Abstract
A steam generating system including an upright furnace section formed by a plurality of tubes, a portion of which have upper and lower tube ends and extend at an acute angle with respect to a horizontal plane, a portion of which extend vertically downwards from the lower tube ends, and a portion of which extend vertically upwards from the upper tube ends. Additional lower and upper vertical tubes are provided which are coplanar with, parallel to, and evenly distributed and interlaced among the tubes extending vertically from the respective lower and upper ends. Means is provided to pass fluid through the length of the furnace section to convert a portion of the fluid to steam or to heat the fluid, the fluid passing upwards first through the additional lower vertical tubes, then through the length of the angularly extending tubes including the vertical extensions thereof, and then through the additional upper vertical tubes.
