Title:
ANNULAR SUPERHEATING ELEMENT FOR FIRETUBE BOILERS
Document Type and Number:
WIPO Patent Application WO/2018/111730
Kind Code:
A3
Abstract:
An annular superheater element (10) for superheating steam within firetubes (22) of firetube boilers comprising concentric inner and outer tubes and a specially designed return end cap (16). Saturated steam introduced into the outer tube (14) of said superheater element is superheated while traveling towards the burner end of the tube, is directed into the inner tube (18) by means of the return end cap (16), and travels away from the burner side of the element (10) where it is exhausted for use as superheated steam. While traversing the inner tube, the superheated steam gives off heat energy through the wall of the inner tube to the steam traveling in the outer tube towards the burner end of the tube, conserving energy. The improved superheater element produces superheated steam more efficiently, with less fuel, and steam capable of doing more work, than conventional superheater elements and can be used to retrofit existing firetube type boilers.
