Apparatus for the recuperation of calories from flue gases of gas heaters.

摘要

The flue gases (F) leave a gas boiler after having passed through a horizontal main exchanger (2) with a low pressure drop. Incorporated in this device is a relatively flat and thin auxiliary exchanger (5) directed vertically, offering a low resistance to being passed through horizontally by a gas, and arranged above a trough (18) for collecting condensates. <IMAGE>
