Abstract

A method and apparatus for recovering heat from the combustion gas discharged from a submerged horizontal burner. The burner is at atmospheric pressure while an induction fan reduces the pressure inside the heat exchanger and draws the ignited combustion gas through a submerged combustion chamber and through the liquid to a flue. The liquid flows in counterflow arrangement with the combustion gas which further enhances the heat transfer between the combustion gas and the liquid.
