Abstract

Abstract The disclosed burner guide vane device includes a housing with an inlet pipe and a cylindrical swirl chamber having equidimensional gas inlet ports symmetrically arranged therein in diametral opposition to each other; pivotable vanes or gates are located centrally of these inlet ports on axles to which they are attached by their central portions, the vanes having their radius of curvature 1.2 to 1.6 times greater than that of the swirl chamber.
