What Is a Natural Draft Furnace? | Home Guides | SF Gate

An Uplifting Experience. A natural draft furnace is one that uses natural atmospheric pressure to force the waste gasses of combustion out through the ventilation system. As the fuel in the furnace burns, it creates hot air as well as combustion byproducts, such as carbon monoxide and nitrogen dioxide.


In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.
