  • Patent number: 5394837
    Abstract: A furnace comprising a lower radiant section and an upper convection section, the lower section having associated fuel burners; generally vertically extending first tubular structure suspended in the first section; second tubular structure extending generally horizontally relative to the first section and suspending the first tubular structure; and grid structure extending generally horizontally and supporting the second tubular structure; whereby hot combustion gases produced by the burners flow upwardly in the first section and past the first and second tubular structure and the grid structure to the upper convection section; and the second tubular structures and/or the grid structure are cooled by circulation of fluids therein.

  • Patent number: 4393816
    Abstract: A thermodynamic method is described and claimed for improving the quality of wet steam produced by conventional and once through type boilers. Moisture entrained with such steam is first separated in a steam-water separation vessel. The separated moisture is thereafter vaporized by pressure reduction and flashed to form lower pressure steam and condensate containing dissolved solids. The condensate is utilized to preheat fresh boiler feedwater. The lower pressure steam is condensed and supplements the boiler feedwater to form a hotter combined net feedwater stream containing reduced quantities of dissolved solids. Practice of the method, in association with commercially available boilers producing saturated to moderately superheated steam at temperatures of up to about 970.degree. F. and steam pressures of up to about 2,900 psig, has resulted in increases in the quality of the steam produced from about 70% to about 99% (substantially dry steam).
