Splitter-bifurcate arrangement for a vapor generating system utilizing angularly arranged furnace boundary wall fluid flow tubes

摘要

A vapor generating system including an upright furnace section formed by a plurality of tubes, a portion of which extends vertically and a portion of which extends at an angle with respect to a horizontal plane for passing fluid through the length of the furnace section to convert a portion of the fluid to vapor or to heat the fluid. Each angularly extending tube portion bifurcates into two vertical tube portions and a bifurcate fixture is provided at the junction between the respective tube portions. Each of the bifurcates connecting the angularly extending tube portions to their respective vertical tube portions in the upper portion of the furnace section includes a splitter plate to distribute the fluid in the angular tube portion equally to two vertical tube portions.
