Abstract
A combustion device which includes a forward section in which a baffle has been inserted for stalling the air and fuel mixture as it passes through the torch tip, generating a linear flame. The baffle is designed to include a substantially circular inner portion of wire screen, sintered powdered metal, or ceramic material, surrounded by a solid annular or substantially annular ring. A plurality of ribs extend between the annular ring and the inside of the tube for connecting the annular ring to the tube and for defining a number of outer passages through which air/fuel mixture may pass.
