Abstract (en)
[origin: US4782793A] The fossil-fuel fired vapor generator has a vertical flue formed of vertical tubes and a funnel at the bottom end which is formed by helically extending tubes. In addition, the helically extending tubes are in communication with the vertically extending flue tubes via bifurcation elements in order to convey the working medium upwardly into the flue tubes. The flue may be of rectangular cross-section with the funnel of similar shape or the flue may be of at least a pentagonal cross-section while the funnel has a rectangular outlet opening.
