Abstract

A compact heat exchanger for a fuel-fired heating furnace. The heat exchanger has a radiative heat transfer section including at least one firetube for containing flue gases as the air to be heated passes over the firetube and a convective section including a shell-and-tube heat transfer apparatus arranged to receive flue gases from the firetube in the shell region and the air to be heated after it passes over the firetube in the tubes.
