Abstract
A cyclone separator formed by a plurality of parallel tubes and a plurality of fins. Each tube is configured in a multitude of segments. One segment of the tubes forms a cylindrical section, one segment is bent inwardly to form a roof section, and one segment is bent inwardly to form a conically-shaped hopper section. As the circumference and diameter of the hopper section decreases from top to bottom, at least a portion of the tubes are configured, either by being extracted or swaged, to accommodate the decreasing circumference and diameter, which results in an increase in the heat recovery of the water-cooled heat transfer tubes without the need for an intermediate ring header.
Claims23
A vessel comprising a plurality of tubes arranged in a circular pattern to from a wall, corresponding first portions of said tubes forming a cylinder, corresponding second portions of said tubes being bent inwardly from said first portions to form a conically-shaped hopper section extending below said cylinder, a first portion of said second tube portions extending for the entire length of said hopper section, a second portion of said second tube portions being configured to permit the length of said tubes, and therefore the length of said hopper section, to be increased when compared to said length if said second tube portions were not so configured.
The vessel of claim 11 wherein the upper portions of said first tube segments are bent inwardly to form a roof section.
A vessel comprising a plurality of tubes arranged in a circular pattern to form a wall, corresponding first portions of said tubes forming a cylinder, corresponding second portions of said tubes being bent inwardly from said first portions to form a conically-shaped section extending below said cylinder, a first portion of said second tube portions extending for the entire length of said hopper section, a second portion of said second tube portions being extracted from said wall so that the lengths of said tubes, and therefore the length of said hopper section, can be greater when compared to said lengths if said second portions were not extracted.
A vessel comprising a plurality of tubes arranged in a circular pattern to from a wall, corresponding first portions of said tubes forming a cylinder, corresponding second portions of said tubes being bent inwardly from said first portions to form a conically-shaped hopper section extending below said cylinder, at least a portion of said second tube portions having a reduced diameter when compared to said first tube portions so that said lengths of said tubes, and therefore the length of said hopper section, can be greater when compared to said lengths if said second portion of said second tube segments were not so reduced.
