Abstract
A vapor generator including an upright furnace section the boundary walls of which are formed by a plurality of tubes, a portion of which extend at an angle with respect to a horizontal plane. Fluid is passed through the length of the furnace section to convert a portion of the fluid to vapor or to heat the fluid. A plurality of vertical bars are provided which define support surfaces for the tubes and which are welded to the tubes for supporting same.
Claims10
A vapor generator comprising an upright furnace section the boundary walls of which are formed by a plurality of tubes, and means for passing fluid through said tubes to apply heat to said fluid;
- one portion of each of said walls being formed by tubes extending at an acute angle with respect to a horizontal plane and another portion of each of said walls being formed by tubes extending substantially vertically, and a plurality of substantially vertically extending support bars disposed at spaced intervals across said boundary walls and connected along their lengths to said tubes along both portions of said walls for supporting said tubes, the portion of each support bar connected to said angularly extending tubes having a series of substantially semi-circular notches formed therein for receiving a plurality of said latter tubes and the portion of each support bar connected to said vertically extending tubes having an elongated notch formed therein for receiving one of said latter tubes.
