fog for introduction into a storage facility or for other purposes of applying an aerosol of an insecticide, herbicide or other liquid or molten material.
