ABSTRACT:
A condensing heat exchange economizer wherein upwardly flowing hot flue gas is redirected to flow in a downward direction over a bundle of heat exchange tubes carrying a counter-flowing heat exchange medium to form condensate and cool the flue gas, and the condensate is forced by gravity to flow in the downward direction. The economizer may be in the form of a cylindrical economizer adapted for insertion in an exhaust stack for flue gas. The cooled flue gas may be redirected to flow in an upward direction and merged with a primary flow passage leading to the stack.
