Abstract:
A tubular burner, comprising:a tubular body having a predetermined longitudinal extent that exceeds a transverse cross sectional dimension of said tubular body; a plurality of perforations formed in said tubular body in longitudinally spaced apart relation to one another, said plurality of perforations collectively forming a flame strip; an elongate distributor of substantially the same longitudinal extent as the tubular body and having a smaller cross-sectional dimension than said tubular body; said elongate distributor being slideably disposed within a hollow interior of said tubular body; said elongate distributor having a first open end proximate a first open end of said tubular body, said first open end of said tubular body adapted to receive a combustible fluid; said elongate distributor including an imperforate tubular member and an extension member; said extension member having a length substantially the same as the longitudinal extent of said tubular body; said imperforate tubular member having a length less than the longitudinal extent of said tubular body; a pair of flanges formed integrally with said extension member and extending radially therefrom so that respective outermost ends of said flanges sealingly engage interior side walls of said tubular body along the entire longitudinal extent of said tubular body; said flanges contacting the inner walls of the tubular body to divide the aside of the tubular body into an upper region immediately underneath the flame strip and a lower region into which combustible fluid flows from the imperforate tubular member of said elongate distributor, said combustible fluid passing from the lower region into the upper region through said perforations.
