Abstract
A fire tube with three hollow tube sections, two of which are parallel to each other and one of which is perpendicular to and connects the ends of the first two tube sections. The bottom-most tube section, which contains the burner, has an inner ceramic liner that is made up of one or more separate ceramic tubular sections. An upper set of cooling funs surrounds the top part of the bottom-most tube section, and a lower set of cooling fins surrounds the bottom part of the bottom-most tube section.
Claims14
A fire tube comprising:
- (a) a first tube section comprised of a first length of hollow tube, a second tube section comprised of a second length of hollow tube, and a third tube section comprised of a third length of hollow tube, wherein the third tube section is situated at a rear end of each of the first and second tube sections and is oriented so that a longitudinal axis of the third tube section is perpendicular to a longitudinal axis of each of the first and second tube sections, wherein the first tube section comprises an open front end that terminates in a first flange, wherein the second tube section comprises an open front end that terminates in a second flange, and wherein the first, second and third tube sections are configured to provide a fluid channel through the open end of the first tube section at the first flange, through the first rube section, through the third tube section, through the second tube section, and out the open end of the second tube section at the second flange;
- (b) a plurality of cooling fins that are configured to surround at least a portion of a mid-section of the first tube section, wherein the plurality of cooling fins comprises an upper set of cooling fins that surrounds an upper part of the first tube section and a lower set of cooling fins that surrounds a lower part of the first tube section;
- and
- (c) a tubular and hollow ceramic liner that is situated inside of the first tube section, the ceramic liner comprising one or more separate tubular sections, wherein the ceramic liner comprises two or more separate tubular sections, each of which comprises a front end with a circumferential recess and a rear end with a circumferential protrusion that is configured to fit into the circumferential recess on the front end of an adjacent tubular section.
